BOLTTE 45 Steel Helical Gears — Module 1, 1.5 and 2

45 steel helical gears for compatible cross-axis mechanical transmission, automation and motion-control assemblies. Select the exact module, tooth count, bore and keyway shown in the model drawing.

Model Selection

Module 1: 13, 15, 20, 26 or 30 teeth with the listed bore options.
Module 1.5: 13, 15, 20, 26 or 30 teeth with bore and keyway options shown.
Module 2: 15 teeth with the listed bore and keyway options.
Each model image retains the applicable step, overall thickness, tooth thickness and outside diameter.

Material and Use

45 steel gear body with helical-tooth geometry for compatible cross-axis arrangements.
Use only with a matching module, tooth count, shaft diameter, keyway, centre distance and load rating.
Dimensions and technical callouts are shown in millimetres unless marked otherwise.

45 steel helical gears: specify more than the module

The listed modules 1, 1.5 and 2 contain different tooth-count and bore choices. Use the exact selector entry and engineering drawing to define the gear, not the material name alone.

Selection detail	What to check
Module 1 / 13T / Bore 6 mm	An example of the module, tooth count and bore information needed together.
Keyway options	Confirm the selected keyway dimensions and shaft fit instead of assuming every bore is keyed.
Mating gear	Check helix geometry, shaft arrangement, centre distance and the required ratio.

Can a steel gear directly replace a nylon helical gear?

Not from a matching module alone. Confirm geometry, alignment, load, speed and lubrication for the complete gear pair before substituting material.

Related selection references

Compare the drawings and intended function; these references are not a statement of direct interchangeability.

Before Ordering

Confirm the module, tooth count, bore diameter, keyway size, mating gear, rotation direction, clearance, speed, torque, lubrication and operating temperature against the selected drawing. If machining is required, state the shaft diameter and whether a through bore is needed in the order notes.
