Pulley Description

EAGLE M-20S-MPB (8M-25) is a basic type of pulleys for polyurethane belts with helical offset teeth in EAGLE 8M profile, or for rubber CONTI SILENTSYNC belts. It is made of aluminium alloy with a pilot bore.

They enable to design unique drives for transmission of the highest power and speed with reduced noise. The belts used are self-guiding and do not need to be guided by flanges or in another way.

The pulleys are supplied as a semi-finished product and the internal hole must be modified before mounting the pulleys on the shafts.

Pulley Fields of Use

EAGLE M and L timing pulleys are especially designed for linear applications where are used EAGLE 8M linear polyurethane open-ended timing belts. They are also used in applications with endless or welded with helical offset toth for transport or drive applications.

They are typically used in cases where quiet operation and self-guiding function of the timing belt without external guidance is required – in rack stackers, portals, carriages, machine tools, glass machines, conveyors, etc.
