1. Ferrule and rolling material
In general, the turntable bearing rolling uses the overall hardened carbon chromium chrome steel, it is made of GCr15 or GCr15SiMn steel. The turntable bearing ferrule is made of hardened steel. When users have no special requirements, the ferrule generally uses 50Mn steel to manufacture. But sometimes in order to meet the needs of some special applications, but also use the surface hardened steel of other brands, such as 42CrMo, 5CrMnMo and so on according to users’ specific conditions.
2. Cage material
The cage of the turntable bearing has monolithic, segmented, isolated block and other structural forms. The monolithic and segmented cages are made of 20 steel or ZL102 cast aluminum alloy. Isolated block cages are made of polyamide 1010 resin, ZL102 cast aluminum alloy and so on.
3. Seal material
The material of turntable bearing uses the oil-resistant rubber material or chemigum material to manufacture.
