36990/36920 N1/VA833 Railway Tapered Roller Bearing

36990/36920 N1/VA833 is a tapered roller bearing designation used in demanding bearing applications where controlled radial and axial load carrying capability is required. The supplied technical table lists a 177.8 mm bore, 227.012 mm outside diameter and 30.162 mm total bearing width. For purchasing and replacement work, the complete designation should be confirmed because suffixes and special execution codes can define application, material, lubrication or performance requirements. Boyuan Bearing supplies tapered roller bearings for international distributors, bearing traders and industrial customers.

Railway and Industrial Applications

The 36990/36920 N1/VA833 bearing can be considered for railway and heavy-duty bearing applications where a tapered roller bearing is specified. Typical selection factors include shaft and housing dimensions, radial and axial loading, rotational speed, mounting arrangement, lubrication and operating temperature. For railway spare parts, buyers should compare the complete designation and dimensional drawing rather than selecting by bore and outside diameter alone.
