The Most Common Gears for Many Jobs
These Stainless Steel Spur Gears are the most widely used gear type. They transfer power between parallel shafts and are suitable for many applications-from general machinery to high-precision systems. Yancheng Botu Transmission Machinery manufactures straight and helical cylindrical gears using 20CrMnTi, 40Cr, or 42CrMo steel. We can produce hobbed, shaved, or ground gears to match different accuracy requirements. A reliable set ofStainless Steel Spur Gears works efficiently across many tasks.
Choose Your Accuracy and Material
We offer flexible options to meet your needs:
● Hobbing: DIN 8–9 grade accuracy, cost-effective.
● Shaving: DIN 7–8 grade accuracy, smoother engagement.
● Grinding: DIN 6–7 grade accuracy, highest precision.
For material:
● 20CrMnTi with carburizing and quenching gives high wear resistance.
● 40Cr with tempering gives high toughness.
We also provide gear tooth modification to reduce engagement shock and noise. TheseStainless Steel Spur Gears give you the flexibility to match your application precisely.
Our Equipment for Accuracy and Cost Optimization
We use full CNC equipment, including CNC gear hobbing, shaving, and grinding machines. We recommend the best process based on your accuracy and cost requirements. Orders start at 50 pieces, and we support mixed orders-different modules, tooth counts, and materials in a single MOQ. Every gear undergoes careful inspection, including ball size, normal length, and tooth run-out. No part that fails inspection leaves our factory.
