Product Description

This Martin gear rack is 2' in length and is used with a spur gear pinion to convert rotary motion into linear motion. It is made of high alloy steel for strength and durability. The 20-degree pressure angle (PA) provides a lower contact ratio between gears than a 14.5-degree pressure angle. The rack length is sized for up to 2' of linear movement and meets American Gear Manufacturing Association (AGMA) standards 6-8 for commercial class gears. This gear rack is intended for use with matching pinion gears with the same pressure angle, number of teeth, and diametral pitch (number of teeth per inch). It is suitable for use in a variety of commercial and industrial applications, such as machine tool tables, lift mechanisms, guide mechanisms, and shakers, among others.

Rack and pinion gears are made of a small round spur gear (the pinion) and a flat bar with evenly spaced teeth (the rack). Rack and pinion gears convert rotational motion into linear motion. As the pinion turns, its teeth mesh with the rack’s teeth to move it in a straight line. Gears are available in a variety of materials, including stainless steel, cast iron, brass, and plastic, depending on application. There are several other factors to consider when selecting the appropriate gear for an application. The gear’s outside diameter is the longest linear distance across a gear. The bore diameter is the distance across the hole located in the center of a gear, where the mounting shaft will be inserted. The hub diameter is the distance from one tip of the shoulder (the hub) to the other. The thickness is the distance measured from the tip of a gear tooth to the gear’s bore or base (for a gear rack). The number of the teeth refers to the number of teeth around a gear. The pitch, also called the diametral pitch, is the number of teeth divided by the pitch diameter, and it can also serve as a guide for tooth size. Rack and pinion gears are commonly used in automotive steering, meat processing, and rack railways, among other applications.

Martin Sprocket & Gear manufactures power transmission products, material handling components, and industrial hand tools. The company, founded in 1951 and headquartered in Arlington, TX, meets International Organization for Standardization (ISO) standard 9001:2008.
