Module 2 ground helical gear, left-handed, with 48 teeth, matching the KKHG2-48L series. It features a transverse pressure angle of 20°, helix angle of 21°30', and is made of SCM440 steel with induction-hardened tooth surfaces rated at 50~60 HRC. Precision conforms to JIS grade N6 (JIS B1702-1:1998) and JIS grade 2 (JIS B1702:1976). The gear has a face width of 16 mm, hub width of 13 mm, and total length of 29 mm. Backlash is specified as 0.12~0.22 mm. Axial thrust forces are produced. Bore diameter is not specified on the page for this variant, but standard bore sizes in the series range from 16 mm to 25 mm. Secondary operations on teeth are prohibited due to induction hardening.

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.
