This is What We Do

High-Precision Gears for Industrial Applications

Spur Gears

The most common type of gear, featuring straight teeth mounted on parallel shafts. Known for simplicity, efficiency, and smooth power transmission across diverse industrial applications.

• Straight teeth, parallel shafts
• High efficiency & reliability
• Ideal for moderate speed applications

Helical Gears

Featuring angled teeth for smoother, quieter operation than spur gears. Ideal for high-speed and high-load applications where noise reduction is critical.

• Angled teeth for gradual engagement
• Reduced noise and vibration
• Higher load capacity

Herringbone Gears

Double helical design eliminates axial thrust, offering superior balance and performance in heavy-duty industrial systems.

• No axial thrust forces
• Self-aligning design
• Used in high-power transmission

Bevel Gears

Designed to transmit motion between intersecting shafts, typically at 90 degrees. Ideal for changing the direction of drive in mechanical systems.

• Transmit power at angles
• Right-angle or angular drives
• Precision tooth geometry

Worm Gear Sets

Provide high reduction ratios in compact spaces with self-locking capabilities. Ideal for applications requiring controlled motion and safety.

• High torque, low speed output
• Self-locking feature
• Compact and efficient design

Custom Other Gear

Beyond standard types, we engineer specialized gears tailored to unique industrial requirements, including internal gears, rack and pinion, and planetary systems.

• Fully custom designs
• CAD-supported engineering
• Prototyping and testing

Spur Gears for Drill Rig

Heavy-duty spur gears engineered specifically for drilling equipment, built to withstand extreme loads and harsh environments.

• High strength and durability
• Optimized for oil & gas drilling
• Precision heat-treated

Industrial Gearboxes

Complete gearbox assemblies integrating precision gears for power transmission in construction, mining, and marine applications.

• Fully assembled and tested
• Custom ratios and configurations
• Sealed for durability
