Rotary shaft seals OBS FKM-75

Rotary shaft seals, also known as oil seals, compression glands, simmer rings etc.

Rotary shaft seal type OBS in FKM-75 (brown) is a single-acting standard rotary shaft seal that consists of a metal-cased housing and a sealing lip with a spring. The OBS type has an additional protective dust lip which protects the main sealing lip from outside contamination.
The FKM material can be used for applications at higher temperatures, higher speed and in more aggressive media compared to the NBR material.

The spring is made of stainless steel (AISI 304).

The Rotary shaft seal is designed to seal against grease, oil and water in rotary applications. A standard oil seal ring is designed to run at a maximum pressure of 0.5 bar.

PROFILE

PRODUCT ADVANTAGES
• Easy installation and removal
• Can be used both for static and rotating applications
• Excellent resistance to many chemicals and mineral oils and greases
• Excellent heat resistance
• Excellent for low friction
• Tight and accurate fitting

APPLICATION
Used in almost every industry as a good reliable sealing in rotating machines, shafts, axles, power tools and gearboxes. Often used in heavy engineering application and agricultural machinery.

INSTALLATION
Installation according to DIN 3760. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation all individual parts of the seal must be oiled with system oil.

NOTES
OB has a limited resistance to low-viscosity fluids and should not be used in very dusty environments.

For special applications that require high temperatures or pressure, other materials and models can be used. Please see our other rotary shaft seals.
