TRIQUENCH SFU 2505 Ball Nut - BG Series Precision

The TRIQUENCH BALL NUT SFU - 2505 BG is an essential industrial component engineered for high-performance linear motion in CNC systems and specialized ball screw drives. Optimized for 25mm diameter shafts with a 5mm lead, this SFU series nut efficiently converts rotational torque into precise linear movement. The BG series internal ball circulation system is designed to minimize friction and heat generation, ensuring surgical accuracy even during high-duty cycles. Manufactured from hardened high-quality steel, this ball nut provides exceptional axial rigidity and durability, significantly reducing backlash and vibration. It is the standard choice for professional machine tool builders requiring reliable, low-noise motion transmission for high-accuracy fabrication and industrial automation.

Technical FAQ & Operational Guide

Does this nut include the steel balls and wiper seals?

Yes, the TriQuench SFU 2505 BG ball nut comes fully assembled with the internal ball bearings and integrated dust wiper seals to ensure smooth travel and protection from workshop debris.

Can I use this nut on a 2510 series ball screw?

No. The pitch must match. An SFU 2505 nut is specifically designed for a 5mm pitch screw. For a 10mm pitch screw, you must use an SFU 2510 series nut.

How do I maintain the SFU 2505 ball nut?

Regular lubrication is critical. The nut features a lubrication port (usually an M6 grease nipple thread). We recommend using high-quality lithium-based grease periodically to maintain low friction and prevent premature 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.
