A Gear Rack or Rack Gear includes spur gear tooth or helical gear tooth cut on a linear rectangular or round rod. Both round gear racks and linear gear racks serves as a a sector gear with an infinitely large radius of curvature.

The most obvious utilization of a spur gear rack is to convert the rotary motion of a pinion gear into linear motion or vise versa. When assembled, they are referred to as a rack and pinion. Rack gears offer an advantage over ball screws because they have got a sizable load carrying ability and a simple design which allows linking multiple racks to meet your required length.
We carry both rectangular and circular cross-section gear rack styles in a
range of precision pitches. All our in . and metric gear racks have machined ends for applications needing the use of multiple gear racks in a string.
When your machine’s precision movement drive exceeds what can easily and economically be achieved via ball screws, rack and pinion may be the Stainless Steel Gear Rack logical choice. Best of all, our gear rack comes with indexing holes and mounting holes pre-bored. That will save you plenty of time, hassle and expense.

If your travel size is more than can be acquired from a single amount of rack, no problem. Precision machined ends permit you to butt additional pieces and keep on going.
A rack can be called gear rack or simply railing. They are rectangular designed rods that are provided on one part with toothing as being a gear. By utilizing a gear that engages in the toothing of the rack, you’ll be able to move the gear or the rack longitudinally. Tooth racks are used, among other activities, in machines in which a rotational motion must be converted to an easy motion or vice versa.

If power transmission is carried out by gear coupling, module transmission must be used. Usually the module identifies the kind of the gear and it is the ratio between pitch and p. Module adjustments based on the pitch. Here following conversion table.
The current industry standard, these 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears. Compared to plastic gears and racks, they’re better for high-load, high-speed, and durable applications. Also referred to as spur gears.
