Item Information

The C9 rotor seal is a compact seal for use as an end seal for low-pressure channels in rotary transmissions. It consists of a wear-resistant basic rubber element and an anti-extrusion ring which increases stability and prevents extrusion into the gap which may be variable due to eccentricity and the rotary motion. The sealing element was designed specifically as an end seal and, due to the layout, is able to withstand higher pressure peaks.
For pressures below 10 bar, we recommend the C5 rotor seal.

• Insensitive to pressure peaks.
• Installation in closed and undercut housings.

Range of application:
Mainly for use as an end-seal in all rotary transmissions of construction machinery, mobile hydraulics and machine tool hydraulics, as well as for low pressure swivel joints.
