Application 
Plastic Extruder
150kW @ 990rpm

A high capacity belt drive was required for a high power plastic extruder. The challenge was to transmit this power, but only a very narrow space was available and the shaft lengths were quite short.

New Drive Challenge
This application would require 30 standard SPB V-belts (586mm wide) with the same diameter pulleys as the final Poly Chain® GT® Carbon™ solution (90mm wide).

Even a high performing HTD timing belt would need to be 170mm wide with sprockets twice the diameter to transmit this load.

An ultra-high power density belt drive was needed.


Solution Description
Belt = 14MGT-2660-90 Poly Chain® GT® Carbon™
DriveR Sprocket = 38 Tooth
DriveN Sprocket = 90 Tooth

Benefits of Gates Product

The Poly Chain® GT® Carbon™ belt can transmit the 150kW in only 90mm wide, unlike any other product on the market.
