Rotary table or YRT bearing consist of a thrust/radial housing washer, a thrust/radial shaft washer, a thrust washer, two axial needle roller and cage assemblies and a group of radial cylindrical roller. Housing washer and shaft washer have bolt hole for install equally spacer. This kind of bearings has high axial load and radial load, and high tilting rigidity and high precision. This bearing can be sued to the machine tool or other high precision machinery of the rotary table or sub-set, and also can be used for chuck, measuring request higher quality of the parts match it.
Rotary table bearings comprise two series:
RT Series:
Offers a high resolution and repeatability
Medium load capacity
Table size: Ø50 to Ø125mm.
Suitable for lightweight positioning to light duty machine tool applications
Uses a thrust bearing system for the table movement.
The units are offered with different gear ratio options.
RT-2
Compact Design.
Ø50mm table.
RM-3
Compact design.
Ø75mm table. RT-3
Low cost.
Ø75mm table.
RT-5
Low profile.
Ø125mm table.
DRO Versions
Any of the RT series with manual control with digital read out.
RM Series:
Offers high resolution and repeatablity.
Table size: Ø75 to Ø200mm.
Suitable for lightweight positioning to heavy duty machine tool applications.
Uses a single pre-loaded roller bearing for the table movement, which eliminates the use of a dual bearing configuration, thus improving axial run-out and wobble.
The units are offered with different gear ratio options.
RM-5
Low cost.
Ø125mm table.
RM-5
Sealed unit option (L1168)
Ø125mm table.
RM-8
High load capacity belt or
direct drive.
Ø200mm table.
DRO Versions
Any of the RM series with manual control with digital read out.
