description
- Series L nonseparable angular contact bearings have cutaway shoulders on both the inner and outer rings. They can support very high thrust loads in one direction or combinations of radial and thrust loads, but not radial loading alone. They are designed to provide machine tool drive systems with extreme axial rigidity, low drag torque and minimal lateral runout.
applications

- Ball screw supports
- Tool frames
- Cross slides
- X-Y table positioners
