Frequently Asked Questions

No. This list includes both physical mechanical components, like steel helical gears and racks, and educational books on gear design and analysis. Always check the product type before purchasing.
High-quality industrial gears are typically made from 45# steel or similar alloy steels for durability. Ensure the gear has the correct hardness and heat treatment for your load requirements.
Match the module (e.g., 1M, 1.5M) and tooth count (e.g., 12T, 18T) to your existing machinery specifications. Incorrect module sizing will prevent proper meshing with the mating gear or rack.
