The SK12 12mm Linear Rail Shaft Support Bracket is a heavy-duty aluminum block designed to hold 12mm smooth rods and optical axes firmly in place. Featuring a precise split-clamp design with an integrated locking screw, it provides a secure, non-slip grip. With its rigid dimensions (42mm base length, 38mm total height) and dual M5 mounting holes, it is a crucial component for high-precision 3D printers, DIY CNC routers, and medium-duty linear guidance mechanisms.
Full Product Description
The SK12 12mm Linear Rail Shaft Support Bracket is a precision-engineered hardware block designed to rigidly anchor and support standard 12mm linear shafts, smooth rods, or optical axes. Engineered to ensure accurate axial alignment and reduce mechanical vibrations, this support block acts as a robust foundation for medium-duty multi-axis guide structures. It utilizes a split-clamp design equipped with a top-mounted tightening screw, allowing you to lock down the guide rod with a strong, uniform grip that eliminates axial rotation and lateral slippage under load.
Constructed from high-grade cast aluminum alloy, the bracket offers excellent structural strength while remaining highly resistant to corrosion and surface oxidation. The base is precision-machined flat to guarantee perfect perpendicularity between your mounting surface and the linear shaft, preventing axis binding during high-speed travel. Its standardized, medium-duty footprint makes it a universal component for desktop fabrication tools requiring exceptionally smooth linear travel, including custom 3D printers, CNC routers, laser engravers, and automated robotic systems.
Key Product Features
- Rigid Clamping System: Built with an integrated pinch bolt that clamps securely around the 12mm rod, preventing linear drift or wobbling during intense mechanical movements.
- Anodized Aluminum Body: Premium sandblasted finish provides high wear resistance and protects the component against harsh workshop elements and friction.
- Precision Centerline Alignment: Offers a fixed 23mm center height from the mounting base to the shaft hole, maintaining parallel consistency across dual-rail configurations.
- Standardized Base Mounting: Flanged base features dual oval holes sized for M5 bolts, making it exceptionally easy to secure onto standard aluminum extrusions, T-slot profiles, or flat plates.
- High Efficiency Compatibility: Universally fits any hard or soft 12mm round shafts, chrome-plated rods, hardened steel linear guides, and carbon fiber tubes.
