Premium 55x90x13 NBR Rotary Shaft Lip Seal | Industrial Oil Seal (CR Equivalent)
This metric 55 X 90 X 13 industrial rotary shaft lip seal is engineered for robust sealing performance in demanding applications, including gearboxes, motors, and hydraulic pumps. Constructed from high-quality NBR (Nitrile Butadiene Rubber), this seal offers exceptional resistance to common industrial fluids, mineral oils, and greases, maintaining flexibility across a broad temperature range (-30°C to +100°C). The single lip design, combined with an integrated garter spring, ensures a constant, uniform radial load on the shaft surface, effectively preventing leakage of lubrication media while excluding ingress of dirt and contaminants, thereby maximizing equipment uptime and extending bearing life.
Designed to meet or exceed the performance specifications of leading industrial brands like CR (Chicago Rawhide standard), this seal provides a cost-effective, high-reliability solution for maintenance, repair, and overhaul (MRO) operations. Its precise dimensions (55mm ID, 90mm OD, 13mm Width) ensure perfect fitment as a direct replacement for standard applications. We prioritize material durability and lip geometry optimization to handle typical shaft speeds (up to 12 m/s) and minor shaft eccentricities, guaranteeing long-term sealing integrity and reducing premature equipment failure caused by lubrication loss.
