As for the kind of gear racks, besides the usual bar shape, there are circular racks in which the cross sections are circular and flexible racks which may be bent into totally free curve shapes.
When manufacturing equipment racks, due to their bar shape, bending often results. In such cases, corrective procedures using presses are often employed.
Among the apparatus racks’ primary applications are machine equipment and transport devices and when the applications involve transmitting 
linear motions, they are often weighed against ball screws. In those instances, the main benefits of gear racks can be named such as having the ability to satisfy a heavier load by using bigger modules and having no duration limitation by connecting gear racks with completed ends. On the other hand, a good example of the disadvantages of equipment racks contains the occurrence of backlash.
Besides equipment racks with straight collection teeth, there are helical racks which have slanted the teeth. Helical gear racks are paired with helical gears, but because of the slant of the tooth direction, as in helical gears, the mesh generates axial thrust forces.
The straight tooth cylindrical gear for which the radius of the pitch cylinder is infinite and in a bar form is called a gear rack. If it’s sorted by the positions of the apparatus shafts, it belongs to the parallel shaft category. The spur equipment that meshes with a equipment rack is normally called a pinion.
Stainless gears and racks resist rust in damp and wet environments, so they’re commonly found in food-processing plants and the areas with frequent cleaning.
A rack and pinion is a type of linear actuator that comprises a pair of gears which convert rotational motion into linear motion. This combination of Rack gears and Spur gears are generally known as “Rack and Pinion”. Rack and pinion combinations are often used within a simple linear actuator, where in fact the rotation of a shaft powered by hand or by a motor is converted to linear motion.
For customer’s that want a more accurate motion than common rack and pinion combinations can’t provide, our Anti-backlash spur gears are available to be used as pinion gears with our Rack Gears.
Racks are portions of a cylindrical disk with an infinite radius which includes involute shaped tooth cut into its face. Racks mate specifically with spur gears that have the same module, pressure angle and preferably face width. Ever-Power offers gear racks in many components, configurations, modules and lengths. One unique feature of our racks can be that most are given finished ends. This type of production permits multiple racks to be butted, end-to-end, to create one continuous length of rack. Most of the products that we offer allow for secondary operations such as reduction of the space, the adding of tapped holes, or the use of heat treatment. Our offering also contains products that have already had a few of these secondary operations completed. These products are Stainless Steel Gear Rack recognized by a “J” within their part number plus they are offered within 10 calendar days.
