Details

Built for compact robot chassis and smart cars, the 1-inch caster adds smooth 360° steering with a durable nylon wheel.

Detailed measurements help confirm clearance, mounting-hole spacing, and load rating before integrating into a chassis.



Choose the L-type 520 option when you need the included standoffs and screws for a level install on that chassis style.

The 310 motor chassis set includes shorter copper pillars to match common wheel heights and keep the chassis level.


Three copper-pillar lengths are provided across package options to match different two-wheel-drive chassis platforms.
