Product description

1.Features

2.Materials

In general, Nitrile Butadiene Rubber (NBR) is selected;
When the operating temperature is higher than 100°C, or extreme resistance to chemical media, fluororubber FKM shall be selected.

3.Performance

Easy to install, can be stretched normally and relies on the elasticity of the rubber itself to keep it tightly wrapped around on the rotating rod;
The contact pressure of the lip is small, and the contact pressure decreases with the increase of the line speed, and the wear resistance is good;
Some degree of rod eccentricity is allowed;
Effectively prevent the intrusion of dust, powder, water, grease, etc.

4.Operating Conditions (The following limit values cannot occur at the same time.)

Speed: ≤15m/s (Depends on the material of the rubber);
Temperature: -30°C to +180°C (Depends on the material of the rubber);
Medium: water, dust, powder, grease, etc.

5.Recommended Friction Surface Quality
