High-Precision 14x20x3mm NBR Radial Shaft Seal (Oil Seal) - CR Standard Replacement - Metric
This industrial-grade 14x20x3mm Radial Shaft Seal is engineered for critical fluid retention and contaminant exclusion in rotating equipment. Constructed from high-durability Nitrile Butadiene Rubber (NBR), this seal provides excellent resistance to mineral oils, hydraulic fluids, and grease across a standard operating temperature range (-30°C to 100°C). The single-lip design incorporates a precision-tensioned garter spring, ensuring consistent, low-friction contact with the shaft surface even under high rotational speeds. Its precise metric dimensions guarantee seamless interchangeability with existing CR standard applications, providing robust performance and extended service life in demanding environments.
Optimized for use in small motors, light-duty gearboxes, agricultural machinery, and pumps, this 14x20x3mm lip seal significantly minimizes maintenance overhead by preventing costly lubrication leakage and protecting internal components from ingress of dust, dirt, and moisture. The robust NBR compound offers superior abrasion resistance compared to standard materials, ensuring dependable operation and reduced downtime. Choosing this replacement seal ensures dimensional accuracy and material quality essential for maintaining the integrity and efficiency of high-speed mechanical assemblies.
