Structure of oil seal with back-up ring
Its middle usually has a nylon supporting ring, to meet the lips requirement of bearing pressure, which is usually made of HNBR. We offer the NBR and HNBR material products, customers can choose according to actual demand freedom.Product design
a. It has the characteristics of the engine oil resistance and low friction during operation
b. The design of back-up ring can increase the pressure tolerance and prevent the lip from overturning
Application scenariosFAQ1:Why more and more customers choose S&P rubber seal?
|NBR||-40||125||Good resistance to alcohol,amines, petroleum oils, and gasoline over a wide range of temperature. Also good resistance to caustic salts and fair acid. Poor in strong oxidants, chlorinated hydrocarbons, ketones, and esters. |
|HNBR||-25||140||HNBR is made from NBR by hydrogenation. It has high temperature resistance, abrasion resistance and good physical properties.|
|ACM||-25||150||It is used in diaphragm, hose for automotive application. Good resistance to heat, ozone and oil. Generally attacked by water, alcohol, glycol and aromatic hydrocarbons. The molecular structure contains ethyl acrylate (EA). Butyl acrylate (BA), and methoxy ethyl acrylate (MEA). High BA content get better low temperature resistance, and high MEA content get more oil resistance.|
|EPDM||-40||125||Stable in polar fluids (alcohol, ketone, and glycol), and hydrochloric acid. Due to the low specific gravity, it can compound with large amount filler. |
|VMQ||-60||225||The most widely temperature ranges for application. Good weather and ozone resistance, but poor mechanical property and chemical resistance.|
|FKM||-20||250||Excellent chemical resistance except ester and ketone.|
