- Poor performance of accessories Dimming lights, difficulty in steering, or an overheated engine can indicate that the belt is not functioning correctly.
One of the key benefits of the 25x47x7 oil seal is its high level of resistance to wear and tear. This makes it an ideal choice for use in heavy-duty machinery and equipment that is subject to constant movement and pressure. The seal is able to withstand the rigors of daily use without degrading or failing, ensuring long-lasting performance and reliability.
Common lip materials available for use in our oil seals include:
Failure to install oil seals correctly can lead to failure. Factors such as knocking the seal into place may cause its spring to tilt in the bore or be out of alignment. Consider switching to a solid adhesive and applying it around the surface of the spring to prevent it from loosening.
One way to identify a seal that has not been fitted correctly is to check the rough shear of the rubber. To resolve this issue, align the mounting tool before positioning the seal in place.
By preventing lubricants from escaping, they protect key components of machinery from being damaged by leaks of various fluids. Everything from car engines to assembly machines use these oil seals to remain free from any harmful interactions that can cause serious and expensive damage to any of their critical parts.
One way to recognize an improperly installed seal is by checking whether or not there is uneven shearing of the rubber after use. If this is evident, adjust by aligning the installation tools properly before pressing the seal into place.
An overview of the different standard types of oil seals and their main characteristics is shown below.


Oil seals are one of the major contact type sealing devices.
• They prevent leakage of the lubricant or other sealed substance, and
• prevent entry of dust and foreign matter (dirt, water, metal powder, etc.) from outside.
(hydrodynamic ribs)
• Rotational speed
• Oil viscosity, etc.
Shaft oil seals are an essential component in machinery and equipment used in various industries. They play a crucial role in preventing the leakage of fluids and keeping contaminants out of the system, ensuring smooth operation and prolonging the lifespan of the machinery.
Smear a little gasket sealant round the cover flange and fit the new gasket to it. Make sure it is flat and straight.
JTEKT provides special seals for use in a wide variety of machines and applications.
Table 5 lists the major special seals, their shapes, and their features.

Entry of dust and debris is one of the most common reasons oil seals fail. For instance, in high-pressure applications, even the smallest sediments can create a gap in the seal, causing the oil to leak and dirt to get in.
