CR 105x140x13 Industrial Shaft Seal (Oil Seal) | Nitrile Lip Seal for Extreme Duty
This CR-branded high-performance rotary shaft seal, measuring 105mm ID, 140mm OD, and 13mm width, is engineered to provide superior fluid retention and contaminant exclusion in demanding industrial environments. Utilizing premium Nitrile Butadiene Rubber (NBR), this seal offers excellent resistance to mineral oils, hydraulic fluids, and grease across a wide temperature spectrum. The precision-engineered primary sealing lip is spring-loaded to maintain consistent radial load against the shaft, ensuring maximum sealing integrity even under moderate pressure fluctuations and high peripheral speeds typical in gearboxes, pumps, and heavy machinery bearing housings. Its robust construction ensures minimal leakage and maximizes operational uptime.
As a Senior Product Manager, we recommend this CR seal for maintenance professionals prioritizing longevity and reliability over initial cost savings. The quality standard synonymous with CR (a brand leader now part of SKF) translates directly into reduced friction, lower power consumption, and significantly extended service intervals compared to generic alternatives. Implementing this specific 105-140-13 seal minimizes the risk of catastrophic bearing failure caused by lubricant loss or ingress of abrasive particles, ultimately lowering the Total Cost of Ownership (TCO) for critical rotating equipment. This product is ideal for MRO applications requiring proven performance under continuous operation.
