Product Description

Product Description

These spherical plain bearings have a steel/PTFE sintered bronze contact surface combination and are maintenance-free. The sliding surfaces have to be externally protected from contaminants. These bearings are also available with a wider inner ring and a larger outside diameter (suffix GEH), which enable higher load ratings and larger tilt angles.

• Designed for radial and combined radial and axial loads
• Long service life and maintenance-free
• Suitable for heavy, constant direction loads
• Low coefficient of friction
• High operating temperatures
• High sliding velocities and small operating clearances
