Description
Product Overview
The Worm Gear Set 1.5M-20T is engineered for precision and durability, offering a 20:1 reduction ratio that is essential for applications requiring reliable speed control and torque conversion. Constructed with a hardened 45# carbon steel rod shaft, the shaft provides exceptional strength and wear resistance, while the accompanying brass gear ensures smooth meshing and quiet operation. The set includes a 15 mm bore rod shaft and a matching brass gear wheel ranging from 8 mm to 15 mm in diameter, giving you flexibility to match a variety of motor shafts. The center distance for the 1:20 configuration is precisely 27.50 mm, guaranteeing consistent performance across the entire product line. Designed for industrial robot spare parts and small motor deceleration, this gear set delivers the reliability needed in demanding environments.

FAQ
What is the maximum torque this gear set can handle?
The gear set is designed for moderate torque applications typical of small to medium industrial robots. Specific torque limits depend on the exact motor and load conditions, but the carbon steel shaft and brass gear are rated for up to 15 Nm in continuous operation.
Can I use this gear set with a motor shaft larger than 15 mm?
The supplied rod shaft is available in sizes up to 15 mm bore. For larger shafts, a custom adapter or a different BSTAUTOMATION product line would be required to ensure proper fit and performance.
Is the gear set suitable for high‑speed applications?
While the worm gear design excels at reducing speed and increasing torque, it is not intended for extremely high‑speed scenarios. It performs best in applications where speed reduction and precise control are more critical than maximum rotational speed.
How do I install the gear set?
Installation is straightforward: insert the rod shaft into the motor shaft bore, align the brass gear with the worm, and secure both components using the provided set screws. Detailed torque specifications are included in the user manual.
What warranty does BSTAUTOMATION provide?
All worm gear sets come with a one‑year limited warranty covering manufacturing defects. Our customer service team is ready to assist with any issues that arise during the warranty period.
