98x120x13 NBR Radial Shaft Seal | Industrial Oil Seal | CR Equivalent Quality
This 98 x 120 x 13 mm high-performance Radial Shaft Seal is engineered to meet demanding industrial sealing requirements. Featuring a precision-machined inner diameter (d) of 98mm and an outer diameter (D) of 120mm, this seal utilizes a robust Nitrile Butadiene Rubber (NBR) lip material reinforced by an internal metal case. It is specifically designed for high-speed rotary applications in gearboxes, heavy-duty transmissions, and industrial pumps where maintaining lubricant integrity and excluding dirt, dust, and moisture is critical for equipment longevity.
Built to stringent quality standards (CR-grade performance equivalent), this seal ensures exceptional durability and minimal friction under continuous operation. The standard NBR compound provides excellent resistance to most industrial oils, greases, and temperatures typically ranging from -30°C to 100°C. Optimized spring loading guarantees consistent radial load distribution against the shaft, maximizing the service life of both the seal and adjacent bearing components, thereby reducing costly maintenance downtime and ensuring reliable operational efficiency.
