1. Ring and rolling element material

In general, hard carbon chromium bearing steel is used as a whole for slewing bearing rollers. Manufactured from grade GCr15 or GCr15SiMn steel; turntable bearing caps are made of case hardened steel, usually 50Mn steel, but other brands of case hardened steel can sometimes be selected to meet the host requirements for some special applications (eg 42CrMo, 5CrMnMo, etc.) .

2. Cage material

The cage of the slewing bearing has the structure of the whole, the segment and the separation block. The integral and segmented cages are made of 20-gauge steel or ZL102 cast aluminum alloy.

The separation type is made of polyamide 1010 resin, ZL102 cast aluminum alloy, etc.

3. Sealing ring material

The slewing bearing seal is made of oil-resistant rubber material or cyan rubber material.
