Large Girth Gear: The Backbone of Heavy Industrial Rotating Equipment

Large girth gears are among the most critical components in modern heavy industry.

They are widely used in rotary kilns, ball mills, vertical mills, dryers, and other large rotating machinery in cement, mining, metallurgy, and power generation plants.

A high-quality girth gear directly affects the stability, efficiency, and service life of the entire production line.

Compared with standard gears, large girth gears require higher precision in forging, casting, heat treatment, machining, and assembly.

In cement plants, the girth gear drives the rotary kiln to run continuously for years.

In mining sites, it withstands heavy loads, dust, and severe working conditions.

Any failure can lead to long downtime and huge economic losses.

Key features of a reliable large girth gear:

• High-strength alloy steel or cast steel material
• Stable heat treatment to ensure hardness and toughness
• High-precision gear cutting and grinding
• Good anti-wear, anti-fatigue, and shock resistance
• Easy installation, maintenance, and replacement

When choosing a large girth gear, buyers focus on material, accuracy, load capacity, manufacturer experience, and after-sales service.
