This single-row cylindrical roller bearing carries two ribs on the outer ring and a smooth inner ring, making it a non-locating (NU-type) design that allows axial displacement between shaft and housing within the bearing itself. Bore diameter is 25.0 mm, outside diameter 62.0 mm, width 24.0 mm, and net mass is 382.0 g. The bearing is fitted with an M1 machined brass cage and reaches a limiting speed of 21500 1/min, with a reference speed of 8200 1/min. Running accuracy is held to P6. The NU design permits free axial movement of one bearing side relative to the shaft, so this bearing is suited to positions where the shaft must be allowed to float axially while radial loads are carried. Radial internal clearance C3 compensates for thermal expansion during operation, and the E design increases roller load capacity within the same envelope dimensions. No sealing is fitted, so lubrication and contamination protection must be provided externally, typically by oil or grease supplied through the housing.
