The TROSTEL 1.875x2.441x0.250 M/R NBR Oil Seal is engineered for rotating equipment requiring reliable sealing performance and long service life.

The M/R Profile utilizes a reinforced metal outer case combined with a precision sealing lip designed to maintain effective contact with the rotating shaft. This proven construction helps retain lubricants within the system while preventing dust, dirt, moisture, and contaminants from entering critical machine components.

The reinforced metal case provides excellent dimensional stability and secure housing retention, making the seal suitable for applications exposed to vibration, continuous-duty operation, and industrial environments where equipment reliability is essential.

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 remains one of the most widely used sealing materials due to its excellent oil resistance, abrasion resistance, flexibility, and cost-effective performance.

With dimensions of 1.875 x 2.441 x 0.250 inch, this seal is commonly used in industrial pumps, gearboxes, electric motors, agricultural machinery, conveyor systems, and OEM equipment utilizing inch-size shaft systems.
