Rail-Channel and U-Wheels

Rail-Channel

Rail-Channel is a structural component with precision rails for U-Wheels to ride on to create smooth linear motion. The central goBILDA® pattern and threaded ends provide for the simple and solid attachment of drive mechanisms. With its capacity to be driven by belts, cables, and even lead screws, Rail-Channel is a fantastic railway into versatile back-and-forth action!

U-Wheels for Rail-Channel

Polycarbonate U-Wheels are a profile-match made in heaven for Rail-Channel! The U-shaped groove around the perimeter of a U-Wheel perfectly hugs the 8mm diameter rails on the outer edges of Rail-Channel. Each wheel rotates smoothly on a pair of pressed-in bearings so that linear motion can happen with ease and efficiency. Take note of the offset of the bearings—one is flush, and the other is nested into the wheel, allowing for more options for both the height of the carriage you plan to move and the clearance of the hardware resting on the opposing side.
