NEEDLE ROLLER AND CAGE ASSEMBLY
(K, K‥T2, K‥S, K‥ZW, KMJ, KMJ‥S, KJ‥S, KV‥S,PCJ….. Series)

A needle roller and cage assembly include needle rollers and a cage that guides and retains the rollers.
These assemblies use both the shaft and housing as raceway surfaces. Consequently, the cross-sectional thickness of the assembly is small, roughly equivalent to the diameter of the needle rollers. 
Because this bearing type has no inner or outer rings, the installation is much easier.
These assemblies are available in both single-row and double-row configurations.
As long as the tolerance limits of the shaft and housing are satisfied, the bearing radial internal clearance can be adjusted.

This bearing type is used for connecting rods in compact and mid-sized internal combustion engines (e.g. outboard engines and multipurpose engines), as well as reciprocating compressors.
 

DRAWN-CUP NEEDLE ROLLER BEARING
(HK, HK‥ZWD, HMK, HMK‥ZWD, BK, BK‥ZWD…… Series)

This bearing type includes an outer ring and needle rollers, which are both drawn from special thin steel plates by precision deep drawing, and a cage that guides the needle rollers precisely.
— This bearing product comprises an outer ring formed through a precision deep-drawing process from a thin special steel blank; needle rollers; and a cage that guides the rollers.
— A hardened and ground shaft or inner ring (IR Series) is used as the raceway.
— This bearing needs no axial clamping due to easy installation and a press-fit in the housing. 
— Both a closed-end type to close around the end of the shaft and an open-end type are available.
— Furthermore, a type with a seal installed on a single side or on both sides is also available.
— The standard type includes a needle roller and cage assembly. In addition to this type, a special type with full complement rollers is available as an option.

 

MACHINED-RING NEEDLE ROLLER BEARINGS
(RNA48, RNA49, RNA59, RNA69, NK, NKS,NA48, NA49, NA59, NA69, NK+IR, NKS+IR ……Series)

This product mainly includes machined components – an outer ring and inner ring, needle rollers, and a cage that guides the rollers. In this bearing, the cage or needle rollers are guided by the rib or side plate of the outer ring. Consequently, the roller and cage assembly cannot be separated from the outer ring.
— Available in both metric dimensions and inch dimensions.
— This product is best-suited to a space-saving design due to its low section height, and large load capacity. 
— Another advantage is high rigidity and high bearing accuracy due to the machined outer ring 
— This bearing can be used with a housing made of light metal, because of its highly rigid outer ring. (Other than NKS small-size products)
— The outer ring has a lubrication hole and lubrication groove. 
— Both single-row and double-row types are available. 
— A type with a seal installed on a single side or on both sides is also available.

THRUST NEEDLE ROLLER BEARINGS
(AXK11, AS11, WS811, GS811,811, 812, 893, 874, K811, K812, K893…… Series)

The product is comprised of a needle or cylindrical rollers, a cage that guides and retains the rollers, and a disk-shaped bearing ring, and is capable of holding an axial load in 1 direction. The mounting surface can be used as a raceway surface when the mounting surface is beat-treated and finished. As a result, the bearing can be supplied without bearing ring raceways.
— Space Saving Design: Best-suited to save space because of its small section height and large load capacity.
— Bearing Types: Currently available bearing ring types are AS, WS, GS, and ZS. The AS type consists of a thin steel disk having undergone surface hardening, while the WS, GS, and ZS types are machined.
— Bi-Direction Axial Loading: This bearing can support large axial loads from both sides.
— Application: This complex bearing is designed to support a machine tool precision ball screw.

CYLINDRICAL NEEDLE ROLLER ROLLER FOLLOWERS
(NA22, RNAB2, NAB2, NATR, NUTR2, NUTW, NATV, NACV…… Series)

The track roller bearing is a needle roller bearing with a thick outer ring, which is applied to the cam roller, CZPT roller, eccentric roller, or rocker’s arm. The track roller bearings are mainly categorized into a stud-type track roller bearing (cam follower) and a yoke-type track roller bearing (roller follower). Various types of roller followers and cam followers are available.
— The bearing type with a cage is suitable for comparatively high-speed running because its rollers are guided by the cage. 
— Having more rollers relative to a given size, a full complement roller type boasts greater load capacity.
— The outer surface is available in both spherical (crowning) profile and cylindrical profile. 
— This cam follower (bearing) is selectively available in both metric and inch sizes.

How do track bearings contribute to the precision, accuracy, and reliability of motion control systems?

