A Gear Rack or Rack Gear includes spur gear teeth or helical gear teeth cut on a linear rectangular or circular rod. Both round equipment racks and linear gear racks serves as a a sector equipment with an infinitely large radius of curvature.
The most obvious usage of a spur gear rack is to convert the rotary motion of a pinion gear into linear movement or vise versa. When assembled, they are known as a rack and pinion. Rack gears provide an advantage over ball screws because they have a large load carrying ability and a simple design which allows linking multiple racks to meet your required length.
We bring both rectangular and circular cross-section gear rack styles in a
selection of precision pitches. All our inch and Stainless Steel Gear Rack metric gear racks possess machined ends for applications needing the use of multiple gear racks in a series.
Whenever your machine’s precision movement drive exceeds what can easily and economically be performed via ball screws, rack and pinion is the logical choice. On top of that, our gear rack includes indexing holes and mounting holes pre-bored. That saves you plenty of time, hassle and expense.
If your travel length is more than can be acquired from a single length of rack, no issue. Precision machined ends permit you to butt extra pieces and continue going.
A rack is also called equipment rack or just railing. They are rectangular shaped rods that are given on one side with toothing just like a gear. By using a gear that engages in the toothing of the rack, you’ll be able to move the apparatus or the rack longitudinally. Tooth racks are used, among other things, in machines where a rotational motion should be converted to a straightforward motion or vice versa.
If power transmitting is completed by equipment coupling, module transmission can be used. Usually the module identifies the type of the gear in fact it is the ratio between pitch and p. Module changes according to the pitch. Here following conversion table.
The current industry standard, these 20° 
pressure angle gears have thicker, more powerful teeth than 14½° pressure angle gears. Compared to plastic-type gears and racks, they’re better for high-load, high-speed, and heavy duty applications. Also called spur gears.
