Mechanical
Bearing Life Calculator
Estimate how long a rolling-element bearing will last under a given load and speed. Use it when selecting bearings for motors, gearboxes, or any rotating machinery to meet a target service life.

Mechanical
Screw Torque Calculator
Calculates the torque needed to clamp a fastener to a target axial force, accounting for thread geometry and friction. Use it when tightening critical bolted joints to avoid under- or over-torquing.
