This particular oil seal is designed to accommodate a shaft diameter of 50mm while sealing against a housing with an outer diameter of 90mm, ensuring tight closure and effective sealing. The 10mm width is optimal for creating a sufficient sealing surface to prevent leakage while maintaining a low profile in installations.

One of the primary benefits of shaft dust seals is their ability to protect the machinery's internal components from abrasive particles that can cause friction and wear. Dust and dirt particles can not only damage the shaft itself but also the bearings, gears, and other moving parts within the system. By keeping these contaminants out, shaft dust seals help to extend the lifespan of the machinery and reduce the frequency of maintenance and repairs.
