Bearing i.e. radial-axial roller bearing, for bearing rotary table on machine frame of machine tool, has U-shaped cross-sectional inner ring including rough outer wall cooperating with clamping element

摘要

The bearing (1) has a U-shaped cross-sectional inner ring (4) including a rough outer wall (27) i.e. particle-radiated surface, cooperating with a clamping element (3) e.g. clamping body freewheel. An outer ring (5) engages in the inner ring. A row of radial roller bodies (6) and two rows of axial roller bodies (7) are arranged between the rings. The clamping element is rotational fixedly connected with the outer ring and engages at a shaft disk that is rotational fixedly connected with the inner ring. The wall includes a roughness ranging from 0.5 micrometer to 1.2 micrometers and is greased. An independent claim is also included for a method for manufacturing a bearing with a braking and/or clamping device.
