SFU 2005 Ball Screw | 1000mm High-Precision Linear Motion Assembly

The TriQuench SFU 2005-1000MM BG is a cornerstone of high-performance linear motion, specifically engineered for the rigorous demands of industrial CNC routers and automated systems. Featuring a 20mm nominal diameter and a 5mm lead (pitch), this ball screw provides the perfect equilibrium between high axial rigidity and smooth, low-friction transmission. Manufactured from premium GCr15 bearing steel and induction-hardened to HRC58-62, it ensures exceptional wear resistance and long-term repeatable accuracy. The BG series optimization utilizes advanced raceway grinding to achieve a C7 precision rating, effectively minimizing backlash and enhancing the surface finish quality of your machined parts. With its 1000mm length, this assembly is ideal for primary axis drives in medium-format CNC machines, industrial robotics, and high-precision laboratory positioning stages.

Technical FAQ

What does the 2005 designation signify?

The first two digits (20) represent the nominal diameter of the screw in millimeters, and the last two digits (05) indicate the lead or pitch, which is the linear distance the nut travels in one full revolution.

Is this ball screw suitable for vertical Z-axis applications?

Yes, the SFU 2005 offers high axial rigidity and load capacity, making it perfect for vertical axes. We recommend using a motor with a brake or a counterweight system for Z-axis applications due to the low friction coefficient.

How should I maintain my TriQuench ball screw?

Maintenance is vital for longevity. We recommend applying a lithium-based grease every 100km of travel or every 3 months. Always ensure the screw is wiped clean of debris and protected by bellows in dusty environments.