Track bearings play a crucial role in enhancing the precision, accuracy, and reliability of motion control systems. They provide several key contributions that ensure smooth and consistent linear motion. Here’s a detailed explanation:

  • Precision Guidance: Track bearings offer precise guidance for linear motion systems. They are designed with close tolerances and accurate geometries, allowing for accurate positioning and control of the moving components. This precision guidance ensures that the desired motion is achieved with minimal deviation or error.
  • Smooth and Consistent Motion: By minimizing friction and providing smooth rolling or sliding surfaces, track bearings enable smooth and consistent motion in motion control systems. They reduce the effects of irregularities, misalignments, or vibrations, resulting in smoother operation and improved accuracy.
  • Repeatable Performance: Track bearings provide repeatable performance in motion control systems. They offer consistent and predictable motion characteristics, allowing for precise and repeatable positioning of the moving components. This repeatability is essential in applications that require high accuracy and consistency, such as CNC machining, semiconductor manufacturing, and precision measurement systems.
  • Load Distribution: Track bearings distribute the load evenly along their length, helping to minimize stress concentrations on specific components. This even load distribution improves the overall stability and reliability of the motion control system. It reduces the risk of component failure, deformation, or excessive wear, contributing to enhanced system reliability.
  • Minimized Play and Backlash: Track bearings are designed to minimize play and backlash, which are undesirable movements or clearances between components. Play and backlash can introduce inaccuracies and reduce the precision of motion control systems. Track bearings with tight tolerances and optimized designs help minimize these undesirable effects, ensuring precise and accurate motion.
  • Stiffness and Rigidity: Track bearings provide stiffness and rigidity to the motion control system. They resist deflection and maintain their shape under load, minimizing any unwanted flexing or bending. This stiffness enhances the overall stability and precision of the system, allowing for precise control and accurate motion even under varying loads or external forces.
  • Resistance to Contamination: Track bearings are often equipped with seals or shields to protect against contaminants such as dirt, dust, or liquids. This protection helps maintain the precision and reliability of the motion control system by preventing the ingress of particles that could interfere with the smooth operation of the bearings or cause premature wear and failure.

By incorporating track bearings into motion control systems, industries can benefit from improved precision, accuracy, and reliability. Whether it’s achieving precise positioning, ensuring consistent and repeatable motion, minimizing play and backlash, or providing reliable load distribution, track bearings contribute to the overall performance and integrity of motion control systems.

How do track bearings compare to other types of bearings like ball bearings or roller bearings?

Track bearings, ball bearings, and roller bearings are all types of rolling bearings used in various applications. Let’s compare track bearings to ball bearings and roller bearings to understand their similarities and differences:

  • Design and Construction: Track bearings, ball bearings, and roller bearings have different designs and constructions. Track bearings, also known as track rollers or track follower bearings, are designed specifically for guided linear or rotational motion along a track or guide rail. They feature an outer ring with a track surface, an inner ring, rolling elements (such as rollers or needles), and a cage. Ball bearings, on the other hand, have spherical rolling elements (balls) sandwiched between inner and outer rings. Roller bearings, as the name suggests, have cylindrical or tapered rolling elements (rollers) between inner and outer rings.
  • Motion and Load Handling: Track bearings are primarily used for guided motion in track-based systems, while ball bearings and roller bearings are used for general rotational or linear motion. Track bearings are designed to support both radial and axial loads and provide smooth and controlled motion along the track. Ball bearings and roller bearings are also capable of supporting radial and axial loads but are typically used in applications where the motion is not constrained to a specific track or guide rail. Roller bearings, with their larger contact area and higher load-carrying capacity, are often preferred for applications with higher loads.
  • Applications: Track bearings are commonly used in applications such as material handling systems, conveyors, cam mechanisms, automated machinery, construction equipment, and agricultural machinery, where guided motion along a track or rail is required. Ball bearings and roller bearings find applications in a wide range of industries and systems, including electric motors, pumps, automotive applications, industrial machinery, and appliances.
  • Friction and Efficiency: Track bearings, ball bearings, and roller bearings all aim to minimize friction and ensure efficient operation. However, due to their different designs and contact surfaces, they exhibit varying levels of friction. Ball bearings typically have lower friction due to point contact between the balls and the raceways. Roller bearings, especially tapered roller bearings, distribute the load over a larger contact area, resulting in slightly higher friction compared to ball bearings. Track bearings, with their track interface, may have slightly higher friction compared to ball bearings or roller bearings due to the rolling elements’ contact with the track surface.
  • Installation and Maintenance: Track bearings, ball bearings, and roller bearings require proper installation and maintenance for optimal performance and longevity. However, track bearings may require additional attention during installation as they need to be properly aligned with the track or guide rail. Regular lubrication and periodic inspection are essential for all types of bearings to ensure smooth operation and prevent premature failure.

In summary, track bearings, ball bearings, and roller bearings have distinct designs and applications. Track bearings are specialized for guided motion along a track or rail, while ball bearings and roller bearings are more versatile and used in a wide range of rotational or linear motion applications. Each type of bearing has its advantages and considerations in terms of load handling, friction, efficiency, and installation requirements. Selecting the appropriate bearing type depends on the specific application requirements, load conditions, motion characteristics, and environmental factors.
