The KSUW2.5-R2J16 is a stainless steel worm gear with module 2.5, two starts, and a 16 mm finished bore. It has a helix angle of 7°46′, right-hand thread, and is paired with a plastic worm wheel made of MC901 nylon. The worm has a pitch diameter of 50.46 mm, outside diameter of 57.5 mm, face width of 22 mm, hub width of 14 mm, and total length of 36 mm. The keyway is 5 mm wide by 2.3 mm deep, with an M4 set screw, and the weight is 0.37 kg. The precision grade is KHK W 002 grade 5. The normal pressure angle is 20°. The product produces axial thrust forces and requires lubrication if operating above the bracketed allowable torque values.
Module 2.5, 2 Start Stainless Steel Worm 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.
