These 8mm miniature bearings are made of high quality bearing steel for low noise and long service life. They are double shielded to avoid contaminants entering and save lubricant. Used with 8mm ACME rod and the 8mm smooth rod. 

This solid aluminium component functions as a right-angle structural connector or an adjustable wheel block for 20mm V-Slot rails and standard 2020 profiles. It establishes perpendicular joints using low-profile fastening routes, eliminating the need for secondary brackets. Typical applications include constructing rigid frame joints, structural reinforcements, and gantry wheel blocks within 3D printer frames, CNC machinery, motion tracking setups, and automation enclosures. The block also serves as a direct mounting interface for attaching peripheral devices to the framework.

This solid clear polycarbonate roller assembly mounts onto gantry carriage plates, rolling along structural extrusion channels to establish a low-friction tracking interface. The un-recessed, self-assembled configuration resists material compression under load, allowing multiple components to distribute mechanical forces evenly to maintain axis tolerances. Engineered for positioning stages subjected to dynamic forces and high load cycles, the assembly utilises high Rockwell hardness and compressive strength to prevent alignment drift without introducing play. Typical applications include the construction of modular CNC routers, milling machines, automated machinery platforms, and industrial actuator setups incorporating belt-and-pinion or timing belt drives.
