The OEM Oil Seal 88x125/141x12/15 SP NBR is engineered for demanding industrial and mobile equipment applications where both lubricant retention and contamination protection are critical.

The SP profile is commonly used in wheel hub, axle, gearbox, and heavy-duty rotating equipment applications. Its special flanged design incorporates a larger protective outer section that helps shield the sealing area from external contamination while improving installation stability. This design is particularly beneficial in environments exposed to dust, mud, water spray, and abrasive particles.

The primary sealing lip is energized by a garter spring that maintains consistent radial contact pressure on the shaft surface, ensuring reliable sealing performance throughout the service life of the equipment. The robust construction helps reduce lubricant leakage while protecting bearings and shafts from premature wear.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the sealing element provides excellent resistance to mineral oils, lubricating grease, hydraulic fluids, and petroleum-based lubricants. NBR remains the preferred material for industrial oil seal applications due to its balance of durability, flexibility, wear resistance, and cost-effectiveness.

With dimensions of 88 x 125/141 x 12/15 mm, this seal is commonly installed in wheel hubs, drive axles, industrial gearboxes, agricultural equipment, heavy-duty pumps, and construction machinery.
