series bearing material

Under normal circumstances, turntable bearing rings chosen 50Mn, but sometimes in order to meet the needs of a particular application host selection 42CrMo. Rolling element generally used GCr15SiMn. The holder of the type with integral type, sub-type, isolation block, such as different structural types. Monolithic or segmented retainer using 20 # steel or ZL102 cast aluminum. Isolated block holder 1010 polyamide resin, NNCF series bearing ZL102 QA110-3-1.5 cast aluminum or aluminum bronze. Seal material: oil and rubber, series bearing fluoro rubber, nitrile rubber oil. Turntable bearing structures commonly used form of a single row, double row four point contact ball slewing bearings, double row angular contact thrust ball slewing bearing, cross roller and cross tapered roller wheel bearings, three-row cylindrical roller wheel bearings, slim bearings ball column hybrid wheel bearings, such as different structural forms. According to the distribution series bearing of the above types of bearing parts and whether toothed gears are divided into different structure without gear, external gear type, and the tooth and so on.
