Overview

The Adafruit 1182 is a heavy-duty aluminum support block designed to secure 8mm diameter linear motion shafts. It provides a stable, rigid mount for precision rods used in CNC machines, 3D printers, and custom robotics projects. The bracket features a side clamping screw to lock the shaft in place without damaging the surface.

Why Choose This Part

This support block is machined from solid aluminum for high rigidity and minimal flex under load. The integrated pinch-bolt mechanism ensures a secure grip on the shaft compared to simple set screws, while the standard mounting holes simplify alignment on flat surfaces.

Applications

Small Scale CNC Machines
Securing the X, Y, or Z axis guide rods to the machine frame for repeatable linear motion.
Desktop 3D Printers
Mounting the smooth rods that support the extruder carriage or the heated bed assembly.
Camera Sliders
Building DIY motorized or manual camera rails for smooth cinematographic panning.
Automated Laboratory Equipment
Providing structural support for linear actuators used in liquid handling or sample positioning systems.

Getting Started

To use this part, slide an 8mm smooth shaft into the center bore and tighten the side hex bolt to clamp it. Mount the base to your chassis using M4 or M5 screws, ensuring that two supports are perfectly parallel to prevent binding of the linear bearings.
