Are you looking to keep your machinery free from any unwanted leakages but aren’t sure which rotary shaft seal is right for your needs? This guide will provide you with everything you need to know in order to select the right one for your application.
- Oil Seal 30x52x10 A Comprehensive Guide
- When choosing a high-pressure oil seal, several factors must be taken into consideration. The first is the type of fluid being sealed. Different fluids have different properties, such as viscosity and chemical reactivity, which can affect the performance of the seal. It is essential to select a seal that is compatible with the specific fluid being used.
If necessary, lever it gently with a broad screwdriver blade, but take care not to bend the flange or damage the head.
- Lastly, the 'A' at the end denotes the resistor type, which helps suppress radio frequency interference, improving overall electrical system stability. This feature is particularly beneficial in today's vehicles with advanced electronic systems that can be sensitive to electrical interference.
Installation Techniques
- It is also important to check the spark plug wire connections for a secure fit



Helix Seal
HID (High Intensity Discharge)
Without minor lip
Hydrogenated nitrile rubber (HNBR)
It is quite common for a groove to develop at the sealing lip at some point due to long-term use. As a result, the new oil seal no longer fits and seals properly. It is not strictly necessary to replace or repair the entire shaft. Take a closer look at the dimensions first. It may be possible to fit with a slightly narrower or wider oil seal next to the groove. Alternatively, using the Speedi-Sleeve repair kit, repair the running surface under the seal.
An oil seal consists of:
The material of the sealing lip is chosen according to the liquid to be sealed and the rotational speed. For larger shafts, an NBR sealing lip can cope with surface speeds of up to 10-12 m/s, while an FKM lip is suitable for speeds of up to 35-38 m/s.
