Description
This spherical roller bearing accommodates radial loads with self-aligning capability, compensating for shaft deflection and misalignment. It has a tapered bore (taper 1:12), bore diameter 480.0 mm, outside diameter 650.0 mm, and width 128.0 mm. Net mass is 120.0 kg. Limiting speed is 1040.0 1/min, reference speed 570.0 1/min. Main dimensions comply with DIN 635-2, design B. The tapered bore (K) allows mounting on an adapter or withdrawal sleeve, simplifying fitting and enabling adjustment of the radial internal clearance during installation. Radial internal clearance is C3, providing extra clearance to offset thermal expansion during operation. The machined brass cage (MB) guides the rollers and withstands elevated operating temperatures and higher speeds. Relubrication follows the standard feature, permitting grease replenishment during service without dismounting the bearing.
