Before you order a rebuild quantity, check two numbers against your existing deck: the 3-3/4" overall height and the 3-1/2" x 2-3/8" bolt spacing. If both match, this is a drop-in swap for 03XN02028S001C with no plate or shim changes. If your drawing calls for more than 450 lb per caster, send it to us before you buy. That is a different caster, not a heavier-duty version of this one.
It is used in air cargo and cargo conveyor equipment, where a short, sealed swivel caster has to carry pallets and containers across a deck. The 3-3/4" overall height keeps deck profiles low, and the double sealed bearings plus the O-ring sealed swivel section keep out the dirt, de-icing residue, and moisture common on ramp and terminal equipment.
450 lb per caster. On a four-caster layout with even load distribution, that is 1,800 lb of total rated capacity. For uneven loads or impact at transfer points, size to the most heavily loaded caster, not the average.
No. This air cargo caster is offered without a brake. Conveyor and roller deck applications hold position with deck stops or locks, not caster brakes.
The two are the same 2-1/4" x 1-3/8" nylon, 450 lb, 3-3/4" height caster on the same 4-3/8" x 3.16" plate. The difference is the toe guard: HQ03XN02028S018 includes the integral metal toe guard, and the no-toe-guard version (cross-reference 03XN02028S004C) does not. Ask us for pricing on that version. Choose the toe guard version where hands, feet, or cargo straps can reach the wheel.
Yes. Part 03XN02028S001C has been superseded by 03XN02028S018, and CasterHQ HQ03XN02028S018 is the direct replacement. If your maintenance records, BOM, or drawings list either number, order HQ03XN02028S018.

This HQ03XN02028S018 2-1/4" Air Cargo Caster w/ Toe Guard, 450 lb is rated to 450 lbs per caster. Size a set by dividing the total load by the number of casters, and for uneven floors assume 3 of 4 casters carry the load. Keep continuous-use loads within about 75-80% of the rating.
This caster runs a Nylon wheel with a 1-3/8" tread width. Nylon resists chemicals and moisture and carries high loads, which suits washdown and wet environments.
This caster uses a top-plate mount with a 4-3/8" x 3.16" plate. Measure your existing mounting holes before ordering; if you are replacing casters, match the bolt pattern - most standard patterns interchange across brands.
This is a Swivel caster. Swivel casters rotate 360 degrees for full maneuverability. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.
The Nylon wheel performs best on smooth, hard industrial floors. For non-marking or clean-environment needs, ask us about matching tread options.
The overall height (floor to top of plate or stem) is 3-3/4". Account for it when checking equipment clearance, dock height, and ergonomic working height.
We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
