Racks are portions of a cylindrical disk with an infinite radius which includes involute shaped the teeth cut into its encounter. Racks mate exclusively with spur gears that have the same module, pressure position and preferably encounter width. EVER-POWER offers equipment racks in many materials, configurations, modules and lengths. One unique feature of our racks is certainly that most are given finished ends. This kind of production permits multiple racks to end up being butted, end-to-end, to produce one continuous amount of rack. Most of the products that people offer enable secondary functions such as for example reduction of the length, the adding of tapped holes, or the application of heat therapy. Our offering also includes products which have already had some of these secondary procedures completed. The products are discovered by a “J” within their part number and they are obtainable within 10 calendar days.
The straight tooth cylindrical gear that the radius of the pitch cylinder is infinite and in a bar form is named a gear rack. If it’s sorted by the positions of the gear shafts, it is one of the parallel shaft category. The spur equipment that meshes with a equipment rack is generally called a pinion.
Besides equipment racks with straight series teeth, there are helical racks which have slanted the teeth. Helical equipment racks are paired with helical gears, but because of the slant of the tooth path, as in helical gears, the mesh produces axial thrust forces.
Among the apparatus racks’ main applications are machine equipment and transport devices and when the applications involve transmitting linear motions, they are generally weighed against ball screws. In those instances, the main benefits of gear racks could be named such as having the ability to meet a heavier load by using larger modules and having no length limitation by connecting equipment racks with completed ends. On the other hand, an example of the disadvantages of gear racks contains the occurrence of backlash.
When manufacturing equipment racks, because of their bar shape, bending often outcomes. In such cases, corrective processes using presses are often employed.
As for the form of gear racks, aside from the usual bar form, there are circular racks where the cross sections are circular and flexible racks which may be bent into totally free curve shapes.
Racks Categories
EVER-POWER share racks are created for high precision linear motion applications. You can expect a large collection of racks which range from module 0.5 to 10 and lengths from 100 to 2000 mm.
Hardened Surface Racks (MRGF – MRGFD)
Has the highest power and precision in the EVER-POWER regular rack series. Bolt holes can be remachined as carburizing can be applied only within the tooth area. J Series items are also available.
Hardened Surface Racks (KRGF-H – KRGFD-H)
Heat treated ground gears with high precision and power has exceptional cost-performance ratio. J Series items are also available.
Steel Racks (SR)
Low cost, large selections of modules and amount of teeth. J Series items are also available.
STAINLESS Racks (SUR·SURF·SURFD)
Ideal for food machinery due to SUS304 material\’s rust-resistant quality.
Brass Racks (BSR)
Small pitch racks manufactured from free-cutting brass, excellent workability and high rust resistance.

Gear racks
Gear racks are utilized to convert rotating motion into linear movement. A gear rack has straight the teeth cut into one surface area of a sq . or round section of rod and operates with a pinion, which is certainly a small cylindrical gear meshing with the gear rack. Generally, gear rack and pinion are collectively called “rack and pinion”. There are numerous methods to use gears. For instance, as proven in the picture, a gear is used with the gear rack to rotate a parallel shaft.
To provide many variants of rack and pinion, Ever-power has many types of equipment racks in stock. If the application takes a long length requiring multiple gear racks in series, we’ve racks with the tooth forms properly configured at the ends. They are described as “gear racks with machined ends”. When a gear rack is produced, the tooth cutting process and heat treatment process could cause it to try & walk out true. We can control this with particular presses & remedial processes.
There are applications where in fact the gear rack is stationary, while the pinion traverses and others where the pinion rotates on a fixed axis as the gear rack moves. The former is used widely in conveying systems as the latter can be used in extrusion systems and lifting/lowering applications.
As a mechanical element to transfer rotary into linear movement, gear racks are often compared to ball screws. There are pros and cons for using racks in place of ball screws. The advantages of a gear rack are its mechanical simplicity, large load carrying capacity, no limit to the space, etc. One disadvantage though may be the backlash. The benefits of a ball screw are the high precision and lower backlash while its shortcomings are the limit in length due to deflection.
Rack and pinions are used for lifting mechanisms (vertical movement), horizontal motion, positioning mechanisms, stoppers and also to permit the synchronous rotation of several shafts in general industrial machinery. On the other hand, they are also used in steering systems to improve the direction of cars. The features of rack and pinion systems in steering are the following: simple framework, high rigidity, little and lightweight, and exceptional responsiveness. With this mechanism, the pinion, installed to the steering shaft, can be meshed with a steering rack to transmit rotary movement laterlly (converting it to linear movement) to ensure that you can control the wheel. Furthermore, rack and pinions are used for several other purposes, such as playthings and lateral slide gates.

Gear rack, when used with spur gears, converts rotary motion into linear motion. Equipment rack from Ever-power is designed to operate with our stock 14 1/2° and 20° PA spur gears.
Often, equipment rack is modified to match specific applications. This may include drilling and tapping mounting holes, cutting to particular lengths or coordinating ends of two bits of rack to make a continuous size longer than stock.
· Ever-power’s gear rack comes in 14 1/2° and 20° PA to suit an array of application requirements.
· Stocked in 4ft and 6ft lengths
· The choice of 48 to 3 DP meets an similarly diverse array of needs.
· Length tolerance allows ends to be matched for easy modification.
· Our in-share inventory of nylon, and metal ensures availability – and compatibility.
· Because it is perfectly matched to Ever-power’s spur gears, our gear rack promises superior functionality.
