The TROSTEL 1.313x2.200x0.500 M/R NBR Oil Seal is engineered to provide dependable sealing performance for rotating shafts operating in industrial and mechanical equipment.

The M/R Profile utilizes a reinforced metal outer case combined with a precision-engineered NBR sealing lip. This design provides excellent dimensional stability while maintaining consistent sealing pressure against the shaft surface, helping to prevent lubricant leakage and contamination ingress.

The sealing lip effectively retains oil and grease within the equipment while protecting bearings, shafts, and internal components from dust, dirt, moisture, and abrasive particles. The reinforced metal case ensures secure installation and reliable operation under vibration and continuous-duty conditions.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the seal offers excellent resistance to mineral oils, hydraulic fluids, lubricating grease, gear oils, and petroleum-based lubricants. NBR remains one of the most widely used sealing materials due to its excellent oil resistance, wear resistance, flexibility, and cost-effective performance.

With dimensions of 1.313 x 2.200 x 0.500 inch, this seal is commonly used in industrial pumps, gearboxes, electric motors, agricultural machinery, compressors, conveyor systems, and OEM equipment utilizing inch-size shaft systems.
