Cylinder Rod

Specified for maintenance teams seeking a dependable alternative spare part, the Cylinder Rod (OEM 550 996 45) is a high-quality aftermarket component for compatible rock drilling and mining equipment within the feed assembly. It transmits piston force through the hydraulic cylinder while providing the running surface used by the rod seals and guides. Typical compatible references in the supplied list include DD311-40, DD320-40 and DD321-40.

The rod is produced with close dimensional control and an application-appropriate surface finish to support smooth seal contact and stable guidance through the cylinder head. This is especially important under repeated reciprocating movement, side loading, hydraulic pressure and exposure to dust or moisture. A correctly finished rod helps reduce seal wear, leakage risk and unwanted play during cylinder operation.
