CR Standard 55x75x9 Metric Rotary Shaft Lip Seal (NBR) - Industrial Grade High-Pressure Seal
This premium 55x75x9 metric rotary shaft lip seal is engineered to the demanding CR standard, ensuring exceptional performance in industrial machinery. Designed specifically for shaft diameters (d) of 55mm and housing bores (D) of 75mm, with a compact width (B) of 9mm, this seal utilizes robust Nitrile Butadiene Rubber (NBR) material. NBR provides excellent resistance to mineral oils, greases, and standard hydraulic fluids, making it the ideal choice for general industrial applications where effective fluid retention and contamination exclusion are critical to machine longevity. The common SC design (metal case covered with rubber) ensures secure installation and superior stability within the housing bore, even under minor bore imperfections.
Optimized for high-speed rotary motion and differential pressure applications typical in pumps, gearboxes, and heavy-duty electric motors, this seal minimizes friction while maximizing sealing integrity. By preventing costly lubricant leakage and ingress of water, dust, and abrasive particles, our 55x75x9 seal drastically reduces unexpected downtime and maintenance costs. Invest in CR-standard reliability to secure long-term operational efficiency and maximize the lifecycle of your critical rotating equipment. Suitable for temperature ranges from -40°C to +100°C.
