Conveyor Belt Speed & Capacity
- Belt speed From drive pulley diameter and RPM
- Bulk capacity Tons per hour from belt width, trough angle, speed and density
- Package throughput Packages per minute from length and gap
Three calculators in one, with the formulas and a short FAQ on surcharge angle, incline and capacity.
Gearbox Ratio, Speed & Torque
- Ratio and speed Output RPM from ratio, or the ratio for a target RPM
- Output torque From motor HP, ratio and efficiency
- Service factor Sizing for speed reducers and gearmotors
For choosing or replacing a speed reducer or gearmotor, with notes on worm versus helical efficiency.
Shaft Torque & Coupling
- Shaft torque lb-in, lb-ft and N·m from HP or kW and RPM
- Coupling size Reuland / Trilex RC size and insert by service factor and shaft size
For sizing jaw couplings on motor and gearbox shafts, with the RC ratings and service factors built in.
Chain Wear / Elongation
- Elongation Percent wear from a measured length of chain
- Limit 3%, or 200 ÷ teeth on large sprockets
For deciding when roller chain is due for replacement, with how to measure it.
Elevator Bucket Capacity
- Throughput Bushels and tons per hour from bucket, spacing and belt speed
- Tapco data CC-HD, CC-LP HD and Super Capacity sizes built in
For centrifugal and continuous-discharge elevators, with a check against Tapco's minimum spacing.
Elevator Bucket Selection Tool
- How it works A step-by-step flowchart
- Result A suggested bucket material
Answer a few questions about your material and application and the flowchart points you to the right bucket material.

FAQ
Are the calculators free?
Yes. Every tool on this page is free to use, with no sign-up. Every calculator shows the formulas it uses, so you can check the working.
How accurate are the results?
They are engineering estimates from standard formulas and the numbers you enter. Use them to size and compare options, then confirm the final selection against the manufacturer's published data, or send us your numbers and we will check them.
Can Jealco supply the parts once I have my numbers?
Yes. Send us the results with your application details and we will quote the belt, gearbox, gearmotor, elevator bucket or other component that fits. As an independent distributor we cross-reference across manufacturers.
