AT Pilot Bore Timing Pulleys for Polyurethane Belts
AT timing pulleys are the basic type of pulleys for polyurethane belts with a trapezoidal AT profile. They are made from aluminium alloy as unbored or with a pre-drilled hole.
The pulleys are supplied as a semi-finished product and the bore must be modified before mounting the pulleys on the shafts.
Pulleys Fields of Use
AT timing pulleys are designed for all types of AT polyurethane belts.
They are typically used in machine tools, packaging machines, printers, single-purpose machines, in the food, paper and glass industry and many other industries.
Pulleys Material
Aluminum alloy.
Other materials to order.
The design for Taper Lock housings must be custom made, aluminum alloy must not be used, but steel must be used.

Notice
The catalog data sheets serve only as a recommendation for the types and dimensions of aluminum alloy pulleys for standard widths and numbers of teeth. All AT20 pulleys are custom made only.
Timing pulleys in the AT versions can also be made to order in the "SE" reduced backlash version and the "0 backlash" / "0-Lücke" version with zero backlash.
