1. Instruction of Needle Roller Bearings:
Needle roller bearings are roller bearings with cylindrical rollers that are small in diameter. Despite their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.
2. Needle roller bearings design include:
- 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).
