Engineered for demanding hydraulic cylinder applications, the Rubber Lip Metal Clad Hydraulic Wiper Ring delivers reliable rod protection by scraping contaminants — dirt, dust, moisture, and debris — from the rod surface on each retraction stroke. The metal cladding provides rigid structural support for press-fit installation, ensuring the seal stays firmly seated in the housing bore under dynamic operating conditions.
Key Features
Metal Clad Outer Case: Provides a secure, interference-fit installation in the cylinder housing — no adhesive or retaining hardware required
Flexible Rubber Wiper Lip: Conforms to rod surface irregularities for consistent wiping action and extended rod life
Dual-Function Design: Excludes external contaminants while retaining a thin lubricating film on the rod for reduced friction and wear
Low Breakout Force: Minimizes stick-slip and ensures smooth cylinder operation across temperature cycles
Wide Material Availability: Available in Buna-N (NBR), Polyurethane (AU/EU), and Fluorocarbon (FKM) lip compounds to match fluid and temperature requirements
Typical Applications
Hydraulic cylinders (mobile, industrial, and agricultural equipment)
Linear actuators and pneumatic cylinders
Machine tool and press ram assemblies
Construction and heavy equipment hydraulics
Installation Notes
Press-fit into the cylinder head bore with the wiper lip facing outward (away from the fluid side). Ensure bore and rod surfaces are clean and within specified tolerances for optimal sealing performance.
