The Mini-Mite is the answer to a problem most casters can’t solve: the load is heavy but the vertical clearance under the load isn’t there. Aerospace fixture transfers, automotive line tooling, semiconductor wafer-handling rigs, and machinery repositioning all share the same constraint — the deck has to sit close to the floor, and somehow has to support up to 16,000 lb per caster.
Hamilton Low Profile Mini-Mite casters carry up to 16,000 lb per caster in the lowest practical overall height. Twin Nylast and Plastex phenolic wheels fit under-machine moves and restricted-clearance applications where standard heavy casters sit too tall.
| Series / Config | Size | Capacity | Wheel | Best For |
|---|---|---|---|---|
| Mini-Mite, twin Nylast | 4"–6" | up to 16,000 lb | Twin Nylast | Lowest height at high capacity, machine bases |
| Mini-Mite, Plastex phenolic | 4"–6" | up to 10,000 lb | Plastex phenolic | Under-machine moves, hard floors |
| Mini-Mite, twin Nylast, compact | 3"–4" | up to 8,000 lb | Twin Nylast | Severely restricted clearance retrofits |
| Mini-Mite, Plastex phenolic, compact | 3"–4" | up to 6,000 lb | Plastex phenolic | Tight under-fixture mounting |

Total the static load and payload, divide by the load-bearing casters, then add 25% margin over the worst-case caster. Low-profile casters give up some ride compliance for height, so do not also shave the capacity margin. Keep the full 25% so the smaller wheel runs well inside its rating on machine bases that load unevenly.
Twin Nylast reaches the full 16,000 lb in the lowest height and resists chemicals and impact. Plastex phenolic carries less but rolls hard and true on smooth floors. Neither protects a finished floor the way polyurethane would, so on delicate floors confirm the surface tolerates a hard wheel before specifying low profile.
Top plate is standard and a low-profile caster is chosen specifically to minimize the stack height from floor to deck. Confirm the plate thickness and bolt pattern carry the rating and that the mounting surface is flat, low-profile casters are less forgiving of an uneven mounting pad than a tall swivel.
OEM machine bases, plant retrofits, and restricted-clearance installs are the typical settings. Nylast tolerates chemicals and impact in plant conditions, phenolic suits clean dry floors. Where overall height drives the whole decision, verify the wheel material still matches the floor and contamination the caster will actually see.
It is a heavy-duty caster built to carry high load in the lowest practical overall height. Hamilton rates the Mini-Mite up to 16,000 lb per caster on twin Nylast or Plastex phenolic wheels. It is chosen for under-machine moves and restricted-clearance installs where a standard caster would sit too tall.
Up to 16,000 lb per caster on the twin Nylast configuration. Plastex phenolic configurations rate lower. Size each caster to the worst-case corner load with 25% margin and do not trade away that margin to gain a little more height.
Twin Nylast and Plastex phenolic. Twin Nylast carries the most in the lowest height and resists chemicals and impact. Plastex phenolic rolls hard and true on smooth floors at lower capacity. Neither protects a finished floor like polyurethane, so confirm the floor tolerates a hard wheel before specifying.
Tight overall-height installs, under-machine moves, and restricted-clearance retrofits are the core applications. It suits OEM machine bases and plant retrofits where deck-to-floor height is fixed by surrounding equipment. The Mini-Mite is specified when height, not capacity, is the constraint.
Yes. Hamilton has manufactured casters in Hamilton, Ohio since 1907. The Mini-Mite line is built domestically, which keeps custom heights and plate patterns available on short lead times for OEM machine builders.
Provide the worst-case load per caster, the maximum allowable overall height, floor condition, and mount plate requirement. We match those to the correct wheel and capacity tier and confirm the Hamilton part. Call 844-439-4335 or send your existing caster spec for a direct cross-reference.
