What is a hydraulic cylinder gland?
A hydraulic cylinder gland is the component located at the rod end of many hydraulic cylinders. It provides the interface around the piston rod and commonly accommodates rod seals, guide elements and other sealing or retention features depending on the cylinder design.
The exact gland geometry varies with cylinder architecture, rod diameter, sealing arrangement, pressure requirements and mounting design.
What does a hydraulic cylinder gland do?
- Provides the rod-end interface of the cylinder.
- Supports the sealing arrangement around the piston rod.
- Helps guide and maintain alignment of the rod within the cylinder assembly.
- Can provide a serviceable interface for seals and wear components.
- Contributes to the overall structural integrity of the cylinder end assembly.
What information is needed to specify a gland?
A useful starting point is the rod diameter and the cylinder dimensions. Depending on the design, the manufacturer may also need bore diameter, overall length, mounting dimensions, seal configuration, thread or retaining details, material requirements and a technical drawing.
