An oil seal, also known as crankshaft retainer, is a small device, but essential to ensure the proper engine operation. It plays a key role in all moving parts of an engine, acting as a physical barrier. This mechanical seal fulfils the dual purpose of sealing a rotary shaft to maintain the necessary lubrication (avoiding leaks) and preventing other foreign matter from contaminating shafts and bearings in the rotary shaft equipment.
In conclusion, engine oil seals, power steering oil seals, and motor oil seals are essential components in automotive systems, contributing to the efficiency, performance, and reliability of the vehicle. Understanding the significance of these seals and their proper maintenance is crucial for optimizing the performance and longevity of the vehicle.
In the UK, customers have a range of options for purchasing oil seals. There are several reputable UK gasket manufacturers that offer a wide selection of oil seals to meet various industrial needs.


2. Oil seal structure and functions
When selecting oil seals for wheel hubs and steering mechanisms, it is essential to prioritize quality, durability, and compatibility with specific vehicle models. High-quality oil seals are designed to withstand the demanding conditions of automotive operation, providing reliable sealing solutions that contribute to the overall performance and safety of the vehicle. Choosing reputable suppliers and manufacturers known for producing high-quality oil seals is crucial to ensure the reliability and longevity of these critical components.
Table 2: How to select the seal type
Finding oil spots under a parked vehicle can be both worrying and stressful for any vehicle owner. If the seal’s leak is small, oil may start to accumulate on the underside of the engine. But as the leak gets bigger, the oil leak will become visible in the front side of the engine.
This type of oil seal can withstand only low speed and friction. It is recommended in places where thick fluid or grease is to be sealed. This is not recommended for difficult applications.
