Company News >> Slewing bearing material composition analysis

 Slewing bearings are widely used in many industries, and are called "machine joints". They are widely used in medium and large mechanical equipment and are an indispensable part of some equipment. The slewing ring is composed of a ferrule, a rolling element, a cage and a sealing 
ring.

The materials used are as follows:
 
Ferrule and rolling material In general, the slewing bearing rolling elements are integrally hardened carbon-chromium bearing steel. The ferrule is made of surface hardened steel. When the user has no special requirements, it is generally made of 50Mn steel. However, in order to meet the needs of some special applications, the surface can be hardened according to the specific conditions of use provided by the user. Steel, such as 42CrMo, 5CrMnMo, etc.
 
Cage material
The slewing bearing cage has a structural form such as an integral type, a segmented type, and an isolated block type. The integral and segmented cages are made of 20 gauge steel or ZL102 cast aluminum alloy. The spacer block is made of polyamide 1010 resin, ZL102 cast aluminum alloy, and the like.
 
Seal material
The material for the slewing ring is made of oil-resistant butadiene rubber.
In general, in order to ensure the powerful use of the slewing bearing, the choice of the material to be produced can not be ignored, and only the selection of suitable materials can make the slewing bearing have strong performance.
