When the rack-and-pinion is in a power-steering system, the rack has a slightly different design.
Area of the rack contains a cylinder with a piston in the middle. The piston is connected to the rack. There are two fluid ports, one on either aspect of the piston. Providing higher-pressure fluid to one part of the piston forces the piston to go, which in turn moves the rack, offering the power assist.
Roof Racks fasten to vehicles with factory installed raised railings, rain gutters, predetermined fixed points, soft rooflines and roof gear rack for railway axle mounted slotted tracks. Various crossbar lengths are available to accomodate just about any load width. Roof rack attachments are available to carry bicycles, kayaks, canoes, SUPs, surfboards, skis, snowboards and a number of other sports equipment.

Gear racks are used to convert rotating motion into linear movement. A gear rack has straight tooth 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, equipment rack and pinion are collectively called “rack and pinion”. There are various ways to use gears.
To provide many variants of rack and pinion, Ever-Power has many types of equipment racks in share. If the application takes a long duration requiring multiple equipment racks in series, we have racks with the tooth forms properly configured at the ends. These are described as “gear racks with machined ends”. When a gear rack is created, the tooth cutting procedure and the heat treatment process can cause it to try & go out of true. We are able to control this with unique presses & remedial processes.
There are applications where the gear rack is stationary, while the pinion traverses and others where the pinion rotates on a fixed axis while the 
gear rack moves. The former is used broadly in conveying systems as the latter can be used in extrusion systems and lifting/lowering applications.
