Description

Fibre-reinforced compound sliding bearing in wound technology | Maintenance-free | Highly resilient COM-KU®/D-438 Wear rings are a self-lubricating and maintenance-free compound guide ring. It has good sliding properties and is suitable for high loads (also impact loads and with edge pressure). Good damping properties, very suitable for low sliding speeds, good chemical resistance, long service life. The use of this guide ring simplifies the design of the cylinder head. Easy mounting possible in closed and undercut installation spaces.
