Elring supplies liquid sealants, head gaskets and also oil seals. The extensive range almost always offers a solution for an engine block and quality is can’t be missed in Elring's product range.
- Furthermore, the oil seal 12 22 5 also helps to maintain the lubrication system of the machinery, ensuring that the moving parts are properly lubricated. This is essential for reducing friction and wear on the components, ultimately improving the efficiency and performance of the equipment.
- Overall, rubber flange gaskets are a reliable and versatile sealing solution that offers numerous benefits for industrial applications. Their flexibility, durability, ease of installation, and material options make them an ideal choice for ensuring a leak-free and efficient operation.


The most common oil seals are the ERIKS types R, RST, M and MST, which correspond respectively to types A, AS, B and BS according to DIN 3760/ISO 6194.
Dimensions
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.
