Hydraulic Cylinder Lock Nut

This Hydraulic Cylinder Lock Nut is a precision-machined component designed for securing and sealing hydraulic cylinders.

It is installed by threading into the cylinder body, providing reliable axial fixation and

maintaining sealing integrity under high-pressure operating conditions.

Manufactured with high accuracy CNC machining, the nut features external threads for

firm engagement with the cylinder housing and internal recesses or pin holes that allow

easy installation and removal using specialized tools. Its robust structure ensures long service

life and stable performance in demanding hydraulic systems.
