- Incorrect Driving: Using an incorrect driving ring size or material can deform and misalign the seal. Always select the correct driving ring for the installation.
Oil seals come cataloged as metric oil seals or imperial sized oil seals. The seals can also be custom-made to match the bearings in new types of machinery. They are installed in practically every type of machine including vehicles, protecting all kinds of precision, precisely-fitted ball bearings, sleeve bearings, and roller bearings.
For more severe oil-seal service at temperatures of 160°C (320°F) or higher for extended periods, more resistant fluoroelastomer compositions are required for long service life. High-fluorine VDF/PMVE/TFE elastomers, along with TFE/olefin FEPM elastomers, are much less susceptible to attack by oil additives. TFE/P fluoroelastomers have the requisite chemical resistance, but have low fluorine content, leading to relatively high swell and to soft vulcanizates with lower wear resistance than desired.
- When it comes to spark plugs, the a7tc spark plug stands out as a popular choice among motorbike enthusiasts. Designed for use in small engines like those found in motorcycles, ATVs, and scooters, the a7tc spark plug offers reliable performance and long-lasting durability.
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.
