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

(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.
