CR 42x50x7 NBR Rotary Shaft Lip Seal | Industrial Metric Oil Seal (42mm Shaft)
Rotary Shaft Lip Seals (often referred to as oil seals) are critical components engineered to contain lubricants within rotating equipment and exclude external contaminants such as dust, dirt, and moisture. This 42X50X7 metric seal features a 42mm Inner Diameter (d), 50mm Outer Diameter (D), and 7mm Width (B). Manufactured with a robust metal case and a standard Nitrile Butadiene Rubber (NBR) sealing lip, this configuration ensures compatibility with common industrial oils and greases while providing reliable performance in temperatures ranging from -30°C to 100°C. Designed to meet ISO 6194 standards, this seal provides a precise interference fit to minimize friction while maximizing sealing integrity on high-speed shaft applications.
As a Senior Product Manager, we emphasize that seals bearing the CR lineage (SKF Group) are synonymous with superior durability and reduced total cost of ownership. The precision-molded elastomeric lip minimizes leakage pathways, making this seal ideal for demanding applications including industrial gearboxes, hydraulic pumps, electric motors, and agricultural machinery. Choosing the 42X50X7 CR seal ensures maximized Mean Time Between Failure (MTBF), protecting costly internal components from premature wear and preventing environmental lubricant spillage, thus significantly improving operational reliability and maintaining regulatory compliance.
