YRT120 Slewing Bearing Rotary Table Bearing
The YRT120 bearing is a turntable slewing bearing with an inner diameter of 120 mm , an outer diameter of 210 mm, a width of 40 mm. It typically uses P5 P6 PO grade precision tolerances and GCr15/GCr15SiMn balls, Its dynamic radial rated load is approximately 102, its static radial rated load is approximately 540. It uses 0.1 standard radial clearance, open type, NBR. together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Application: excavator,construction machine

rotary table bearings structure:
rotary table bearings are axial and radial combined cylindrical roller bearings, which are fixed by a bidirectional thrust bearing and a centripetal-guided bearing.
They can support radial loads, axial loads from both directions and tilting moments free from clearance.
For the convenience of transportation and fixing, two or three symmetrical screws are fastened to the two rings in order to prevent rollers and rings generating collisions which influence bearing accuracy.
rotary table bearings application:
1.Precision machine tools
2.precision turntable, NC rotary table
3.Rotation part of machine tools
4.Inspection instrument,medical equipment
5.Indexing plate of other precision machines' etc
