A synchronous high-torque range of timing pulleys and belts is one of the latest product lines to be added to the power transmission and gears selection offered by Ondrives.

These pulleys and belts start at 5mm pitch as standard and increase to 10mm.

Belt widths start at 10mm and increase to 50mm.

The pulleys are aluminium with zinc-plated steel flanges with other materials available on request and are centre drilled or pilot bored.

The belts are specially formulated from a steel reinforced polyurethane and have a high-power metric pitch AT profile with trapezoidal tooth form.

There are a number of options available on certain belt lengths such as anti-static, coloured, machined, ground and punched belts.

Other optional extras also include backings, brush belts, increased power versions, Aramid (Kevlar) tension members and special polyurethanes.

A Generation III version is also available for the AT5 and AT10 pitch belts; these are manufactured from a very high-power metric pitch AT profile with trapezoidal tooth form, composite PU carcass and bifilar ‘S’ and ‘Z’ twist spirally wound tension members.

Ondrives said that these timing belts offer characteristics to suit almost any application where high performance is necessary.

The 5mm Gen III version is available from 10mm, 16mm or 25mm widths and the 10mm pitch versions are offered in 25mm, 32mm and 50mm widths.

These are available off the shelf.

Open-length belts are also offered as an option in this high-torque range.

These are single-sided joined belts in steel reinforced polyurethane.

The usual widths are available for both pitches with 75mm, 100mm and 150mm on request.

Optional extras are available for the open-length belts, including E-tension members, special polyurethanes, nylon facing (tooth and back), transport backing (up to 100mm wide), anti-static, coloured, machined, ground and punched belts and mechanical joints.

Unplated aluminium clamping plates are also available for use with the AT type belts where needed.
