The PBR Oil Seal 1.563x2.506x0.375 TC NBR is engineered to provide reliable sealing performance in rotating shaft applications where lubricant retention and contamination prevention are critical.

The TC profile is one of the most widely used oil seal designs worldwide. It features a primary sealing lip energized by a garter spring for effective oil retention and a secondary dust lip that prevents dirt, dust, moisture, and external contaminants from entering the system.

Manufactured from NBR (Nitrile Butadiene Rubber), the seal offers excellent resistance to lubricating oils, hydraulic fluids, grease, and petroleum-based lubricants. NBR provides an ideal balance of durability, flexibility, abrasion resistance, and cost-effectiveness, making it the most common sealing material used in industrial applications.

The metal-reinforced rubber-covered construction ensures secure housing fitment while maintaining excellent sealing performance under continuous operation.

With dimensions of 1.563 x 2.506 x 0.375 inch, this seal is commonly used in industrial gearboxes, electric motors, pumps, agricultural machinery, speed reducers, compressors, and imported inch-size machinery.
