CasterHQ low profile casters are engineered for clearance-sensitive equipment requiring reduced overall mounting height without sacrificing structural load capacity. With overall heights ranging from 2-3/16" to 4-5/32", these casters are commonly specified for vending machines, server racks, refrigeration systems, medical equipment, and OEM machinery builds.
Our low profile series is designed for commercial and industrial environments where footprint, stability, and durability must align with space constraints.
| Series | Wheel Diameter | Capacity (Per Caster) | Overall Height Range | Mount Options | Brake Options |
|---|---|---|---|---|---|
| 01 Series | 2" | Up to 300 lbs | 2-3/16" – 2-1/2" | Plate / Stem | Side Lock |
| 03 Series | 3" | Up to 500 lbs | ~3-1/2" | Plate / Stem | Side Lock |
| 05 Series | 3" | Up to 800 lbs | Up to 4-5/32" | Plate | Total Lock Available |
Mounting heights range from 2-3/16" up to 4-5/32" depending on wheel size and series.
Load capacities range from 180 lbs to 800 lbs per caster depending on series.
Select models include total locking mechanisms that secure both swivel and wheel rotation.
Common in vending, refrigeration, medical, data centers, retail fixtures, and OEM machinery builds.
Low profile casters reduce overall mounting height while maintaining comparable structural strength.
Yes. Polyurethane and rubber wheel options are suitable for sealed concrete and industrial surfaces.
Yes. Select series offer threaded stem and grip ring options for equipment requiring stem installation.
Divide total equipment weight by the number of casters used, then apply a safety factor for uneven surfaces.
These calculators apply to any caster application—even if you’re browsing a different category. Use them to estimate load rating per caster, select wheel material, and estimate push/pull force. Expand any tool for full analysis + a share-ready spec line.
