This component is used in the following industrial products
A sealing and structural component at the end of a hydraulic or pneumatic cylinder rod.
A critical assembly consisting of the piston rod and its sealing system that prevents fluid leakage while transmitting linear motion in drive mechanisms.
The interface component that connects the carriage/travelling block to the guide rail system, ensuring precise alignment and smooth linear motion.

A wiper seal primarily excludes external contaminants from entering the cylinder, while a rod seal primarily prevents internal fluid leakage. Wiper seals are installed on the external side of the rod gland.
Replacement intervals depend on operating conditions, typically 1-5 years or 1-10 million cycles. Signs for replacement include visible wear, increased contamination ingress, or lubrication loss.
Yes, specially designed wiper seals with low-friction materials (like PTFE composites) can accommodate rod speeds up to 1.5 m/s, though standard designs typically handle 0.5 m/s.
