Precision rack and pinion: the importance of head polishing
Next time you're at the mechanic, look under the hood. Chances are, you'll see rack and pinion steering. Rack and pinion steering systems are among the most precise forms of car steering, but just because it's precise doesn't mean they can't benefit from precision work.
What are precision rack and pinion bearings?
Precision rack and pinion bearings are a type of linear bearing that uses a gear to convert rotational motion into linear motion. The gear meshes with a toothed bar or rod called a rack, which can either be fixed or movable. The gears are usually made of stainless steel for durability and precision.
What is head polishing?
Head polishing is the process of creating a smooth, shiny surface on stainless steel gears. It is done using a machine called a precision rack and pinion. The purpose of this machine is to create a polished surface that will not wear down as quickly as a non-polished surface. Head polishing can be done by hand or by using the equipment.
Stainless Steel Gears vs. Carbon Steel Gears
Stainless steel gears are more corrosion-resistant than carbon steel gears. Stainless steel gears also have a higher strength-to-weight ratio, making them ideal for applications where weight is a concern.
