A Gear Rack or Rack Equipment consists of spur gear tooth or helical gear tooth cut on a linear rectangular or round rod. Both round gear racks and linear equipment racks can be described as a sector gear with an infinitely large radius of curvature.
The most obvious use of a spur gear rack is to convert the rotary movement of a pinion gear into linear movement or vise versa. When assembled, they are known as a rack and pinion. Rack gears offer an advantage over ball screws because they possess a huge load carrying capacity and a simple design which allows linking multiple 
racks to meet up your required length.
We bring both rectangular and circular cross-section gear rack styles in a
selection of precision pitches. All our inch and metric equipment racks have machined ends for applications requiring the use of multiple equipment racks in a series.
Whenever your machine’s precision movement drive exceeds what can easily and economically be achieved via ball screws, rack and pinion may be the logical choice. On top of that, our gear rack comes with indexing holes and mounting holes pre-bored. That saves you lots of time, hassle and expense.
If your travel length is more than can be acquired from a single amount of rack, no problem. Precision machined ends permit you to butt additional pieces and continue going.
A rack can be called equipment rack or simply railing. They are rectangular formed rods that are given on one aspect with toothing as being a gear. By using a gear that partcipates in the toothing of the rack, it is possible to move the apparatus or the rack longitudinally. Tooth racks are utilized, among other things, in Stainless Steel Gear Rack china machines in which a rotational motion should be converted to a straightforward motion or vice versa.
If power transmission is completed by equipment coupling, module transmission can be used. Usually the module identifies the type of the gear and it is the ratio between pitch and p. Module changes based on the pitch. Here following conversion table.
The existing 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 heavy duty applications. Also known as spur gears.
