The TROSTEL Oil Seal 1.406x2.575x0.719 M/R NBR is engineered for industrial rotating equipment where effective sealing performance and equipment reliability are essential.

The M/R profile combines a rigid metal outer case with a precision-engineered sealing lip, providing excellent dimensional stability and secure housing retention. This design is commonly used in industrial applications where vibration, continuous operation, and varying load conditions require dependable sealing performance.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the sealing element offers excellent resistance to lubricating oils, hydraulic fluids, grease, and petroleum-based lubricants. NBR remains one of the most widely used oil seal materials due to its excellent balance of oil resistance, abrasion resistance, flexibility, and economic value. Typical NBR seals operate effectively in temperatures ranging approximately from -40°C to +100°C.

The metal case construction improves installation stability and housing retention while maintaining long-term sealing integrity. With dimensions of 1.406 x 2.575 x 0.719 inch, this seal is commonly used in industrial gearboxes, pumps, reducers, agricultural equipment, power transmission systems, and imported machinery utilizing inch-size shafts.
