Shaft End Support SF12 (Horizontal - 12mm)

Overview

Ensure rock-solid stability for your CNC machine's moving axes with the SF12 Shaft End Support. This precision-machined, anodized aluminum end support block is specifically designed to hold 12mm linear shafts firmly in place, eliminating play and vibration that compromise accuracy. Whether you're building a DIY CNC router, upgrading a 3D printer, or constructing a custom automation rig, the SF12 provides the sturdiness and alignment your project needs.

Key Features

• Precision-Machined Anodized Aluminum: Lightweight yet exceptionally strong, with a corrosion-resistant surface for long-lasting performance.
• Stable 12mm Shaft Support: Holds 12mm shafts securely to minimize deflection and maintain precise linear motion.
• Universal Compatibility: Works with all types of 12mm shafts—solid, hollow, or hardened—making it a versatile addition to any build.
• Simple Installation: Features M4 clamping bolts and M5 mounting bolts for quick, secure attachment to your machine's frame.
• Compact Design: Optimized for space-constrained setups, ensuring easy integration without sacrificing rigidity.

Applications & Use Cases

• CNC Routers & Mills: Provides essential end support for linear shafts on X, Y, and Z axes, reducing vibration and improving cut quality.
• 3D Printers: Stabilizes the Z-axis lead screws or guide rods, ensuring consistent layer heights and reducing artifacts.
• Lathes & Custom Machines: Perfect for securing shafts in custom-built equipment, from engraving machines to pick-and-place systems.
• Robotics & Automation: Ideal for linear motion systems in robotic arms, gantries, and conveyor mechanisms where precision is critical.

What's Included

• 1x SF12 Shaft End Support (Horizontal)
• Mounting hardware (M4 and M5 bolts) – please verify if included; if not, note in product images.

Compatibility

• Shafts: Any 12mm diameter shaft (linear shafts, lead screws, etc.)
• Frames: Compatible with standard aluminum extrusion (2020, 2040, etc.) and other mounting surfaces using M5 bolts.

MOKWN Recommendation

Pair the SF12 Shaft End Support with a matching 12mm linear shaft and pillow block for a complete, high-stability linear motion system. For CNC applications, we recommend using two supports per axis to ensure maximum rigidity. Whether you're a hobbyist or a professional, this support block is a must-have for your next precision project.
