There are a wide range of oil seals to select from for any number of uses, so this guide will break down the most common seals to help you choose the right one for whatever piece of machinery you are working on.
The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.

An oil seal is a type of mechanical seal used to prevent the leakage of oil from machinery components. The dimensions of an oil seal are usually specified in terms of its inner diameter, outer diameter, and thickness. For example, a 38x52x7 oil seal has an inner diameter of 38mm, an outer diameter of 52mm, and a thickness of 7mm.
Loosen the securing-clamp bolt at the base of the distributor, then carefully withdraw the distributor.
Another advantage of the CMR5H spark plug is its longevity. Made from high-quality materials, this spark plug is designed to last for a long time, providing reliable performance mile after mile. This not only helps to save you money on frequent spark plug replacements but also ensures that your engine continues to perform at its best.Despite being a great substitute for more expensive high temperature resistant materials, polyacrylate has a problem of poor water compatibility and cold flexibility.
Furthermore, its compatibility with a broad range of vehicles makes the BR7EF a versatile solution. Whether it's a compact car, a truck, or even a high-performance sports car, these spark plugs can deliver optimized performance, tailored to each vehicle's specific needs.Oil seals can also be known as rotary shafts seals, shaft seals, lip seals, elastomeric seals, and more.
Extra precautions are necessary to avoid damaging the seal when navigating over splines, keyways, or threads. Ample lubrication helps protect the seal lip during this delicate process. The spark plug, typically made from materials like nickel-alloy or iridium, is nestled within the engine's combustion chamber. Its primary function is to generate the spark that ignites the air-fuel mixture, initiating the combustion process. This spark, timed precisely by the ignition system, propels the piston, driving the chain around the guide bar, ready to cut through even the toughest wood.
