This single-row cylindrical roller bearing carries two ribs on the outer ring and one rib on the inner ring, giving it a semi-locating design that transmits axial load in one direction while allowing free axial displacement in the other. Bore diameter is 120.0 mm, outside diameter 215.0 mm, width 58.0 mm, net mass 9.19 kg. The E design provides an increased roller complement for higher radial load capacity. Limiting speed is 5600 1/min, reference speed 2500 1/min, and the bearing runs with a solid brass cage (M1). Radial internal clearance is C3, wider than normal, compensating for thermal expansion under load and speed. The semi-locating arrangement suits mounting positions where the shaft needs axial freedom in one direction while still being guided radially and axially in the other. The separable inner and outer rings simplify mounting and dismounting on the shaft and in the housing. No integrated seals are fitted, so lubrication and sealing must be provided externally, consistent with grease or oil lubrication at the stated speed limits.
