This single row cylindrical roller bearing carries two ribs on the outer ring and one rib on the inner ring, corresponding to design NJ. The E design provides increased load capacity through optimized internal geometry, and the bearing runs on a polyamide cage TVP2. Bore diameter is 55.0 mm, outside diameter 100.0 mm, width 25.0 mm, and net mass is 0.8 kg. Limiting speed is rated at 10000 1/min, with a reference speed of 4700 1/min. The rib arrangement makes this a semi-locating bearing, allowing axial displacement of the non-ribbed ring while still providing axial guidance in one direction — useful where the shaft requires free axial movement on one side under thermal expansion. Radial internal clearance is CN (Group N), the standard clearance class, suitable for typical fit and temperature conditions without additional clearance adjustment. The separable inner and outer rings simplify mounting and dismounting in applications with tight shaft and housing tolerances.
