AH Series Heavy-Duty Planetary Gearbox

Frame Sizes

AH042–AH150

Gear Ratios

3:1–250:1

Heavy-Duty Design

High Torque Capacity

Needle Roller Bearings

High Radial Load Capacity

The AH Series planetary gearbox is engineered for heavy-duty applications where high torque capacity, output rigidity and load durability are required. Its robust housing and needle roller bearing structure provide reliable support for demanding radial loads while maintaining stable transmission performance.

With six frame sizes, reduction ratios from 3:1 to 250:1 and up to three reduction stages available, the AH Series provides flexible solutions for industrial machinery, material handling equipment, automation systems and other high-load motion applications.

Robust construction provides high torque capacity and reliable transmission for demanding industrial drive applications.

Needle roller bearings provide high radial load capacity in a compact structure for stable heavy-duty operation.

1-stage, 2-stage and 3-stage configurations cover ratios from 3:1 to 250:1 for speed and torque needs.

Long-life grease lubrication and durable construction support reliable operation with lower maintenance requirements.
