CR 42x72x10 Rotary Shaft Lip Seal (NBR) - Premium 42mm ID Oil Seal for Industrial Applications
The CR 42X72X10 Rotary Shaft Lip Seal is engineered for robust performance in demanding industrial environments, ensuring maximum retention of lubrication and effective exclusion of external contaminants. Featuring precision-molded Nitrile Butadiene Rubber (NBR), this seal is constructed with a spring-loaded primary sealing lip to maintain consistent contact pressure against the shaft, even under minor runout conditions. With exact metric dimensions (42mm inner diameter, 72mm outer diameter, and 10mm width), this seal provides a secure and reliable fit for critical applications such as gearboxes, hydraulic pumps, electric motors, and general power transmission equipment. Its durable design ensures long operational life, minimizing downtime and maintenance costs associated with premature seal failure.
Leveraging CR's established heritage in sealing technology, this 42x72x10 seal offers superior compatibility with common mineral oils, hydraulic fluids, and grease, making it the standard choice for general-purpose sealing duties. The high-quality NBR compound is designed to operate within a wide temperature spectrum, typically ranging from -40°C to +100°C, offering stability and resilience across various operating conditions. By choosing this genuine CR specification seal, users benefit from a proven sealing solution that optimizes equipment efficiency and safeguards against catastrophic leaks, delivering reliability that surpasses standard commercial-grade alternatives.
