KSUW2.5-R1J17 is a stainless steel worm with module 2.5, 1 start, and a 17 mm bore, featuring a right-hand helix angle of 3°52' and a standard full-depth tooth form with a normal pressure angle of 14°30'. The worm is made of SUS303 stainless steel with a tooth hardness of less than 187 HB, and includes a keyway of 5 mm width by 2.3 mm depth with an M4 set screw. The total length is 63 mm, and the weight is 0.36 kg. The helix angle and dimensions are defined for the J Series, which is available on request with a lead time of up to five working days.
Module 2.5, 1 Start Stainless Steel Worm with 17mm 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.
