Calculation tools for mechanical engineering

Free calculators for the questions that come up most often in the technical office and on the shop floor. They give a first answer in a few seconds; when the real case needs more, there's our consulting.

Free and no registration. The results are preliminary estimates: if you need help with a project, request a consultation or call +39 333 829 7733.

ISO 286 tolerances and fits

Free ISO 286 tolerance calculator: deviations, limit diameters, clearance and interference for fits up to 500 mm.

Sheet metal flat pattern and K-factor

Calculate the flat length of a bent sheet with the K-factor: bend deduction, bend allowance and K-factor estimate according to DIN 6935.

Hydraulic system pressure

Pressure calculator for hydraulic systems: force and speed of a cylinder, required pressure and pressure drops.

Static and fatigue check of a shaft

Static and fatigue verification of a shaft with Goodman, Marin and von Mises, also from a STEP file: diameters, fillets and Kt from the model.

Power, torque and motor selection

Calculate the power, torque and speed of a drive and choose the motor: IEC frame size, number of poles and reduction ratio.

Pulleys and gears

Calculator for belt drives and gears: ratio, speed, belt length, wrap angle and centre distance.

Lighting calculation

Lighting calculation with the lumen method: number of LED luminaires, average illuminance in lux and installed power.

Unit and physical quantity converter

Free converter of units and physical quantities: mechanics, fluids, heat, electricity, magnetism and radiation, with over 350 units.

Bearing selection and verification

Select and verify bearings with the ISO 281 method used by SKF: L10h and Lnm life with aISO, viscosity and static safety.

Technical consulting

Calculation is the first step

Sizing, structural and fatigue verification, compliance and documentation: if you need help with a real project, contact us for a consultation.
