Steel Worm Gear and Worm Shaft Sets — Module 1–5, 15–100 Teeth
Required Machining Notes
Please add all machining requirements to the order notes before checkout.
- Worm gear: state whether the center bore should be machined or left unmachined. If machining is required, provide the exact bore diameter, tolerance, keyway width and depth, hub requirements, and any tapped or locating holes.
- Worm shaft: provide the required shaft diameter, overall length, end diameters and lengths, thread or keyway details, and state whether an axial hole or cross hole is required. For every required hole, specify the exact diameter, depth, position, tolerance and thread specification (if applicable).
- Special requirements: include the quantity for each specification and contact BOLTTE with a drawing when critical tolerances, heat treatment, surface treatment, or other custom machining is required.
If no machining is required, write “No machining required” in the order notes. Contact BOLTTE before ordering if any dimension is uncertain.

Quick Model Finder
- Module 1: 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 70, 80 or 100 teeth.
- Modules 1.5, 2, 2.5, 3 and 4: 20, 25, 30, 35, 40, 45, 50, 55 or 60 teeth.
- Module 5: 20, 25, 30, 40 or 50 teeth.
- Choose the complete model, then confirm the gear dimensions, worm-shaft dimensions and theoretical center distance shown in its selected drawing.
Selection Notes
Module and tooth count determine the model family. Mating geometry, bore machining, keyway requirements, shaft support, lubrication and installation tolerances must be confirmed for the final assembly.
Suitable for
- Mechanical transmission systems
- Industrial automation and machinery
- Prototype and custom equipment assemblies
Before Use
Confirm the complete model, selected drawing, module, tooth count, center distance, bore and keyway machining, rotation direction, ratio, load, speed, lubrication and operating environment before installation. No lifting-safety, food-contact, medical or regulatory certification is claimed.
