CR 43X65X12 Radial Shaft Seal - Nitrile Rotary Lip Seal (43mm x 65mm x 12mm)
The 43X65X12 radial shaft seal, manufactured under the high-reliability standard associated with the CR (Chicago Rawhide, now SKF Sealing) brand, is engineered for demanding industrial rotary applications. This metric sealing solution features precise dimensions (43mm shaft diameter, 65mm outer diameter, and 12mm width) utilizing a standard single-lip, spring-loaded design (R-Type or equivalent) to ensure optimal sealing efficacy. Constructed primarily from high-grade Nitrile Butadiene Rubber (NBR/Buna N), this seal is highly resistant to standard industrial oils, greases, hydraulic fluids, and water-based emulsions, making it the preferred choice for gearboxes, pumps, and electric motor assemblies operating within typical temperature parameters of -40°F to 225°F (-40°C to 107°C).
Investing in CR quality guarantees exceptional long-term performance and minimal risk of premature failure. This component effectively prevents lubricant leakage from the internal housing while robustly excluding external contaminants such as dust, dirt, and moisture that can compromise bearing life and overall system integrity. Designed for fast and consistent installation, the 43X65X12 seal delivers the superior retention capabilities and low-friction operation essential for maximizing uptime and reducing maintenance frequency in critical machinery across manufacturing, agriculture, and heavy vehicle sectors. Its precision dimensions ensure perfect fitment into standard metric seal bores.
