Also known as a Rotary Shaft Seal, Shaft Seal, Lip Seal, Elastomeric Lip Seal or any variation of these. It is a simple device for excluding dust, dirt, water or any other contaminant whilst retaining lubricant in rotary shaft equipment. Generally, it has been developed as a means of protecting the bearings of rotating shafts.

tc type oil seal. Additionally, TC type oil seals are easy to install and remove, making maintenance and replacement a simple process.
The sizes of industrial oil seals typically range from 0–33cm. These varieties are designed for temperature fluctuations. If your seal matches the intended equipment, the machine will perform optimally.


It is important to regularly inspect and replace worn-out piston oil seals to ensure the proper functioning of the engine. This can help to prevent costly repairs and extend the life of the engine.
Most oil seals consist of some basic elements that configure their structure, such as the sealing element, the metal case, and the spring:

The skeleton oil seal structure consists of three parts: the oil seal body, the reinforced skeleton and the self-tightening coil spring. The sealing body is divided into bottom, waist frame oil seal structure diagram, cutting edge and sealing lip according to different parts. Generally, the inner diameter of the skeleton oil seal in the free state is smaller than the shaft diameter, that is, it has a certain interference. Therefore, after the oil seal is installed on the oil seal seat and the shaft, the pressure of the oil seal edge and the contraction force of the self-tightening coil spring will produce a certain radial tightening force on the shaft. After a period of operation, the pressure will rapidly decrease or even disappear. , Therefore, adding a spring can compensate for the self-tightening force of the oil seal at any time.
