Industry information
(1) the roller bearing housing is divided into two kinds, one is pressing bearing housing, a bearing housing (gray cast iron). Stamping bearing housing is mostly used for welding with steel pipe, cast iron bearing housing and steel tube extrusion.
(2) stamping bearing housing is characterized by good sealing, strong bearing capacity, the biggest characteristic of the cast iron bearing housing is high, but the bearing capacity is lower than that of the punch bearing housing.
(3) the structure is reasonable and the seal is reliable. The roller is provided with two sealing, high manufacturing precision, and special grease is applied in the gap, which can effectively prevent dust, gas, liquid and other corrosive medium from entering the inside of the roller.
(4) excellent corrosion protection performance. The roller body and seal are made of polymer materials, corrosion resistance. In corrosive occasions, the service life can reach 5 times of the ordinary roller. Polymer corrosion support and specifications, including Phi 89, Phi 108, Phi 133, Phi 159 4 major series, more than 30 varieties, can also according to user requirements for the manufacture of non-standard support and accessories. Roll body material has MC nylon and polyamide two categories, according to the use of corrosive substances in the environment of the characteristics of choice.
