Product Description
Custom Spur Girth Gear Overview
Girth gears are engineered for mounting on large rotating drums with diameters ranging from 1 meter to over 12 meters. Due to their substantial size, these gears are manufactured in multiple sections (typically two, four, or more) and assembled on-site for industrial applications.
Key Features & Benefits
- High load-bearing capacity for transmitting substantial torque in heavy-duty operations
- Premium wear-resistant construction ensuring robust durability and extended service life
- Minimal maintenance requirements for reduced operational downtime
- Fully customizable to specific operational demands with diverse sizing and configuration options
