Measure your existing equipment plate bolt-hole pattern with calipers. The 6″ x 7-1/2″ plate uses a 4-1/2″ x 6″ bolt pattern. Replacement casters must match BOTH the overall plate dimensions AND the bolt-hole spacing — even 1/16″ off prevents bolt-for-bolt install. Photograph the existing mount and email info@casterhq.com if unsure.
Total cart load divided by 4 casters, plus 30% safety margin (50% for outdoor or shock applications). The 6″ x 7-1/2″ plate supports up to 10,000 lb per caster — that’s 40,000 lb total cart capacity at 4 casters. Match to your actual load, don’t exceed.
Available wheel range: 10″ - 14″. Smooth concrete: smaller wheels work. Floor seams, thresholds, debris: 6″+ minimum. Outdoor or rough surfaces: 8″+ required. Larger wheels reduce push force by ~30% per 2″ diameter increase.
Standard options for 6 x 7-1/2 plate: poly-on-iron (highest capacity, non-marking), cast iron (max capacity, marks floors), phenolic (heat-resistant), polyurethane (non-marking, quiet), pneumatic (rough terrain, shock absorption). Email info@casterhq.com with environment for material recommendation.
A top-plate mount industrial caster sized for the 6″ x 7-1/2″ bolt pattern. Capacity up to 10,000 lb per caster on 10″ - 14″ wheels. The plate dimensions and bolt pattern (4-1/2″ x 6″) determine compatibility with existing equipment mounts.
Up to 10,000 lb per caster at static rating. For a 4-caster cart: 40,000 lb total capacity. Always size 30% above your peak load for safety margin (50% for shock-load applications).
The 6″ x 7-1/2″ plate supports 10″ - 14″ wheels in standard configurations. Larger wheels require longer hub bores but the top-plate dimensions stay constant. Verify wheel-to-floor clearance after install.
Measure your existing mount with calipers: overall plate dimensions (6″ x 7-1/2″) AND bolt-hole spacing (4-1/2″ x 6″). Both must match for bolt-for-bolt replacement. Photograph the existing caster mount and email info@casterhq.com for cross-reference verification.
Hamilton (heaviest capacity, mil-spec), Albion (USA-made, widest selection), Faultless (economy industrial), Caster Concepts (custom-engineered, fastest lead time for non-stock), and Service Caster (light-to-medium duty). All cross-reference supported.
Standard 6″ x 7-1/2″ casters: zinc-plated or zinc-yellow chromate steel for indoor industrial. Stainless (304 or 316) for wet, washdown, food, pharma, chemical environments. Stainless costs 2-3x more and capacity is 70-80% of equivalent steel. Specify by environment.
Industrial plate casters ship without bolts — bolt length depends on frame thickness. Standard bolt sizes for 6″ x 7-1/2″ plate: 5/16″-18 to 1/2″-13 grade 5 zinc-plated. Use 4 bolts + lock washers + nuts per caster.
Stock 6″ x 7-1/2″ casters ship same day from Mansfield, TX before 3pm CT. Freight-class sizes (10,000 lb capacity and above) are quoted at order. Engineer cross-reference: next-business-day response from info@casterhq.com.
