What is a Roller Deflection Calculator?
This tool estimates theoretical maximum deflection for a simply supported roll under a central point load or full-span uniformly distributed load.
Formula Used
Central point load: delta = P L^3 / (48 E I). Uniform distributed load: delta = 5 W L^3 / (384 E I). Section I = pi/64 x (Do^4 - Di^4).
Assumptions and Limits
The tool uses an ideal simply supported beam model and does not include dynamic loading, temperature, shell/core construction complexity, bearing flexibility or rubber viscoelastic behavior.
FAQs
Is this the final manufacturing camber?
No. It is theoretical beam deflection. Manufacturing camber should be reviewed with actual process and calibration data.
What if my support condition is different?
Select engineering review. Maitrix can develop custom logic for your exact support, load and machine configuration.
