The PBR Oil Seal 1.750x2.375x0.375 TC NBR is engineered to provide reliable sealing performance in rotating shaft applications where lubricant retention and contamination prevention are essential for equipment reliability.

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

Manufactured from NBR (Nitrile Butadiene Rubber), the seal provides excellent resistance to lubricating oils, hydraulic fluids, grease, and petroleum-based lubricants. NBR remains the preferred sealing material due to its outstanding durability, flexibility, wear resistance, and cost-effectiveness.

The rubber-covered metal case construction ensures excellent housing retention while improving sealing performance between the seal outer diameter and housing bore.

With dimensions of 1.750 x 2.375 x 0.375 inch, this seal is commonly used in industrial gearboxes, pumps, electric motors, agricultural equipment, speed reducers, compressors, and imported inch-size machinery.
