Shield material:
We use cold-reduced electrolytic tinplate for the shiled,which is non-toxic with a good characteristics in stamping processing and anti-corrosion,The shield plays a good performance in dust prevention,grease leak-proof and moisture protection etc.
Rubber seal material
Seal material is nitrile rubber,which is the copolymer of acrylonitrile-butadiene.It is the most widely applied sealing material as its excellent performance in oil resistance,elasticity,abrasion resistance,mechanical strength etc.
