How the Roller Gear Index Drive Works
Roller Gear Index Drives with Shaft or Flange are high-precision rotary indexing components, engineered for industrial automation, machining, and precision assembly. They combine roller gear technology with optional shaft or flange mounts, offering flexible installation and reliable positioning for diverse industrial applications.
Crafted with hardened steel gears and precision bearings, these drives deliver smooth, repeatable performance, withstand heavy loads, and adapt to continuous or intermittent operation.
Suitable for industries from automotive and electronics to packaging and aerospace, they eliminate positioning errors, streamline production workflows, and work seamlessly with servo motors to meet strict precision requirements.
Key parameters
Why Machine Builders Specify It
Distinct advantages over standard index drives and competing products.
Superior Repeatability & Low Backlash

Six mounting orientations
The same frame can be bolted base-down, wall mounted or inverted, and the motor can sit above, behind or in line. Quote the code with your order so the unit ships with the oil level and breather set for that orientation.
Base down, output up
Standard dial-table orientation.
Base down, output side
Right-angle output for wheel drives.
Wall mount, output horizontal
Saves floor space on narrow frames.
Inverted, output down
Overhead carrier and gantry work.
Motor top-mounted
Gearmotor stacked over the housing.
Motor rear-mounted
In-line drive for shallow installations.
Installation & Maintenance Guidelines
Proper installation and maintenance are critical to maximizing performance and service life. Follow these guidelines to keep your roller gear index drive running at full precision.
What happens next
Choose Mount & Prepare Surface
Select the shaft or flange mount that suits your equipment. The mounting surface must be flat, clean, and level, with a parallelism tolerance of ≤0.01 mm.
Secure & Align
Fix the drive firmly to prevent vibration, and align the input shaft with the motor to avoid backlash.
Connect Control System
Connect to the control system following the manual, making sure all wiring is correct.
Lubricate Every 6 Months
Check lubrication every 6 months and add the recommended industrial lubricant. Avoid incompatible oils.
Inspect & Clean
Regularly inspect gears and bearings for wear or debris, and clean them with a soft cloth.
Avoid Overload & Troubleshoot
Do not exceed rated torque or speed, as this causes precision loss. If you hear abnormal noise or see positioning issues, stop and check for loose connections or wear.

Industries That Use Roller Gear Index Drives
These roller gear index drives are ideal wherever precise, reliable rotary indexing with flexible mounting is needed. In automotive manufacturing, they position components for welding, drilling, and assembly of engine parts and body panels. In electronics production, they handle circuit board assembly and component testing with accurate alignment. In packaging machinery, they adjust product orientation for labeling, filling, and sealing, reducing defects. In aerospace, they support precision machining of small, high-tolerance components. They also excel in medical device manufacturing, positioning parts for assembly and sterilization to meet strict industry standards. Their shaft or flange options make them easy to integrate into new lines or retrofit into existing equipment, for both light-duty and heavy-duty needs.
