RNA 4900 Standard Needle Roller Bearings without Inner Ring
Metric Needle Roller Bearings
Needle Roller Bearings have a high load carrying capacity and can operate at high speeds. They have slim design and are suited where radial space is limited. They are available with or without an inner ring and seals.
Needle roller bearings without inner ring offer technically the best bearing arrangement solution if the shaft raceway is hardened and ground. This allows for the use of larger shafts and design alternatives.
