Bearing Engineering Tools
Calculate ratings and operating conditions, then move directly into catalogue-connected bearing selection.
Choose a calculation
Calculators update from the entered values; automatic selection also searches the loaded product database. Use exact manufacturer and application data wherever a catalogue factor is required.
Automatic Bearing Selection
Calculate required C and C0 ratings, then retrieve matching catalogue candidates.
Bearing Load Calculator
Combine radial and axial loads with dynamic and static catalogue factors.
Bearing Life Calculator
Estimate basic rating life in revolutions, hours and calendar years.
Adjusted & Variable-duty Life
Reduce multiple duty blocks and apply reliability and validated life-modification factors.
Shaft and Hole Fit Calculator
Estimate common ISO 286-based limits, clearance and interference.
Internal Clearance Calculator
Estimate mounted operating clearance after fit and thermal reductions.
Lubrication & Relubrication
Estimate operating viscosity, κ and a condition-adjusted grease interval.
Friction, Power & Heat
Convert friction torque into rotational power loss, heat and daily energy.
Preload & Stiffness
Check axial displacement, reactions and unload threshold for an opposed pair.
Bearing Fault Frequency Calculator
Calculate BPFI, BPFO, ball-spin and cage frequencies for vibration analysis.
Thermal Expansion Calculator
Calculate growth, contraction, final dimension and thermal strain.
Look up the inputs before calculating
Calculation aids, not selection approval
- 01Use exact product data
Ratings, factors, geometry and tolerances can differ by bearing type, suffix and manufacturer.
- 02Keep units consistent
Each calculator labels the required unit and converts only the values explicitly shown.
- 03Verify critical decisions
Confirm final values against the current standard, manufacturer catalogue and application requirements.
