Introduction
What Is Skeleton Oil Seal?
The skeleton oil seal is a typical representative of oil seals, generally speaking, the oil seal refers to the skeleton oil seal. The role of oil seals is generally to drive parts that need lubrication and external environment isolation, so as not to let the lubricant leakage. The skeleton is just like the steel reinforcement inside the concrete member, which plays the role of strengthening, and makes the oil seal can keep the shape and tension. According to the structure form can be divided into single lip skeleton oil seal and double lip skeleton oil seal. The secondary lip of double-lip skeleton oil seal plays the role of dust-proof to prevent dust and impurities from outside from entering into the machine. According to the skeleton type, it can be divided into internal skeleton oil seal, exposed skeleton oil seal and assembled oil seal. According to the working conditions, it can be divided into rotary skeleton oil seal and round-trip skeleton oil seal. Used in petrol engine crankshaft, diesel engine crankshaft, gearbox, differential, shock absorber, engine, axle and other parts.
Common Structural Style of Skeleton Oil Seal (Simmerring) Oil Seal
The Materials of The Crankshaft Rear Oil Seal For Benz Size 120*140*13/12 OE 0139971447
Nitrile rubber (NBR): wear-resistant, oil-resistant (can not be used in polar media) temperature resistance: -40 ~ 120 ℃.
Hydrogenated nitrile butadiene rubber (HNBR): wear-resistant, oil-resistant, aging-resistant, temperature-resistant: -40~200℃ (stronger than NBR temperature-resistant ability).
Fluorine rubber (FKM):acid and alkali resistance, oil resistance (resistant to all oils), temperature resistance: -20 ~ 200 ℃ (oil resistance is better than the last two kinds).
Polyurethane rubber (TPU): abrasion resistance, aging resistance, temperature resistance: -20 ~ 250 ℃ (aging resistance is good and excellent).
Silicone rubber (PMQ):heat resistance, cold resistance, compression permanent deformation of small mechanical strength, temperature resistance: -60 ~ 250 ℃ (excellent temperature resistance).
Polytetrafluoroethylene (PTFE): good chemical stability, acid and alkali, oil and other media, wear-resistant, high temperature, high mechanical strength, good self-lubrication.
Generally speaking, the skeleton oil seal often used materials nitrile rubber, fluorine rubber, silicone rubber, PTFE, because of good self-lubricating good, especially after adding bronze effect is better, are used in the production of retaining ring, Gryllis ring, Stereo seals and so on.

The Features of The Oil Seal
a. Prevent mud, dust, moisture, etc. from intruding into the bearing from outside;
b. Limit the lubricant leakage in the bearing. Requirements for the oil seal is the size (inner diameter, outer diameter and thickness) should be in accordance with the provisions; requirements for proper elasticity, the shaft can be properly stuck, play a sealing role; to be heat-resistant, wear-resistant, good strength, resistance to media (oil or water, etc.), long service life.
