YRT basic rotary table Bearings are designed with a radial full roller, two groups of axial needle Roller, cage assembly, an out ring, a L-section Inner ring and the second ring. the out ring and inner ring have fixing holes. Added preload after fitting simplified the unit construction,Shorten the work of fixing, Lowered the high on fixing. so this kind of bearing is particularly suitable for the situatin of High precision, high stiffness and the Union loads with low speed such as index tables and revolving milling heads.See Fig

*this kind of Bearing have axial and radial running precision for your chosen.(HONBbearing05)

YRT120 Rotary Table Bearing

Product Model: YRT120
Structure: rotary table bearing
Inside Diameter:120 mm
Outside Diameter: 210 mm
Thickness: 40mm
Material: 50Mn, 42CrMo

YRT120 bearing can be used to the machine tool and other high precision machinery of the rotary table or sub-set,and also can be used for chuck,measuring instruments and test equipment and rotary table configuration.This bearing requires higher quality or the parts to match it.You must control screw tightening torque when install it.

YRT50 Rotary Table Bearing

Product Model: YRT 50
d: 50mm
D:126mm
H: 30mm
axial dynamic load: 38kn
axial static load: 158kn
radial dynamic load: 28.5kn
radial static load: 49.5kn

YRT50 bearing can be used to the machine tool and other high precision machinery of the rotary table or sub-set, and also can be sued for chuck, measuring instruments and test equipment and rotary table configuration.

YRT precision rotary table bearing is a kind of bearing fixed by a bidirectional thrust bearing and a centripetalguided bearing. They can support radial loads, axial loads from both directions and tilting moments free from clearance and are particularly suitable for bearing arrangements with high requirements for running accuracylike rotary tables, millings heads and reversible clamps.Due to the fixing holes in the bearing rings, the units are very easy to fit. The bearings are radially and axially preloaded after fitting.

Bearing features:
1.High precision: precision at P4, P2.
2.High rigidity: YRT series bearings are with preload.
3.High load capacity: bearings can support axial load, radial load and tilting load.
4.High speed: YRTS series bearings can be applied in the high speed working condition

Sealing/Lubricant:
YRT bearings are supplied with seals. YRT bearings are greased by a lithium complex soap grease and can be lubricated via the outer ring and L-section ring.

Operating temperature:
YRT bearings are suitable for operating temperatures from 30 to 120.
