How to find the right Plate Casters AI guide

What the AI looks for in Plate Casters

Plate size and bolt pattern: Measure the bolt hole centers on your existing caster or mounting surface and buy that exact pattern. A common US heavy-duty pattern is a 4 x 4-1/2 in plate with 2-5/8 x 3-5/8 in hole spacing. Plate sizes vary by duty class, and a mismatched pattern means redrilling.
Overall mounting height: Match the overall height on every caster of one cart, and check that the new height clears handles, doorways and docks. Mixed heights make a cart rock. A height change can also make the cart tip or unusable at existing workstations.
Swivel construction: Choose a kingpinless or heavy-duty raceway swivel for shock loads, dock plates or towing; a standard kingpin swivel suits ordinary pushed carts. Kingpins loosen and fail under repeated impact.
Swivel lead: Use more swivel offset (lead) for easier turning at higher speeds; use less for heavy, slow loads. Offset sets how readily the wheel aligns to the push direction and how much it shimmies.
Rigid plus swivel pairing: Buy rigid and swivel versions from the same series so the heights and plates match. Mixing series usually means different heights and bolt patterns.

Colson: Wide range of industrial plate casters in many series and plate sizes.
Hamilton: Heavy-duty and kingpinless plate casters for high loads.
Albion: Broad plate caster catalog from light to heavy duty.
RWM: Industrial plate casters, including heavy-duty and kingpinless types.
Blickle: Metric plate patterns, useful when replacing casters on European equipment.

Buying by wheel size alone without checking the plate and bolt pattern.
Stamped light-duty plates under carts that get towed or bumped over dock plates.
Metric-pattern plates as drop-in replacements for inch-pattern casters, or the reverse.

Many plates have slotted holes that cover two patterns. Otherwise, use an adapter plate or redrill, keeping enough edge distance in the frame.
