It is a multi-lead worm gear that allows for any backlash when moved in the axial direction. The pitch accuracy is grade 1.

To adjust the backlash of a worm gear, it is common to change the assembly distance, which previously required extensive modifications such as working on the gear case to alter the already assembled distance. However, by using a multi-lead worm gear, it becomes possible to adjust the backlash without changing the assembly distance of the gear case, greatly improving workability and maintenance convenience. 【Features】 ○ Module 1.5 to 4 ○ High-strength, high-precision multi-lead worm Moving the worm axially allows for any desired backlash ○ Multi-lead worm wheel with first-class pitch accuracy and excellent wear resistance The wheel is made of aluminum bronze, which has excellent anti-friction properties *For more details, please contact us or refer to the catalog.
