Welcome to the widest range of standard racks & pinions in the World! Consisting of both helical & straight (spur) tooth versions, in an assortment of sizes, materials and quality levels, to meet almost any axis drive requirements.
These drives are perfect for a wide range of applications, including axis drives requiring precise positioning & repeatability, traveling gantries & columns, pick & place robots,and handling systems. Heavy load capacities and duty cycles can also be easily handled with this drives. Industries served include Material Handling, Automation, Automotive, Aerospace, Machine Tool and .
The rack product range consists of metric pitches from module 1.0 to 16.0, with linear force capacities of up to 92,000 lb. Rack styles include helical, straight (spur), integrated and round. Rack lengths up to 3.00 meters are available standard, with unlimited travels lengths possible by mounting segments end-to-end. Quality levels available include soft, induction-hardened, quenched & tempered and hardened & ground (up to AGMA 12+ and DIN 4).
Typical delivery time for these standard components is 2 to 3 weeks, which is ideal for OEM's requiring just-in-time delivery schedules. Special and/or modified components are always possible - please consult the factory. For harsh environments, stainless steel rack & pinions are available, as well as coatings such as black oxide and chromium (Armoloy ®).
Advantages of Using Long Racks: Through continuous improvements in production techniques, ATLANTA has been able to reduce the total pitch error for the 1,000 mm long hardened & ground racks, while achieving significant reductions of the total pitch error of 1,500 mm and 2,000 mm long hardened & ground racks.For a comparison of ATLANTA Zero-Backlash Rack & Pinion Drive Systems to Roller-Pinion Systems (RPS), please follow this link.

There are four basic gear rack styles available (click on style for):
| || || || |
These racks have the teeth at an angle (19º 31' 42") to rack length for increased load capacity and quiet operation.
These racks have the teeth perpendicular to rack length, and are traditionally known as "spur".
These racks were designed for mounting directly to most common linear guides.
These racks have a round cross-section and use bushings for support.
Straight: The helical style provides several key benefits over the straight style, including:
