SFU1204 Ball Screw C5 + Nut + BK/BF10 End Support for CNC
Product Overview
The SFU1204 C5 Precision Ball Screw is manufactured using high-precision machining processes and strict quality control to deliver accurate, smooth and reliable linear motion. Its precision-ground raceways and optimized ball circulation system provide low friction, high transmission efficiency and stable positioning performance. Designed for applications requiring high positioning accuracy and repeatability, the C5 ball screw is suitable for CNC machines, automation equipment, linear motion modules, precision positioning systems and other high-performance machinery.
Screw + Nut + End Supports. This set pairs the precision ball screw and nut with a matched BK/BF10 end support set, delivering ready-to-fit rigidity and alignment without extra sourcing.
The compact 12 mm shaft diameter is well suited to light-duty machines, small linear modules and space-constrained designs. With a fine 4 mm lead, this screw delivers high positioning resolution and precise incremental feed, making it ideal for applications where accuracy matters more than speed, such as engraving, EDM and fine positioning tables.
Key Features
C5 Precision Grade: Provides high positioning accuracy and repeatability.
High Transmission Efficiency: Rolling contact minimizes friction and improves power transmission efficiency.
Smooth Operation: Precision ball circulation ensures stable and low-friction movement.
High Wear Resistance: Precision-machined raceways provide excellent durability and long service life.
Stable Positioning: Suitable for high-frequency and continuous-motion applications.
Flexible Specifications: Available in various shaft diameters, leads, lengths and nut configurations.
Complete BK/BF10 End Support Set: Fixed (BK) and support (BF) ends included to lock the screw rigidly and eliminate end float for consistent accuracy.
