This cylindrical roller bearing carries radial loads through a single row of rollers guided by a polyamide cage (TVP2), with two ribs on the outer ring and one rib on the inner ring, giving it semi-locating capability that allows axial displacement in one direction while the inner and outer rings can be separated for mounting. Bore diameter is 45.0 mm, outside diameter 85.0 mm, width 19.0 mm, mass 0.432 kg. Limiting speed reaches 10200 1/min, reference speed 7000 1/min. The E design provides increased roller load capacity within the standard envelope. Radial internal clearance C3 compensates for tighter fits and thermal expansion during operation, keeping running clearance within the intended range. The open design requires external sealing and separate lubrication, and the semi-locating function suits shaft arrangements where one bearing position must accommodate axial thermal growth while the roller-rib guidance still limits radial play under load.
