The rotating end face is sealed with pure rubber to prevent external dust, powder, water and their mixtures and grease from entering the bearing or sealing system. Can be used in most bearings and can be used as a secondary seal in harsh environments where the primary seal is prone to failure.
Features：
The rotating end face is sealed with pure rubber to prevent external dust, powder, water and their mixtures and grease from entering the bearing or sealing system. Can be used in most bearings and can be used as a secondary seal in harsh environments where the primary seal is prone to failure.
Material：
Under normal circumstances, nitrile rubber NBR is used;
When the operating temperature is higher than 100 ℃, or in the case of extreme chemical resistance, fluorine rubber FKM is selected.
performance：
Easy to install, it can be stretched normally and tightly wrapped on the rotating shaft by the elasticity of the rubber itself;
The lip contact pressure is small, and the contact pressure decreases with the increase of the linear speed, and the wear resistance is good;
A certain degree of shaft eccentricity is allowed;
Effectively prevent the intrusion of dust, powder, water, grease, etc.
Working conditions：
Speed: ≤15m/s (depending on the rubber material)
Temperature: -35℃~+180℃ (depending on the rubber material)
Medium: water, dust, powder, grease, etc.
