S1L86Z-P048S020 is a left-hand helical gear with 20 teeth, 48 normal pitch, 20° pressure angle, and 45° helix angle, machined from 303 stainless steel and featuring a 1/4-inch bore. The gear has a 0.5892-inch pitch diameter and 0.631-inch outside diameter, with a 3/16-inch face width and a #6-32 set screw for shaft retention. The gear is designed for use in applications requiring reduced noise and vibration compared to spur gears, and it features a sub-drill for a set screw to secure the shaft.

Helical gears are comparable to spur gears, but due to the higher contact ratio, they are quieter, vibrate less, and experience less friction. Helical gear pairs have the same helix angle but opposite threads (left-hand and right-hand). Helical gears can be used in place of spur gears; they can be used in drives with non-parallel axes or positioned in between parallel axes. Helical gears are suitable for applications involving faster speeds and larger loads because, unlike spur gears, their teeth are twisted along the helical path and progressively interlock into one another.
Helical gears can also be found in industries related to movable earth, power, and oil drilling. Because of their efficacy with heavy loads, they are found in elevators, conveyors, compressors, and blowers. The most popular helical gear application is in the automobile industry, specifically in transmissions.
Our inch and metric helical gears are offered in 48-pitch modules 1, 2, and 3.
They are available in stainless steel, aluminum, and ground-hardened steel with black oxide finishes.
