详情

Turntable bearings (sometimes referred to as slewing ring bearings) are 4 point contact thin section type ball bearings that have holes in both the inner and outer rings for easy mounting.   These products were designed from standard thin section bearing geometry.  We just reduced the ID and increase the OD to accommondate bolt holes.  Our intention was to make the bearing easy to mount in an industrial application.  One that would require no additional machining (i.e., turning or grinding) of mating components for proper installation.

 

2.Industrial slewing rings are characterized by high-quality forged pieces of material which are accurately machined, hardened and have ground ball tracks. depending on the execution they are equiped with high-quality internal or external toothing. A turntable / slewing ring bearing can withstand large axial and radial loads and/or large tilting moments.
