The KCG2.5-60L1J18 is a left-hand lead worm gear in the KCG module 2.5 series, featuring a 60:1 reduction ratio, 1 start, and a 15mm bore with a keyway and set screw for J-series variants. It is made of gray iron with a sand mold casting finish, has a face width of 22mm, and a pitch diameter of 150.34mm. The gear operates with a helix angle of 3°52' and follows KHK W 002 grade 4 precision standards. Allowable torque at 30 rpm is 98.8 N·m, with backlash ranging from 0.13 to 0.31 mm and a weight of 1.93 kg. J-series variants require a 5-day lead time and are available in quantities of 1 to 20 units per order.
Module 2.5, 60 Tooth, 1 Start, Left Handed Cast Iron Worm Gear with 18mm Finished Bore
A worm gear pair, or worm gear set, consists of two gears: the worm, which resembles a spiral screw, and the worm gear (aka, worm wheel).
For the pair to mesh, the worm and worm gear must have the same pressure angles, modules, and lead directions (left- or right-hand).
A worm revolves on a shaft that’s perpendicular to the worm gear and the shaft angle is typically 90°. Because the teeth gradually mesh as the worm rotates, there is low noise and low vibration.
