- Axial lip seals, on the other hand, are designed to provide a barrier against fluid leakage along the axis of rotation. They have a similar design to radial lip seals but are oriented in the axial direction.

The most common and economical material within the sealing industry, Nitrile, is used in many oil applications, the automotive sector for aircraft fuel applications, military and marine applications, and more.


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 addition to its durability, the 25x47x7 oil seal is also known for its ability to operate effectively in a wide range of temperatures and environments
. Whether in extreme heat or cold, the seal is able to maintain its integrity and provide a consistent barrier against oil leaks. This versatility makes it a popular choice for use in a variety of industries and applications.25x47x7 oil seal

In addition to these standardised types, the following special types are also available:
Silicone Oil Seals - Designed to absorb lubricants in order to lessen wear and friction, silicone rotary shafts also offer high thermal resistance and a large temperature range. But, they do not handle abrasions well or interact with oxidized oils.
Oil Seals, also known as fluid seals, grease seals, dirt seals, shaft seals, or lip seals, help to seal the gap between static and moving components in machinery and equipment. Oil Seals used in rotating applications are known as rotary seals.
