This single row cylindrical roller bearing carries pure radial loads and works as a semi-locating bearing, with two ribs on the outer ring and one rib on the inner ring (type NJ), allowing free axial displacement of the non-ribbed side while providing locating support in the other direction. Bore diameter is 80.0 mm, outside diameter 170.0 mm, width 39.0 mm, and net mass 3.97 kg. The E design provides increased load carrying capacity through an optimized internal geometry. Limiting speed is 5500 1/min, reference speed 4100 1/min. The polyamide TVP2 cage reduces friction and supports stable roller guidance at the stated speed range. Radial internal clearance C3 compensates for interference fits and thermal expansion during operation, keeping the working clearance within the intended range. The separable inner and outer rings simplify mounting and dismounting, and the design suits applications where axial displacement of the shaft relative to the housing must be accommodated while maintaining radial guidance.
