This cylindrical roller bearing carries radial loads through a two-row, full complement roller set, giving increased load capacity within a compact cross-section. Bore diameter is 55.0 mm, outside diameter 90.0 mm, and width 46.0 mm, with a net mass of 1114.7 g. The outer ring has one rib and the inner ring has three ribs, forming a semi-locating design, type SL18, variant A. Limiting speed is rated at 4550.0 1/min, with a reference speed of 2900.0 1/min. Radial internal clearance is set to CN (Group N), suitable for standard mounting conditions without additional preload adjustment. The full complement roller arrangement increases radial stiffness and load-carrying ability, while the semi-locating configuration allows axial displacement in one direction, accommodating shaft expansion or misalignment during operation. As an open bearing without integrated sealing, it requires external protection and lubrication management, typically with grease or oil, depending on the operating environment and mounting arrangement.
