Worm Gear W0.3-5-6 for 1.5 mm Shafts (Module 0.3, Ø 5 × 6 mm)

The metal worm gear W0.3-5-6 is designed for fine-pitch drives with 1.5 mm shafts in model railway applications. It transfers the motor torque reliably to the mating gear and is suitable for repairs and conversions of locomotives and powered vehicles.

Dimensions:

• Module: 0.3
• Bore (inner diameter): 1.5 mm (tolerance +0.05 mm, −0 mm)
• Outer diameter: 5.0 mm
• Length: 6.0 mm

The precision-machined bore enables a play-free fit on 1.5 mm shafts. With an outer diameter of 5.0 mm and a length of 6.0 mm, the worm gear offers a stable contact area for smooth, low-vibration power transmission.

Properties and benefits of the worm gear:

• fine 0.3 module tooth profile for smooth, even running
• precision bore for 1.5 mm shafts (tolerance +0.05 mm, −0 mm)
• robust dimensions (Ø 5.0 mm, length 6.0 mm) for stable meshing
• suitable for repairs and conversions of model railway locomotives and vehicles

Together with a suitable mating gear, the worm gear ensures precise, low-vibration power transmission between the motor and the drivetrain.

Handling notes:

• Always push the worm gear straight onto the shaft without excessive force to avoid damaging the bore.
• Deburr the shaft ends slightly if necessary so the worm can be pushed on cleanly.
• Align the worm carefully to achieve the lowest possible runout and correct gear mesh.
• Secure the connection to the shaft with a fast-curing metal adhesive to reliably prevent twisting or slipping.
