Needle roller bearings NA4936 have a long record of accomplishment as proven machine elements for the design of radially compact bearing arrangements with very high load-carrying capacity. Needle roller bearings with an inner ring are used for applications where the shaft cannot be hardened and ground. The permissible axial displacement of the shaft relative to the housing is limited for bearings with an inner ring. If the permissible axial displacement provided by a standard inner ring is insufficient, it is possible to use an extended inner ring.

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