Zero-backlash servo rotary indexing table from Sankyo Automation
The Sankyo Automation RollerDrive Reducer is a precision gear reducer that uses a zero-backlash roller gear mechanism. The unit is constructed from an input shaft and a turret (output shaft) that is assembled with roller followers. The roller followers are preloaded against a screw-like input shaft to eliminate backlash. Sankyo servo indexing tables offer a […]
New Oriental Motor DGII rotary actuators with AZ Series dc input drivers
Oriental Motor now sells an expanded lineup of DGII Series rotary actuators — including two new dc input AZ Series driver options. As the demand for complete high-accuracy and efficient rotary actuators grows, Oriental Motor has answered with the introduction of the AZ Series dc input drivers. This allows for more applications that are using dc […]
What is a rotary indexing table?
Rotary indexing is a process where repeated angular displacement during a machine cycle is followed by motionless dwell. A rotary indexing table is specifically designed to make repetitive moves around a platform. Essentially, they are highly precise work-positioning devices that index parts to be worked or machined in multiple operations. A rotary indexing table is an […]
Direct-drive (DDR) rotary servo tables from IntelLiDrives have tighter resolution
Direct drive torque motor (DDRs) from IntelLiDrives have resolution up to 0.1 arc-sec; Incremental or Absolute encoders; precision cross-roller or ball bearings; and (optional) matching drives. Benefits of direct drive (DDR) from IntelLiDrives IntelLiDrives rotary tables eliminate backlash and provide a stiff mechanical system for highly dynamic applications.
