💡 What is a single-lip shaft seal used for in rotary equipment like pumps and gearboxes? A single-lip shaft seal is a handy component that keeps oil and grease in while keeping contaminants out, protecting bearings and gearbox internals. In short, it prevents leaks and shields moving parts. - Protects sealed ball bearing assemblies and reduces leakage in linear slide unit and rotary shaft setups - Ideal for pumps, compressors, gearboxes and automotive engine components where low friction is needed - Low cross-section rubber-on-steel design fits tight housings and tolerates oil and temperature changes
