What this tool answers
You need a first-pass manual arbor-press size before buying. Enter required force in tons. The calculator names the smallest class on this site’s ladder — 0.5, 1, or 3 ton — or returns NO_MATCH. It is not a blanking-force FEA, punch-press calculation, or H-frame shop-press selector.
Arbor press vs shop press
Arbor presses are compact lever-operated desktop units for light pressing, riveting, and forming. H-frame hydraulic shop presses (often 6–20 ton) handle heavier pressing. If your job needs more than 3 ton on this ladder, move to a shop-press path instead of forcing an arbor unit.
Class ladder on this site
Classes use published VEVOR US arbor-press ratings checked 2026-09-10: 0.5 ton, 1 ton, and 3 ton. Matching rule: smallest class where rated tons ≥ required force.
When the answer is NO_MATCH
If required force exceeds 3 ton, this site returns NO_MATCH. Typical next steps: confirm units (tons vs pounds), reduce the job, or size an H-frame hydraulic shop press. Do not force a 3 ton arbor press past this screen.
Height, throat, and mounting
Capacity alone is not enough. Check max work height and throat depth against your workpiece. Bolt the press to a sturdy bench. Keep hands clear; wear eye protection.
