Advanced Engineering Analysis: TRIQUENCH SFU 2005 Precision Ball Nut | 20mm BG Series
Brand: TriQuench India | Model: SFU - 2005 BG | Classification: CNC Router Accessories > Ball Screw > Ball Screw
The TRIQUENCH SFU 2005 BG is a high-performance ball nut designed to operate as the primary linear interface in 20mm ball screw systems. Featuring a 5mm lead (pitch), this nut is optimized for applications requiring a balance of high torque transmission and fine positioning resolution. The BG series utilizes advanced internal circulation technology and precision-ground helical tracks to ensure the rolling balls transition smoothly, drastically reducing mechanical noise and frictional resistance. Forged from high-grade hardened steel, this nut maintains exceptional axial rigidity under load, minimizing backlash and ensuring repeatable accuracy during complex CNC machining cycles. Its integrated wiping seals prevent the ingress of dust and debris, making it a reliable choice for the demanding environments of industrial routers, milling machines, and automated actuators.
Technical Core: Rated for industrial-grade output, maximum rotational velocity of high-performance, operating voltage of 220V/380V, with Water/Air Cooled thermal stabilization.
Key Engineering Features: High positioning precision optimized for industrial CNC systems; Low-friction internal circulation for ultra-smooth motion transmission; Robust 20mm diameter frame with a versatile 5mm pitch; Hardened bearing steel construction for long-lasting mechanical performance; Integrated dust seals to protect internal ball tracks from debris; Zero-backlash potential when paired with precision-ground screws.
Key Machine Applications: CNC Router X, Y, and Z Axis Drive Units, Precision Milling and Lathe Tool Carriers, Automated Packaging and Material Handling Systems, Linear Stage Actuators and Positioning Tables, High-Accuracy 3D Printing and Laser Gantry Systems, Industrial Laboratory and Metrology Equipment.
