Worm Shaft & Worm Wheel Sets

A matched worm shaft and worm wheel set is the preferred enquiry format when contact, backlash, ratio, center distance, material pairing or wear condition cannot be separated safely between the two members. Reviewing both parts together also helps with replacement projects where the original tooth data are incomplete.Provide both drawings or both samples when possible. State which member must remain interchangeable with the existing machine, and identify any assembly-level contact or backlash requirement that must be verified as a pair.
