Unique flexible diameter rolling fixture developed by Onvio to apply pressure on a variety of pulley sizes.

What Competitors Often Do

Don’t suffer a breakdown due to a failure of the weakest link:

Low quality timing pulleys use multi-location staking to install the flange – this type of flange installation can fail due to simple heat and/or vibration.

Customers have actually had flanges come loose from the pulleys during shipment.

Those customers now rely on Onvio timing pulleys and their problem was solved!


360 degree “Rolled” pulley flange installation

A very simple feature that sets Onvio timing pulleys apart from the rest!

Timing pulley flanges are intended to provide a slight “guide” effect on the timing belt. However, many applications can overload the standard flange rating due to directional “wandering” of the belt, misalignment, or a number of other factors.

Flange installation processes that do not provide a true 360 degree rolled contact point are likely to be overloaded and suffer from premature failure. Due to our long history in the design and proper application of timing belts and pulleys, Onvio has developed a unique — proprietary flange rolling — installation process that will ensure that the timing pulley flanges do their job – even when overloaded.

Onvio also offers timing pulleys that can be specified with “screw on”, or “bolt on” flanges. This may be the result of pulley O.D., high belt forces applied during operation, or simply customers requiring “removable flange” access for belt replacement/maintenance.
