Some disadvantages of NBR are poor ozone, sunlight and weather resistance as well as limited high temperature and flame resistance. For higher temperature resistance, a much better material to use is Silicone.
Shaft Speed:
There are quite a number of factors to put into consideration when you’re choosing the right oil seal for your application. Some of them are discussed below.
Oil seal performance is affected by not only the type and material of the selected oil seal, but also a variety of other factors, such as operating conditions, total eccentricity, rotational speed, the substance to be sealed, and lubrication conditions.
Figure 9 shows items relating to oil seal characteristics.
First disconnect the battery earth terminal , to avoid the risk of a short circuit while the fuel pipes are disconnected.
Sealing edge This refers to the component of the oil seal that makes contact with the shaft.
It is wedge-shaped to be pressed against the shaft surface and makes contact with the shaft to ensure sufficient sealing performance and suitability for operation at high peripheral speed.
Pick the proper seal for your bearing with the NBC bearing.
What are Oil Seals and how do they work?
Oil seals come with various lip designs, each serving a unique purpose and suitable for different applications. Let’s discuss the most common industry-standard lip designs:
Well-balanced in terms of resistance to abrasion and high and low temperatures
The metal used in the outer case of oil seals is usually made of carbon steel. Upon request, and depending on quantities, a different type of steel (such as stainless steel) can be used.
