Oil Seal Brief Introduction
Oil seal is also known as rotary shaft seal. They are often called grease, fluid or dirt seals. Oil seal is an integral part in any rotating and moving part assembly. They close spaces between stationary and moving components in mechanical equipment.  An oil seal normally consists of three basic components: The Sealing Element (the nitrile rubber part), the Metal Case, and the Spring. It is a widely used sealing component.

Testing Equipments


1,Hardness testing: hardness testing of various materials to ensure product hardness to meet customer requirements.
2,Tensile machine: according to the material property requirements test tensile force, according to the standard through the test.
3,Microscopic examination: sampling rate of 20%, oil seal surface is fine cracks, there is scrap, no pass; if the sampling failure rate of 3% and above, the whole batch of full inspection, to ensure quality.
4,Aging box: aging of the material, the temperature of 200 degrees and above, aging phenomenon, then scrapped.
5,Vulcanizing apparatus: test the quality of the glue material, the value is within the standard range, and then pass the test according to the standard.
