Product Introduction:
Skeleton oil seal is a lip type seal used for rotating shafts. The skeleton is like the steel bars inside the concrete component, playing a strengthening role and allowing the oil seal to maintain its shape and tension.
According to the type of skeleton, it can be divided into inner skeleton oil seal, outer skeleton oil seal, and inner and outer exposed skeleton oil seal. The skeleton oil seal is made of high-quality Nitrile rubber and steel plate+spring, with stable quality and long service life.
Material characteristics:
oil resistance, wear resistance, and temperature resistance
Working medium:
mineral oil, synthetic oil, water
Product Usage:
Widely used in machine tool spindles, automotive, motorcycle crankshafts, camshafts, differentials, shock absorbers, engines, axles, front and rear wheels, and other parts.
Functional purpose
1. Prevent mud, dust, moisture, etc. from entering the bearing from outside;
2. Limit the leakage of lubricating oil in the bearings.
