This single row cylindrical roller bearing carries the NUP design, with two ribs on the outer ring, one rib on the inner ring and a loose rib washer, allowing free axial displacement in one direction and giving the bearing a locating function. Bore diameter is 25.0 mm, outside diameter 52.0 mm, width 18.0 mm, net mass 0.156 kg. The reinforced E design provides increased roller load capacity, the cage is a glass fibre reinforced polyamide TVP2 type, limiting speed is 19800 1/min and reference speed 9600 1/min. Radial internal clearance is C3, wider than standard, compensating for interference fits and thermal expansion during operation. The polyamide cage guides the rollers with low friction and supports the reference speed rating, while the NUP configuration permits axial guidance of the shaft in one direction, suiting applications where the bearing must locate the shaft while accommodating thermal growth on the opposite side. No sealing or lubrication is integrated, so grease or oil supply must be provided externally according to the operating conditions.
