Stefa® Radial Shaft Seal, commonly known as radial oil seals or rotary shaft lip seals, are precision-engineered components designed to seal between rotating shafts and stationary housings. They feature a flexible elastomer lip bonded to a rigid metal case and energized by a garter spring for consistent sealing force. They offer a proven balance of sealing reliability, friction control, and application flexibility, with a selection of variants to match cleanroom, high-speed, high-pressure, or contaminant-rich environments. Global support ensures optimized performance, reduced downtime, and easier maintenance across your systems. This is a Custom Article Number with a Customer Specific Design.
