Frequently asked questions

Is this inox sprocket suitable for the food industry?

Yes, this toothed wheel is made of stainless steel (inox), resistant to water and aggressive cleaning agents, which is a hygiene requirement in the food and chemical industries.

What is the hole for a set screw in the hub for?

The threaded hole (often above the keyway or at 90 degrees) takes a grub screw. It prevents the sprocket from shifting along the shaft during machine vibrations.

When should you choose a sprocket with a hub and when a plate wheel?

Plate wheels are most often used where they are mounted to an existing flange or drum, or when there is very little space on the shaft. Sprockets with a hub are chosen when the wheel must transmit high torque directly from the shaft through a key - the hub gives a longer contact surface.

How to align sprockets correctly during installation?

The driving and the driven sprocket must lie in one line. For alignment use a long steel ruler laid against both sprockets or an alignment laser. Even a small angular deviation quickly destroys the chain.
