Description of slewing bearing

Slewing ring is a way to withstand the combined loads of large bearings, can withstand greater axial, radial load and overturning moment.

Slewing ring turntable bearings called, some people also call it: the rotary support, maneuver support.

English names were called: slewing bearing, slewing ring bearing, turntable bearing, slewing ring.

Slewing ring in reality very broad industrial applications, known as: "the machine joint" is subject to the relative rotational movement between the two objects, and the need for simultaneous axial and radial forces, tilting moment by machinery required important transmission components. With the rapid development of the machinery industry, the slewing ring in marine equipment, engineering machinery, light machinery, metallurgical machinery, medical equipment, industrial machinery and other industries has been widely used.

Materials of rings and rolling parts
Generally, NTL use carbon-chromium bearing steel GCr15SiMn or GCr15 for rolling parts and surface-haredned steel 50Mn, 42CrMo, 5CrMnMo for the rings.

Material of cages
The cages for NTL slewing bearings include integral cage, segment cage and spacer-type cage. We use 20# steel or ZL102 birmasil for integral and segment cages, PA 1010 resin or ZL102 birmasil or QA110-3-105 albronze for spacer-type cages. In recent years with continuous development of material industry , nylon GRPA55.25 started to be applied for segment cages.

Material of seals
Generally, NTL use NBR or VITON for seals. But there still very few slewing bearings NTL manufactured in early period sealing with felted wool.
