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
- NC machine tools
- Ball screw supports
- Tool frames
- Cross slides
- X-Y table positioners
- Transfer tables
caution
- Suitable for use in normal industrial environments, but should not be located in areas where they could be subjected to direct sunlight, an impact blow or temperatures outside of the rated range
- Some chemicals can cause damage
- Polycarbonate bowls should not be exposed to chlorinated hydro-carbons, ketones, esters and certain alcohols
- Cannot be used in air systems where compressors are lubricated with fire-resistant fluids, such as phosphate ester and di-ester types
