Rack and pinion drives eliminate system
backlash
A range of zero-backlash rack and pinion drives eliminate system backlash by means of a split-pinion and dual-pinion arrangement, providing ultraprecise positioning and repeatability.
Atlanta Drive Systems offers a range of zero-backlash rack and pinion drives that eliminate system backlash by means of a split-pinion and dual-pinion arrangement, providing ultraprecise positioning and repeatability Positioning accuracy is maintained during acceleration and deceleration, as well as for direction of travel reversals

Racks mount standard linear guide rails
Atlanta Drive Systems has a new range of integrated racks which mount directly to most standard linear guide rails, eliminating the need for additional machining and alignment, saving time and money.
The backlash is eliminated by using two pinions - one to drive the axis and the other to engage the opposite tooth flank and take up the backlash.
Mechanically preloaded split-pinion drives use an axial spring to load one pinion half against the other.
Electrically preloaded dual-pinion drives use two motors, each driving one pinion, which are loaded against each other by means of a special motor controller.
These drives are perfect for a wide range of applications, including traveling gantries and columns, milling machines, and material feel axis drives.
Industries served include materials handling, automation, aerospace, machine tool and robotics.
Typical delivery time for these standard components is only 3 to 4 weeks - ideal for OEMs requiring just-in-time delivery schedules.
Special and/or modified designs are always possible.
