KCG2.5-50R1J16 is a right-hand helical worm gear with a module of 2.5, 50 teeth, one start, and a 16 mm bore. It features a gray iron wheel with a 125.29 mm pitch diameter, 130 mm outside diameter, and 22 mm face width. The gear has a normal pressure angle of 20°, standard full-depth teeth, and a KHK W 002 grade 4 precision rating. The J16 variant includes a keyway of 5 mm width by 2.3 mm depth and a set screw, with a total length of 16 mm and weight of 0.37 kg. Backlash ranges from 0.13 to 0.31 mm. The allowable torque at 100 rpm is 59.0 N·m, and at 600 rpm is 40.7 N·m.
Module 2.5, 50 Tooth, 1 Start, Right Handed Cast Iron Worm Gear with 16mm 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.
