R20-10T3 FSI Precision Rolled Ball Screw | 20mm Diameter

The R20-10T3 FSI is a precision-engineered rolled ball screw designed for industrial applications that require a balance of high-speed travel and surgical accuracy. Featuring a 20mm shaft diameter and a 10mm pitch, this ball screw is capable of rapid linear positioning, making it ideal for the primary axes of high-speed CNC routers and automated systems. The 'FSI' designation identifies its specialized single-nut design, which incorporates an internal circulation system for smooth ball return and minimized friction. With 'T3' turns of the ball track, it provides high axial rigidity and a stable load-carrying capacity while maintaining a compact footprint. Manufactured from high-grade hardened steel, this right-hand thread ball screw ensures long-term durability and repeatable performance in demanding production environments where precision linear motion is critical.

Technical FAQ & Operational Guide

What does the 10mm pitch mean for my CNC's speed?

The 10mm pitch means the nut travels 10mm for every full 360° rotation of the screw. Compared to a standard 5mm pitch, this allows for double the linear speed at the same motor RPM, making it ideal for the X and Y travel axes.

Is the FSI nut interchangeable with standard SFU nuts?

While the diameter and pitch are the same, FSI nuts often have different mounting hole patterns or flange dimensions compared to SFU nuts. Always check the technical drawing before attempting a replacement to ensure bolt-hole alignment.

How should I maintain this ball screw to ensure longevity?

Regular lubrication is essential. We recommend using a high-quality lithium-based grease via the nut's grease port every 100km of travel. Additionally, keep the screw clean of wood chips or metal dust to prevent ball track wear.

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.
