Rotary shaft seals OCS NBR-70 NBR-70 0.5 -20°C+110°C 12

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

Rotary shaft seal type OC in NBR-70 (black) is a single-acting standard rotary shaft seal that consists of a closed metal cased housing with a metal insert and a sealing lip with a spring. The OCS type has an additional protective dust lip which protects the main sealing lip from outside contamination. The reinforced closed metal cased housing gives this seal more rigidity with a tight and accurate fit.

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
• Good resistance to many mineral oils and greases
• Good heat resistance
• Good for low friction and low heat
• Wide range for large dimensions
• 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 applications, agricultural machinery and forestry.

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
The additional sealing lip can cause increased temperature because of friction.
For special applications that require high temperatures or pressure, other materials and models can be used. Please see our other rotary shaft seals.
