Products Details

HOJE offers a wide range of needle roller bearings including needle roller & cage assemblies, drawn cups,s and solid needle roller bearings. They can also be specified as cam followers and track roller bearings by applications. The major application markets include automotive, consumer products, and general industrial goods. Conveyor, Power Tool, Money Counter, and Home Appliance.

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. 
— The stud is either a recessed head type allowing the use of a screwdriver or a hexagon socket head type so as to be mounted and adjusted easily

Are there specific materials commonly used in the construction of track bearings?

Yes, specific materials are commonly used in the construction of track bearings to ensure their durability, load-carrying capacity, and resistance to various operating conditions. Let’s discuss the materials commonly used for different components of track bearings:

  • Outer and Inner Rings: The outer and inner rings of track bearings are typically made from high-quality bearing steels such as chrome steel (e.g., AISI 52100) or stainless steel. These materials offer excellent strength, hardness, and wear resistance. Chrome steel is the most commonly used material due to its favorable combination of mechanical properties and cost-effectiveness. In some cases, specialized alloys or heat-treated steels may be used to enhance specific properties like corrosion resistance or high-temperature performance.
  • Rolling Elements: The rolling elements in track bearings are commonly made from bearing-grade steel or ceramic materials. Bearing-grade steel, similar to the materials used for the outer and inner rings, offers high strength and wear resistance. Ceramic materials, such as silicon nitride (Si3N4) or zirconia (ZrO2), are also used in certain applications where their advantages, such as high hardness, low density, and resistance to corrosion and high temperatures, are desired.
  • Cage: The cage in track bearings is typically made from materials such as steel, brass, or engineered polymers. Steel cages are commonly used due to their strength and durability. Brass cages offer good corrosion resistance and are suitable for certain operating environments. Engineered polymers, such as polyamide (nylon), are used in applications where low friction, noise reduction, or lightweight design is desired.
  • Seals or Shields: The seals or shields used in track bearings are made from various materials depending on the specific requirements. Common materials include rubber or synthetic elastomers for seals, and steel or stainless steel for shields. These materials provide effective protection against contaminants while maintaining proper lubrication within the bearing assembly.
  • Lubrication: Lubricants used in track bearings can vary depending on the application and operating conditions. Common lubrication options include mineral oils, synthetic oils, and greases. The lubricant’s formulation is carefully chosen to provide adequate lubrication, reduce friction and wear, and protect against corrosion and contamination.

Overall, the choice of materials for track bearings is influenced by factors such as load requirements, operating conditions (including temperature and moisture levels), desired lifespan, and cost considerations. By selecting appropriate materials for each component, track bearings can deliver reliable performance and extended service life in a wide range of industrial and mechanical applications.
