A1

A1 – wiper seal

Descriptions

The purpose of the profile A1 wiper ring is to prevent dust, dirt, grains of sand and metal swarf from penetrating. This is achieved by a special design which largely prevents the development of scratches, protects the guiding parts and extends the working life of the seals.
Oversized diameters ensure a tight fit in the groove thus preventing the penetration of foreign particles and dampness.
The profile A1 wiper ring provides a technically accurate closure at the cylinder; no screwrings and brackets are required. No close tolerances are necessary and no metal inserts. The corrosion which may occur with metal-cased wipers will be prevented.
For the groove close tolerances are not required.
If minor quantities or other diameters are required, these may be cut from the next largest size having the same cross-section.

Features

• Good wear resistance.
• High temperature resistance in case of suitable compound selection.
• Excellent media resistance in case of suitable compound selection.
• Suitable compounds available for special requirements of the chemical process industry.
• Suitable compounds available for special requirements of the food processing industry.
• Product geometry prevents dirt deposits at the front face of the cylinder.
• Installation in closed and undercut housings.

Range of application

The profile A1 wiper ring is designed for axially operated rods in hydraulic and pneumatic cylinders, plungers and rod-guidances.

Operating temperature -35 °C to +100 °C
Sliding speed ≤ 2 m/s

Installation

The profile A1 wiper ring is supplied as a continuous ring. Any pressure on the back of the ring should be avoided. Intermediate sizes may easily be cut from the next largest ring with the same cross-section. The ring is to be cut at an angle of 90° to the new circumference length (+ 2 to 3 % in excess). Due to the excess length the two ends will fit closely together so that no gap will occur. Gluing is not necessary. The wiper can easily be pressed into the groove and will fit perfectly tight.
