Is the seal you need not available from one of our standard ranges? No problem. We design and supply seals in any material, size and quantity - from very small to very large volumes.
The 38x52x7 oil seal is a popular size that is used in a variety of applications
. It is commonly used in automotive engines, industrial gearboxes, and hydraulic systems. The seal is designed to withstand the high speeds and temperatures that are common in these types of machinery, and it provides reliable protection against oil leakage.38x52x7 oil seal

-50 °C to + 150 °C
High carbon steel wire
(JIS* SWB)
Aluminum alloys and resin (materials with a large difference between the linear expansion coefficients) demand sufficient consideration (as there is a risk of failure due to the increased clearance with the oil seal at high temperatures).
Selecting the right oil seal involves comprehensively evaluating your application’s needs and conditions. Below are the key factors to consider when choosing an oil seal:
For bisphenol-cured VDF/HFP/TFE polymers, calcium hydroxide level should be low and magnesium oxide level should be high to promote adhesion to metal inserts. Thermal black or mineral fillers generally give good adhesion.3 For most adhesive systems, it is necessary to limit postcure temperatures to about 200°C (392°F).3
If you follow the above instructions, the oil seals should work properly. Also watch the video below for an example of the installation process.
The simplest way is to know either the preferred manufacturers part number, the overall sizes of shaft diameter, housing diameter and bore depth, or use our brochure to establish the M Barnwell Services ordering reference. Many of the old traditional names of seal manufacturers have either changed or disappeared in this age of “acquisitions”. If no longer available, we will advise you and offer a suitable alternative seal, from stock whenever possible. If your concern is getting the right seals for the job, you will need to know something about the application as well as the overall sizes. If you have any doubts – contact us, we will help in your seal selection.
