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.
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.
