Tamiya 70246 Low-Profile Ball Casters (2pcs) - Compact STEM Series Parts for Micro Projects  [70246]

Low-profile mobility parts: Tamiya 70246 ball casters

The Tamiya Low-Profile Ball Casters are made to give lightweight models smooth movement while keeping the center of gravity low. They are a good match for small remote control builds and compact STEM projects that require tidy, unobtrusive support.

Compact layout and rolling elements

This iteration sits lower than Tamiya 70144, offering a neater fit on slim frames. The unit secures a 13/32 inch (about 10.3mm) grey steel ball with four retaining hooks to allow steady rolling. The POM plastic parts reduce friction for smoother travel on flat surfaces.

Mounting options and what's in the kit

You can fasten the casters to a universal plate with a single screw, or attach them with double-sided tape for temporary setups. The package contains 5mm spacers, L-shaped bracket components and the screws and nuts needed to get the assembly fitted quickly.
