Slewing Bearings<\/h1><\/div>\n\n\n\n

Slewing bearings, also known as slewing rings or turntable bearings, are large-diameter bearings that allow for rotational movement between two structures. <\/p><\/div>\n\n\n\n

They are designed to support axial, radial, and moment loads also with impact design, making them essential in applications where space is limited. Slewing bearings are generally equipped with mounting holes, internal or external gears, lubricating oil holes and sealing devices, so that the main machine design structure is compact, the guidance is simple, and the maintenance is easy. <\/p>\n\n\n\n

ZMS is a professional slewing bearing and slewing drive supplier in China for 15 years. Externally geared slewing bearing, Internally geared slewing bearing, Gearless slewing ring are available for us.<\/p>\n\n\n\n

Main series:

– Single- row crossed roller series
– Single- row four point contact ball series
– Double-row eight point contact ball bearings series
– Double- row ball series
– Roller and ball combination series
– Three-row roller series<\/p><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n
