30 sizing calculators for mechanical, pneumatic and electrical parts, with worked solutions

Engineering Reference now includes 30 sizing calculators, free to use in the browser.

They are grouped by area: mechanical drives (ball screws, LM guides, timing belts, gears, bearings, cross roller rings), motors (stepper and servo sizing for screws, belts and rotary tables), pneumatics and vacuum (cylinders, suction cups, vacuum chambers), electrical and control panels, and machining. Every calculator has a diagram and a "Worked solution" that puts your numbers into each formula, so every step can be checked.

Results are for preliminary selection. Confirm the final choice against the manufacturer's catalogue.
