Low-Precision Rack & Pinion Drive Systems
These systems utilize our our Planetary and Servo-Worm Reducers, to rigidly support and drive a hardened & ground pinion. The rack used in these systems is induction-hardened, which has a quality level of DIN 10 (~AGMA 8) and teeth hardened to 50 to 55 Rc.
These drives are perfect for a wide range of applications, including heavy axis drives with no accuracy requirements, traveling gantries & columns, pick & place robots, and material handling systems. Heavy loads and duty cycles can be easily handled with these drives.
Our Automatic Lubrication Systems are highly recommended for use with these drives, providing continuous grease lubrication to the rack & pinion tooth flanks to preserve the quality and lifetime of the gearing.

Specifications
The system precision, including the pitch error and backlash, can be found below:
| System Precision Level: |
Rack Type & Class: | Rack Quality Level: |
Rack Pitch Error: | Rack & Pinion Minimum Backlash:* |
|---|---|---|---|---|
| Low | Induction-Hardened (BR) |
DIN 10 (~AGMA 8) |
< 0.200 mm per meter |
0.08 mm |
*The rack and pinion backlash depends on the alignment of the rack to the linear guides.
Our right-angle systems utilize our High-Torque (HT), High-Performance (HP) and Economy (E) Servo-Worm Reducers, to support and drive a hardened & ground pinion shaft. These reducers are available in six sizes and have ratios from 4.75:1 to 52:1 (higher ratios available with planetary-worm reducers). These reducers have options for keyed, compression or flanged outputs, which rigidly support our pinion.
The maximum drive force that each system can handle (with safety factor 1.0) is listed below; this should be compared to the application peak force, which can be calculated here, or by filling out our Application Sheet.

Our ZTR & ZR Rack & Pinion Drive Systems utilize our Precision Planetary Reducers with an ISO 9409-1 output flange to provide a rigid support for a hardened & ground helical pinion. This provides tight integration of the driven load while allowing replacement of the pinion if needed. These systems are available in seven sizes with backlash levels down to one arc-minute and ratios from 4:1 to 100:1.
The maximum drive force that each system can handle (with safety factor 1.0) is listed below; this should be compared to the application peak force, which can be calculated here, or by filling out our Application Sheet.
