Plate Mount Casters

Fast way to spec plate casters: match the existing plate footprint, then select wheel material for floor type, load, and duty cycle. Below are the most common plate formats used across carts, fixtures, equipment bases, and OEM builds.

Most common plate sizes

Institutional / light-duty footprint. Common where compact mounting is required and the wheel width is typically ~1-1/4" (model dependent).
Mid-size footprint used across carts and fixtures that need more mounting support than institutional plates without stepping into heavy-duty top plates.
The common “universal” industrial plate. Frequently paired with ~2" wide wheels on tool carts, racks, dollies, and general MRO builds.
Heavy-duty footprint for higher loads and larger wheel assemblies (often ~3" tread widths, model dependent). Used on industrial equipment, machinery carts, and high-impact service.

These footprints cover the majority of plate-caster replacements and new builds. Always verify plate dimensions and hole spacing against your equipment before ordering.

How to choose the right plate size (quick method)
  • Match the plate footprint first (overall plate size + bolt hole pattern).
  • Confirm clearance: swivel radius, overall height, and brake envelope if applicable.
  • Select wheel material based on floor condition, noise requirements, and cleaning chemicals.
  • Capacity check: use per-caster dynamic rating with a safety factor for real duty cycle.
Why plate size matters for OEM and MRO
  • Improves load distribution into the frame and reduces fastener pull-through risk.
  • Controls swivel stability under side-load and frequent direction changes.
  • Standardizes replacement across fleets (fewer SKUs, faster maintenance).
