Silicone Rubber: Provides exceptional temperature resistance and flexibility. A hardened shaft is often a requirement for oil seals, as softer metals can extrude into the sealing lip, causing a gap that allows fluid to escape.

Spring-loaded designs are also prevalent, ensuring the lip maintains optimal contact force against the shaft, compensating for wear and thermal expansion over time. For environments involving higher temperatures or exposure to aggressive chemicals, seals manufactured from Viton or silicone rubber are often specified to ensure the integrity of the barrier remains uncompromised.
Installation Best Practices and Common Pitfalls Proper installation is paramount to the seal's performance; even the highest quality 07946 oil seal will fail prematurely if installed incorrectly. Nitrile Rubber (NBR): Offers superior resistance to oils and fuels.

The fundamental purpose of any oil seal is to create a physical barrier that retains lubricants within a bearing housing while simultaneously preventing the ingress of external elements such as dust, dirt, and moisture. Technicians must ensure that the shaft and housing are free of burrs, sharp edges, and abrasive particles that could damage the lip during insertion.
