AGV and automated-cart casters run continuous duty, so a replacement must match the original spec exactly: dynamic load rating, wheel material, diameter, bearing type, and overall height. A close-enough caster wears out fast under sustained revolutions and can throw off navigation or docking. And because a down AGV stops automated flow, the replacement has to be fast as well as exact.
CasterHQ supplies and cross-references AGV casters for automation integrators. Here is what has to match and why speed matters.
Why AGV replacement is different
Continuous duty and dynamic loads change the rules. An AGV running multiple shifts generates more wheel revolutions in a month than a manual cart sees in a year, and acceleration, braking, and turning add dynamic forces a static rating does not capture. General-purpose casters that survive on a hand cart fail quickly here. For the wheel-material side of this, see our AGV wheel selection guide.
The specs that must match
- Dynamic load rating — match the rated rolling load, not just static capacity.
- Wheel material — typically polyurethane on a metal core for wear resistance and low rolling resistance.
- Diameter — affects rolling effort and ride height.
- Bearing type — precision bearings for smooth, repeatable motion.
- Overall height — must be exact for navigation and docking.
Matching the exact replacement
Cross-reference the full spec, not just the footprint. The safest path is to record the original caster once and reorder that exact part. Our guide on measuring a caster for replacement covers what to capture.
Why speed matters on automation
A down AGV halts automated flow, so the reorder window is downtime. Pre-mapping the exact part and reordering by scan removes the identify-and-source delay that makes an automation stop expensive. See the cost of caster downtime for the math.
Tagging AGVs for fast reorder
CasterHQ FleetTag maps each AGV and automated cart to its exact replacement caster and puts a scannable tag on the unit, so the team reorders the correct part in seconds. Free for qualified manufacturing partners.
- AGV casters must match dynamic load, material, diameter, bearing, and height exactly.
- Polyurethane on a metal core is the standard AGV wheel.
- Overall height is critical for navigation and docking.
- A down AGV stops automated flow, so reorder speed drives cost.
- FleetTag tags each unit for fast, exact reordering.

Frequently Asked Questions
Why are AGV caster replacements different from manual carts?
AGVs run continuous duty and generate far more wheel revolutions, with dynamic loads during acceleration, braking, and turns. Replacements must match the original dynamic rating and material exactly or they wear out fast and can throw off navigation.
What wheel material is best for AGVs?
Polyurethane on a metal core is the standard for AGVs and automated carts: wear-resistant, non-marking, low rolling resistance, and floor-friendly on epoxy and sealed concrete.
Does caster height matter on an AGV?
Yes, critically. AGV navigation and docking depend on consistent ride height, so a replacement must match the original overall height precisely across all positions.
How fast do AGV caster replacements need to happen?
Fast. A down AGV stops automated flow, so the replacement window directly drives downtime cost. Pre-mapping the exact part and reordering by scan removes the delay.
Can I use a standard caster to replace an AGV caster?
Only if it matches the original dynamic load rating, material, diameter, bearing type, and height. Substituting a general-purpose caster usually fails early under continuous duty.
How does CasterHQ support AGV fleets?
We cross-reference the exact AGV caster and can tag each unit with FleetTag so the team reorders the correct part by scanning, free for qualified partners.
