YRT260 rotary table bearings specifications

Inner ring: 260mm
Outer ring: 385mm
Mounting height: 55mm
Weight: 18.3kg
Structure: combined radial-thrust bearings, 3 row cylindrical rollers
Materials: GCr15
Precision(axial/radial runout): 4μm/2μm
Lubrication type: Grease lubrication
Lubrication hole: Yes
Load direction: axial, radial and tilting moment.

YRT260 rotary table bearings can undertake axial/radial loads and the tilting moment at the same time, in double directions. It's with mounting holes on inner and outer rings, can be fixed directly with bolts.

YRT axial radial bearings are suitable for applications with low rotation speed, and high requirement on the stiffness and running accuracy, such as rotary table, index head(dividing head), etc.

YRTS axial radial bearings have same structure and size as YRT axial radial bearings, but it has different internal structure design, which make YRTS series bearing has higher limit rotation speed, meanwhile provide lower and even friction.
