Mechanical
Rolling Bearing Life Calculator
Estimate how long a rolling bearing will last under real operating conditions. Enter load ratings, speed, and reliability factor to get predicted bearing life in hours.
Fill in the required fields to see your result.
Mechanical
Screw Thread Stress Calculator
Calculates the shear stress on screw threads given applied force, thread geometry, and engagement length. Use it when verifying that a threaded joint won't strip under tensile or torsional loading.
