This single-row cylindrical roller bearing carries a bore of 120.0 mm, outside diameter of 215.0 mm, and width of 58.0 mm, with a net mass of 9.19 kg. The outer ring has two ribs and the inner ring has one rib, forming a semi-locating configuration of type NJ that allows axial displacement in one direction while providing guidance in the other. The brass cage (M1) and E design support a limiting speed of 5600.0 1/min and a reference speed of 2500.0 1/min. Radial internal clearance is C4 (Group 4), giving increased internal play to compensate for thermal expansion during operation at elevated speeds or temperatures. The semi-locating arrangement suits applications where one bearing position must absorb axial shaft movement while radial loads are carried reliably. The separable inner and outer rings simplify mounting and dismounting on the shaft and in the housing.
