Large Size Substrate Turning with the RollerDrive

When large, heavy substrates need to be rotated with precision, the drivetrain matters just as much as the structure supporting it. That’s where Sankyo Automation’s RollerDrive stands apart.

Designed specifically for demanding rotary applications, the RollerDrive delivers smooth, controlled motion—even under high thrust loads—without the compromises typically associated with large-format turning systems.

Zero-Backlash Performance for Large Substrates

At the core of the RollerDrive is a zero-backlash roller drive mechanism. Unlike traditional gear-driven systems, there is no play in the drivetrain. The result is exceptionally smooth rotation with no motion disturbances, even when handling oversized or heavy substrates.

This zero-backlash design directly translates to:

• Shorter positioning times

• Improved repeatability

• Consistent motion accuracy under load

For applications where precision and cycle time both matter, eliminating backlash is a major advantage.

Built to Handle Heavy Thrust Loads

Large substrates often bring significant axial and radial forces with them. The RollerDrive is engineered to bear heavy thrust loads, allowing fixtures to be mounted directly to the unit without additional support structures.

This capability simplifies system design and reduces stack-up complexity—especially important in automated or high-precision environments where rigidity and alignment are critical.

Improved Settling Time, Easier Integration

Because the RollerDrive operates without backlash or motion shock, systems achieve faster settling times after indexing or positioning. That means less waiting, smoother transitions, and more predictable motion behavior.

From an integration standpoint, the RollerDrive is also designed to be easy to incorporate into new or existing systems, making it a practical choice for engineers looking to upgrade performance without overcomplicating the build.

Key Benefits at a Glance

• Zero-backlash roller drive for smooth, disturbance-free motion

• Shorter positioning and settling times

• Designed for heavy thrust loads

• Fixtures can be mounted directly to the drive

• Simplified integration into precision rotary systems

Model Highlight: RollerDrive

For applications involving large size substrate turning, the RollerDrive offers a robust, precision-focused solution that combines rigidity, accuracy, and efficiency—without the drawbacks of conventional rotary drive systems.

If your application demands smooth motion, fast positioning, and reliable performance under load, the RollerDrive is built to deliver.
