What is the manufacturing process of slewing bearings?
When the user has no special requirements, slewing bearings are generally made of 50Mn steel. However, sometimes other types of surface-hardened steel are used to meet the needs of the host in special applications, such as 42CrMo, 5CrMnMo, etc. The code for the ferrule material and blank supply status is as follows: table rules.
"T" in the slewing bearing table indicates that the ferrule blanks are supplied in a quenched and tempered state, "Z" indicates that the ferrule blanks are supplied in a normalized state. The sealing ring material slewing bearing cages are available in integral, segmented, and isolation block types. and other structural methods, among which the overall and segmented cages are made of No. 20 steel or ZL102 cast aluminum alloy, the isolation block type is made of polyamide 1010 resin, ZL102 cast aluminum alloy, etc., and the isolation block type cage is made of polyamide 1010 resin. , ZL102 cast aluminum alloy or QA110-3-1.5 aluminum bronze.
Oil-resistant rubber, fluorine-containing rubber, oil-resistant nitrile rubber, the commonly used structural methods of slew bearings include single-row ball slew bearings, double-row ball slew bearings, single-row interspersed roller slew bearings, three-row roller slew bearings, ball Column hybrid slew bearings and other different structural methods, the slewing bearing rolling body is made of overall hardened carbon chromium bearing steel, numbered GCr15 or GCr15SiMn steel. The above types of bearings are divided into toothless types according to whether they have teeth and the distribution location of the gears. There are different structures such as external tooth type and internal tooth type. The slewing bearing ring is made of surface hardened steel.
