The existing belts were not lasting 1 month before requiring replacement even with the belts being retensioned. The belts were eroding within the harsh environment and debris present leading to excessive slippage and pulley groove wear. A simple indication is how low the belts were riding in the pulley grooves.

Solution Description
Belts = 10 x SPC5000P Predator® V-belts
DriveR Pulley = 10/SPC475
DriveN Pulley = 10/SPC1000

Benefits of Gates Product

The Predator® belts have successfully achieved 18 months service life with no maintenance required and are still showing no signs of abnormal wear.
With only 10 Predator® belts required, 4 less than previously installed, they still achieved 10 times more life. The new drive also allows standard off-the shelf pulleys, resulting in large cost savings.
