Professional-use disclosure
What casterscalculator.org is for, what its results can and cannot support, and the assumptions each family of tools rests on. The equipment, the floor, the manufacturer's published ratings, and your actual duty cycle always win over a web page.
Screening outputs, not approvals
Every calculator result, lookup value, guide example, and generated report on this site is a first-pass screening figure. None of them is engineering or design work, a load-rating certification, a safety approval, a supplier quote, an inspection, or a guarantee of service life or cost. A result is a starting point for a decision, and it is never a substitute for the manufacturer's datasheet, the actual equipment, the actual floor, and the conditions the casters will work in.
Published ratings and standards come first
Where the site refers to a capacity, a mounting dimension, or an industry practice, the manufacturer's published data for the exact part and the standard adopted in your industry govern. If a calculator result and a published rating disagree, the published rating wins, without exception. A number printed in a caster catalog may be a static rating, a dynamic rating, or a test-condition figure; confirm which one it is before relying on it. Load, mounting, towing, and other safety-related work should be checked by a competent person before equipment is put into service.
What each family of tools assumes
- Load and capacity figures assume a static, evenly shared load unless the tool says otherwise. Real equipment sees impact from dropped or set-down loads, off-center centers of gravity, towing forces, and floor transitions. A per-wheel figure that meets a catalog rating is a starting point, not proof that the caster will survive the duty.
- Mounting and fit results are computed from the measurements you enter. Plate and bolt patterns, stem sizes, and overall heights vary between manufacturers and change over product revisions. Measure the part and confirm the drawing before ordering; a match within a tolerance is not a promise that the replacement is interchangeable.
- Push, pull and ergonomics figures depend on the rolling-resistance value you supply and on ideal conditions. Actual effort varies with floor roughness, debris, temperature, wheel wear, bearing condition, and how the load is distributed. Use the result to compare options or to screen for ergonomic concern, not as a measured floor test.
- Floor and environment point-load estimates approximate the contact area of a loaded wheel. Slab capacity, floor protection, and temperature or washdown suitability require the building's structural information and the manufacturer's material data; the tools organize the comparison but cannot certify the floor.
- Wear and failure tools map symptoms to likely causes and typical causes to actions. They cannot confirm a failure mode without inspecting the actual caster, and any replacement interval they suggest is an estimate that depends on the load ratio, travel distance, floor, and speed you enter.
- Cost figures are arithmetic on your own prices, labor rates, and replacement frequencies. They are not quotes, and they exclude costs you have not entered, such as freight, downtime, floor repair, or the labor of inspecting the fleet.
Prices, ratings, and material data need verifying
- Catalog prices and labor rates: confirm current quotes, volume price breaks, and local labor rates before trusting any payback or budget figure.
- Capacity ratings: confirm whether a rating is static or dynamic, the speed and test conditions behind it, and any temperature or duty de-rating the manufacturer publishes.
- Wheel and bearing data: confirm hardness, temperature limits, chemical resistance, and bearing type from the datasheet or the label, not from a summary.
- Outside data: where a page quotes a benchmark, a coefficient, or a price, the page names the source and, where it applies, the data year. Those figures are context for a decision, never a substitute for your own number.
No paid placement, no affiliate steering
No caster manufacturer, distributor, integrator, or service provider pays for a recommendation, a default value, a ranking, or a mention in a guide. The site carries no affiliate links and receives no commission on equipment or services. Defaults are editorial choices about what a reasonable starting point looks like, and they are labelled as defaults so you can replace them. If a commercial relationship is ever introduced on a specific page, it will be stated on that page, and the tool itself will still let you override every value.
How errors are handled
If a page has an unclear definition, a calculation that does not match its stated formula, a stale rate, or a source you cannot trace, the correction takes priority over adding anything new. Send the URL and the specific problem through Contact. Verified errors are corrected, and the pages that depend on a corrected table are re-checked against their test cases before the fix is published.
Your own responsibility
You decide what to build or buy. Casters Calculator supplies arithmetic and context; it does not know your equipment, your floor, your duty cycle, your budget, or your tolerance for risk. Treat every result as a question to be verified rather than an answer to be relied on, and on anything safety-related or structural, obtain the judgement of a qualified professional before you commit money or put equipment into service.
