Four kinds of special materials for rotary disc bearing
Four major categories of bearing material
1, under normal circumstances, the turntable bearing ring selection of 50Mn, but sometimes, in order to meet the special application host need to use 42CrMo.
2, the rolling body general selection of GCr15SiMn.
3, maintain the type of the type of the whole, sub - type, block type, and so on the different structure type. Integral or segmented hold for 20# steel or ZL102 cast aluminum alloy. The block type retainer is made of Polyamide 1010 resin, ZL102 cast aluminum alloy or QA110-3-1. 5 aluminum bronze.
4, sealing ring material: oil resistant rubber, fluorine rubber, oil resistant rubber. Slewing bearing clearance of slewing bearing clearance is mainly used for compensation turntable bearing parts and host is related to the assembly parts of the manufacturing error and installation error to ensure the bearing of normal use. According to slewing bearing structure type / grade of tolerance and rolling body group of pitch circle diameter, slewing bearing clearance value or given the amount of interference.
