This cylindrical roller bearing has a bore of 40.0 mm, an outside diameter of 80.0 mm, and a width of 23.0 mm, with a net mass of 0.534 kg. It is a single row NU-type design with two ribs on the outer ring and a smooth inner ring, allowing free axial displacement and making it a non-locating bearing. The brass cage (M1) and reinforced E design support a limiting speed of 16300 1/min and a reference speed of 6300 1/min. The radial internal clearance falls in group C3, giving extra clearance to compensate for thermal expansion during operation. Running accuracy is held to P6 tolerance, suitable for applications requiring precise shaft guidance under radial load. Since the design allows axial movement between inner and outer rings, it functions as a floating bearing, accommodating shaft length changes without inducing axial preload.
