The cylinder piston rod seal wiper EF applies to anti-twist cylinders. Compared with the EL circular inner hole, the hole is oval EF. It combines three functions: sealed, dust-proof, fixed.

By integral molding, and the use of the polyurethane material P5010 verified after years, EF has the following advantages:

• Only one ring can play a dual role of seals and dust.

• Low assembly costs, reduce inventory requirements.

• The minimum space requirements to ensure that all the features you need.

• difficult to corrosion, by the positioning ring and the dust seal combination eliminates the need for metal snap ring.

• dust seal parts of special design, to avoid dust accumulation.

• Due to the unique design using dynamic sealing lip and polyurethane material, making it less friction and longer life.

• After the initial assembly lubrication, even with dry and oil-free air is also having a very long service life.

Applications

For preventing the rotation of the elliptical cylinder rod seal.

Working Pressure: 10bar

Working temperature: -30 to + 80 ℃

Surface speed: 1m / s

Medium: lubricated air as well as dried and oil-free air (after initial assembly lubrication).

Material

P5010, polyurethane materials (Shore Hardness 90 A)

Installation

During assembly to avoid seal / dust lip is a sharp edge damage. The inside diameter surface of the guide rod and the seal must be positive.

For special requirements (temperature, speed, used for water, HFA solution, HFB fluid, etc. medium), please contact our service department in order to recommend appropriate materials and structures.

The above data are in standard materials and standard media measured. Require specific temperature range depending on the application conditions.
