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.

Brass Worm Gears and 45 Steel Worms — Modules 0.5 and 0.8

Small-module brass worm gears and 45 steel worm or worm-shaft options for compact mechanical transmission projects. Select the exact component and model required by your design.

Quick Model Finder

  • Module 0.5 brass gears: 20, 25, 30, 35, 40, 50 or 60 teeth, with model-specific bore sizes.
  • Module 0.8 brass gears: 20, 25, 30, 35, 40, 50 or 60 teeth, with model-specific bore sizes.
  • 45 steel worms: Type A and Type B options for modules 0.5 and 0.8.
  • 45 steel worm shafts: Type L options for modules 0.5 and 0.8.
  • Use the selected model image to confirm all shown diameters, widths and lengths before ordering.

Selection Notes

Worm gear and worm module must match. Confirm tooth count, bore, shaft support, mounting, direction, ratio, backlash, lubrication and installation tolerances for the final assembly.

Suitable for

  • Compact mechanical transmission systems
  • Industrial automation and machinery
  • Prototype and custom equipment assemblies

Before Use

Confirm the complete model, selected drawing, module, tooth count, bore or shaft dimensions, machining requirements, ratio, load, speed, lubrication and operating environment before installation. No lifting-safety, food-contact, medical or regulatory certification is claimed.
