0.4-20 Module Custom Mill Pinion Gears From ZTIC Smooth And High Precision

Our spur and helical gears are welcomed by many customers for its stable high quality and competitive price.

The producing character of ZTIC gears:

1. Gear size: the biggest diameter is 1500mm;

2. Material: Most common steel is high strength steel 20CrMnTi. Others can be steel C45, stainless steel, high strength steel, copper, aluminium, plastic, POM etc;

3. Gear module: 0.3-8 (pitch from 0.942-25.12mm, DP 3.175-85);

4. Surface: zinc (galvanized), black, chromium plating, nickel plating, quenching and tempering etc.

5. Quality: stable and high, grade 7 for without teeth grinding, grade 6 after teeth grinding, grade 5 for precise grinding.

Prices for above quality are very competitive for us.

6. Heat treatment: teeth can be hardened to HRC 55-63.
