R20-10 Precision Rolled Ball Screw | 20mm Diameter | 10mm Lead

The R20-10 Precision Rolled Ball Screw is a core mechanical component for industrial CNC systems requiring rapid linear travel without sacrificing positioning accuracy. With a substantial 20mm shaft diameter and a high-lead 10mm pitch, this screw is optimized for high-speed axes where productivity and throughput are paramount. The rolled thread technology ensures a smooth surface finish for the ball bearings to traverse, resulting in low-friction movement and minimal thermal expansion. This specific 3000mm length is ideal for large-format router tables and automated gantry systems, providing the rigidity necessary to span long distances while maintaining surgical accuracy. Manufactured from hardened high-quality steel, the R20-10 series offers exceptional wear resistance and a high axial load capacity, ensuring reliable, maintenance-free performance in demanding industrial environments.

High-precision rolled thread for consistent linear accuracy
High-lead 10mm pitch for rapid axis movement and increased efficiency
Durable hardened steel construction for extended industrial service life
Smooth and silent transmission with minimal friction loss
Low heat generation during high-speed operations
Optimized for heavy-duty CNC router and automation applications

Technical FAQ & Operational Guide

What is the advantage of a 10mm lead over a 5mm lead?

A 10mm lead (pitch) allows the machine axis to travel 10mm for every single rotation of the motor. This provides double the linear speed compared to a 5mm lead at the same RPM, making it the superior choice for high-speed routing and rapid positioning.

Can this 3000mm screw be cut to a specific size?

Yes. While the standard stock length is 3000mm, we offer precision cutting and end-machining services to match your specific machine requirements, including standard BK/BF support block machining.

How often should the R20-10 ball screw be lubricated?

For industrial use, we recommend a high-quality lithium-based grease applied via the ball nut's grease nipple every 100-200 hours of operation. Proper lubrication is critical to preventing wear and maintaining the surgical precision of the thread.

How is the rotational balancing calibrated on this spindle motor?

Every spindle motor is dynamically balanced in accordance with the ISO 1940 balancing standard to guarantee vibration-free running and maximum stability at high RPMs.

What are the runout tolerances of the shaft and collet interface?

The internal shaft taper maintains a runout accuracy tolerance of under 0.003mm (3 microns), maintaining precise tool concentricity and preventing premature cutter wear.

What cooling precautions are built-in to prevent heat exhaustion?

Built-in temperature dissipation channels support continuous water/liquid cooling circulation or forced fan airflow, preventing thermal expansion of components.

Is this spindle motor compatible with standard VFD inverters and collets?

Yes, the spindle supports direct electrical integration with standard variable frequency drives (VFD) and accepts industrial ER collets (ER11, ER20, ER25, or ER32) to match standard toolholder dimensions.
