The UNIVERSAL Oil Seal 6.125x7.125x0.625 M NBR is engineered for industrial applications where robust construction and dependable sealing performance are critical to maintaining equipment reliability.

The M profile design incorporates a full metal outer case that provides exceptional rigidity, dimensional stability, and secure housing retention. This construction is particularly suitable for large-diameter shaft applications where equipment experiences vibration, heavy loads, and continuous operation.

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 outstanding balance of oil resistance, durability, flexibility, and cost-effectiveness.

The 6.125 x 7.125 x 0.625 inch size is commonly used in industrial gearboxes, pumps, crushers, mining equipment, conveyors, steel processing equipment, agricultural machinery, and imported heavy-duty machinery operating under demanding conditions.
