A 1B 9-Y325018 is an 18-tooth, 32-diametral pitch, 20° pressure angle brass pinion wire, sold in 5-foot lengths with unfinished ends and a length tolerance of ±0.5 inch. It is part of a series available in brass and steel, with common specifications including 32 and 24 pitch options and standard lengths of 1, 3, or 5 feet. The part matches the 32 pitch, 20° pressure angle brass configuration listed for 18 teeth with an outside diameter of 0.625 inch.
The material of pinion wire is dragged through the dies; it is referred to as "drawn" steel, a process that begins with melting several metals together, typically iron plus an additional metal type that is a crucial part of the alloy (smelting). After being slightly cooled, the metal is then coated with a drawing lubricant and pulled through the dies, which form its teeth. The metal cannot be dragged through the dies that shape it without this lubrication.
When a stock gear is not available, spur gears can be made using SDP/SI pinion wires. Available in the following pitches: 64, 48, 44, 32, and 24 (modules 0.4, 0.5, and 0.8) in steel and brass. Other lengths are available upon request.
Steel spur gear stock is also offered in pitches 48, 32, 24, and 20 (modules 0.8 and 1) and is used to make spur gears.
