Rod Seal PRM

The design of the profile PRM is a rod seal/wiper

combination pneumatic sealing element. Set and

sealed two kinds of dust function and a suit also are

considerably smaller and friction values are even lower.

Technical parameter:

Working pressure: ≤ 1.6MPa

Working temperature: -35℃~ +80℃

Surface speed: ≤ 1.0m/s

Working medium: Lubricated as well as dry and

oil-free air(after initial lubrication during assembly)

Standard materials: Polyurethane P2011

Advantages:

Minimum space requirement

Simple housing, cost-efficient in manufacturing

No additional requirements for axial securing

Smooth running due to optimum adjustment of the

functional lips

Zero danger of corrosion since part consists of

polymeric material

Installation:

The self-retaining rod seal/wiper profile PRM is

manually snapped into the installation housing while

the piston rod is disassembled. Care is to be taken to

prevent sharp edges from damaging the wiping and

sealing lips during assembly. Initial lubrication is the

prerequisite for very long operational life.
