FAQ

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.
