The TROSTEL Oil Seal 2.6875x3.400x0.250 M/R NBR is engineered for industrial rotating equipment requiring dependable sealing performance and long service life.

The M/R profile combines a rigid metal outer case with a precision-engineered NBR sealing lip. This design provides excellent housing retention, dimensional stability, and resistance to mechanical stress during operation. The metal case construction is particularly suitable for industrial applications where vibration, load fluctuations, and continuous operation are common.

Manufactured from NBR (Nitrile Butadiene Rubber), the sealing lip offers excellent resistance to lubricating oils, grease, hydraulic fluids, and petroleum-based lubricants. NBR remains the industry standard for oil seal applications due to its excellent balance of oil resistance, abrasion resistance, flexibility, and cost-effectiveness.

With dimensions of 2.6875 x 3.400 x 0.250 inch, this seal is commonly installed in industrial gearboxes, pumps, electric motors, agricultural equipment, power transmission systems, and imported machinery utilizing inch-size shafts.
