Tamiya 70144 Ball Caster Set (2 pcs) - Classroom and Hobby Kit  [70144]

Add a Free-Roll Pivot to Your Model

The Tamiya 70144 Ball Caster gives hobbyists a low-profile pivot that enables smooth side-to-side movement for lightweight robots and teaching rigs. It provides a simple, compact way to reduce friction where a fixed wheel would bind during turns.

Fine Tuning with Height Adjustment

Adjustable mounting height lets you set how the caster contacts the surface, so you can dial in tracking and reduce nose or tail lift. This flexibility helps when switching between different floor types during experimentation.

Simple Integration With Kits

These casters pair well with a wide range of Tamiya construction kits and basic chassis designs. Supplied as a pair, they give you options for placement and help stabilise small mobile platforms used in lessons or at the bench.
