Needle Roller Bearings NK21/16 have a high load-carrying capacity and can operate at high speeds. They have a slim design and are suited where radial space is limited. They are available with or without an inner ring.

Needle roller bearings without an 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.

Applications and industry: AGRICULTURE, AUTOMOTIVE, CEMENT INDUSTRY, CRUSHER INDUSTRY, HEAVY MACHINERY EQUIPMENTS, HOME APPLIANCES, MINING SECTOR, METAL INDUSTRY, FLUID MACHINERY, TEXTILE INDUSTRY
