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. Integrated with precision bearings and ring encoders, […]

Direct-drive rotary servo tables from IntelLiDrives feature IP-rated ingress protection
Rotary tables with a high IP rating resist ingress of water and external particles — and the IP65 rating of rotary servo tables from IntelLiDrives assures against ingress of dust and small water jets. IP66 rating assures, in addition to IP65, against ingress of powerful water jets. IP67 rating assures (in addition to IP66-level protection) resistance to water […]
New ways of controlling indexing tables for precision motion
There are key differences between fixed-position indexing tables and closed-loop position indexing tables. Here we review them and how to control for maximum accuracy. By Ken Pfahl, Sales Manager | Motion Index Drives Indexing tables come in an array of versions with different speed and dwell settings to satisfy tasks in machine-tool handling, stamping, medical-device […]
Direct drive rotary servo tables fitted with absolute encoders
IntelLiDrives now offers a new series of low-profile PSR300MHS-ABS tables — large-center-aperture direct-drive rotary servo tables fitted with absolute encoders. Benefits of absolute encoders and direct drives in rotary servo tables The major advantage of an absolute encoder over an incremental encoder is that the absolute encoders keep track of position at all times —and provides position as soon as the system gets power.
