Precision Rotary Turntable Bearings

High precision rotary turntables

QCB offers a full range of Rotary Table Bearings equivalent to INA YRT, YRTS and ZKLDF Series.


YRT & YRTS Series


YRT Series is suitable for slow and limited duration operations

YRTS Series has higher limiting speeds and low, uniform torque across the speed range and is thus suitable for use with torque motors.

  • Double direction axial bearing with a radial guide roller Predrilled and ready to fit
  • Rigid and accurate bearing system supports axial, radial and moment loads
  • Axially and radially preloaded after installation
  • Unsealed
  • Available in P5, P4 and P2 precision grades in diameters from 70 - 1800mm diameter
  • Imported to order only

ZKLDF Series

  • Axial angular contact ball bearing
  • Suitable for high speeds
  • High axial and radial load capacity with high rigidity
  • Sealed
  • Suitable for use in rotary tables, milling & grinding heads and test equipment
  • Imported to order only
