Heavy load capacities and duty cycles can also be easily handled with these drives. The rack product range consists of metric pitches from module 1.
Gear Rack and Pinion
Rack styles include helical, straight spur , integrated and round. Rack lengths up to 3. Typical delivery time for these standard components is 2 to 3 weeks, which is ideal for OEM's requiring just-in-time delivery schedules.
These racks have the teeth perpendicular to rack length, and are traditionally known as "spur".
Gear Rack and Pinion – creation of linear motion
There are four classes of gear racks available and eight different quality levels, each of which is well suited for certain types of applications. Selecting the right gear rack and pinion depends on many things, including accuracy and load requirements, design constraints, and cost.
Sometimes it is possible that two different racks would work for the same application, but each having it's own advantages and disadvantages.
These cycle forces depend on the weight being moved, the speed vs. The ratings are based on fatigue strength with adequate lubrication; breaking strength ratings are much higher.
Service factors need to be applied to these ratings to make a proper selection. The rack mounting screw holding force may also need to be checked.
What is a Module? Module is a metric pitch, inversely related to diametral pitch, e. Your application data will be reviewed by our engineers, who will recommend the best solution for your application.
A thin film of grease or oil should always be on the contacting tooth flanks to ensure there is no metal-to-metal contact, which can damage the teeth. It is recommended to use our Automatic Lubrication System , which pumps grease through a felt gear applicator and meshes directly to the pinion or the rack.
This provides continuous lubrication at the tooth flanks, extending the lifetime and maintaining the quality of the gearing.

Servo Reducers. These racks were designed for mounting directly to most common linear guides.
These racks have a round cross-section and use bushings for support. In most cases, they cost the same as the straight racks! Pitch Deviation is the difference between the theoretical rack length and its actual length. This varies depending on the rack quality selected and is shown in the catalog as GTf.
Rack & Pinion Drive Systems
Some servo systems can compensate for this error by using a laser interferometer to map out the errors. Zero cumulative pitch deviation for long travels is available - please consult the factory. Tooth Quality is the accuracy that the tooth flanks are manufactured to, which affects the running precision, smoothness, backlash and noise level of the axis drive.
