This spherical roller bearing has a bore diameter of 65.0 mm, an outside diameter of 140.0 mm and a width of 48.0 mm, with a net mass of 3.667 kg. It is built with a symmetric design featuring two outer ribs (design E1A), a machined brass cage (MA), and a cylindrical bore (bore type Z). The limiting speed is 5000 1/min, with a reference speed of 3800 1/min. Radial internal clearance is C4 (Group 4), wider than standard, which compensates for thermal expansion during operation. The symmetric roller profile and E1A design allow the bearing to accommodate misalignment and carry combined radial and axial loads. The C4 clearance suits applications where shaft and housing fits or temperature rise would otherwise reduce running clearance. The MA cage, machined from brass, supports higher speeds and reduces cage wear under dynamic loading. Relubrication is standard, meaning the bearing is designed for periodic grease replenishment through the housing or bearing itself.
