SFU3205 Ball Screw C5 Kit + Nut + BK/BF25 End Support + Coupler + Housing

Product Overview

The SFU3205 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.

Complete Kit (Screw + Nut + End Supports + Coupler + Housing). This complete kit includes the precision ball screw, ball nut, a pair of BK/BF25 end supports, a drive coupler and a mounting housing, giving you everything needed to drop straight into your machine frame.

The robust 32 mm shaft diameter supports high rigidity and heavy-load applications in larger machinery. The 5 mm lead offers a well-balanced combination of positioning accuracy and travel speed, suiting most general-purpose CNC and automation applications.

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/BF25 End Support Set: Fixed (BK) and support (BF) ends included to lock the screw rigidly and eliminate end float for consistent accuracy.

• Ready-to-Install Kit: Coupler and mounting housing included, so the kit can be assembled into your machine with minimal extra parts.
