The TROSTEL 1.156x2.314x0.625 M/R NBR Oil Seal is engineered for rotating equipment requiring reliable lubricant retention, shaft protection, and resistance against external contamination.

The M/R Profile is a heavy-duty industrial oil seal design that incorporates a reinforced metal outer case and a precision sealing lip energized by a garter spring. This construction provides excellent dimensional stability and ensures consistent radial sealing pressure against the shaft surface throughout operation.

The spring-loaded sealing lip effectively prevents lubricant leakage while protecting internal machine components from dust, dirt, moisture, and abrasive particles. This helps extend the service life of bearings, shafts, gears, and other critical rotating components.

The reinforced metal case provides secure housing retention and resistance to vibration, shock loads, and temperature fluctuations, making the seal suitable for demanding industrial environments.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the sealing element offers excellent resistance to lubricating oils, hydraulic fluids, gear oils, grease, and petroleum-based lubricants. NBR is widely used throughout industry due to its durability, flexibility, wear resistance, and cost-effective sealing performance.

With dimensions of 1.156 x 2.314 x 0.625 inch, this seal is commonly used in industrial pumps, gearboxes, compressors, agricultural equipment, hydraulic systems, conveyors, and OEM machinery utilizing inch-size shaft systems.
