Product Description
Custom Double Helical Gears for Heavy-Duty Applications
High-performance ZG 42CrMo double helical gears engineered for demanding industrial applications requiring zero thrust force and maximum power transmission efficiency.
Double Helical Gear Design
Consists of two identical gears mounted on the same axis with opposing helix directions—left-hand and right-hand—to eliminate axial thrust forces.
Key Advantages
- Zero resultant thrust force for stable operation
- High power transmission capacity
- Optimized helix angle for maximum efficiency
- Superior performance in heavy-duty applications
