Table 2 a): Common types of oil seals (with spring)
In addition to its durability, the 25x47x7 oil seal is also known for its ability to operate effectively in a wide range of temperatures and environments
. Whether in extreme heat or cold, the seal is able to maintain its integrity and provide a consistent barrier against oil leaks. This versatility makes it a popular choice for use in a variety of industries and applications.ISO 6194-1 1)
An oil seal, at its core, serves as a barrier, preventing the leakage of lubricants while also keeping contaminants like dust and debris from entering mechanical systems. The 35x72x10 dimensions denote the size of the seal, with '35' indicating the inner diameter, '72' representing the outer diameter, and '10%' being the lip thickness. The '20' typically refers to the oil seal's material composition or specific properties, which could denote a certain percentage of an additive or material blend. An oil seal's primary function is to create a barrier between lubricants and the external environment. It is designed to withstand the rigors of heat, pressure, and physical motion, all while keeping oil in and water, dust, and other pollutants out. The effectiveness of these seals is paramount; a failure can lead to oil leaks, reduced lubrication, increased wear and tear on moving parts, and ultimately, catastrophic equipment failure.
NNK belongs to NOK-CN factory, we have more than 150 employees and strong delivery capacity. Our technicians are experienced, we have been committed to the sealing industry for decades, and have independent research and development capabilities. Our metal shells are produced by ourselves, and the quality is guaranteed. Our rubbers are all imported materials, and each product is strictly tested.If you need please contact us.
Ultimately, oil seals are devices that help to exclude dust and dirt, etc., while at all times retaining the lubricant in the piece of equipment.
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.
The mating surfaces of the head or block must be perfectly clean, flat and smooth.
