Detailed description

Needle roller bearings are roller bearings with slender cylindrical rollers.

These bearings are designed for applications where radial space is limited

but high radial load carrying capacity is required.

*Needle roller bearings designs include:
- Drawn Cup Needle Roller Bearings
- Solid Cup Needle Roller Bearings
- Cage and Needle Roller Assemblies
- Inner rings for Needle Roller Bearings
- Cam and Roller Followers
- Needle Rollers
- Needle Roller Thrust Bearings
- Combined Needle Roller Bearings
Model HK, TA, TLA, open-end drawn cup needle roller bearings with retainer,
Model BK close-end drawn cup needle roller bearing with retainer,
Model SCE, BA, J, JH, drawn cup needle roller bearings (Inch series).

*Features: Thick outer ring provides maximum load capacity and shock resistance with a relatively small radial cross section.
*Benefits: Optimum speed and lubrication-retention capability.

*Application:

automotive transmissions, air-conditioner compressors, bulldozer blades,

overhead traveling cranes, gearboxes, machine tool spindles, copying machines and many more.
