Air Cooled Heat Exchanger (ACHE) Synchronous Timing Belt 3360-14M-42F

Timken ACHE (Air-Cooled Heat Exchanger) synchronous belts are manufactured using a special construction.

Because the drive has a vertical shaft, the belt is built with "Z" twist cords only.

This gives the belt an upward direction of lateral movement which reduces excessive wear on the bottom side of the belt.

The cord in a synchronous belt is made up of a number of small fiber strands twisted together.

These strands can be twisted either clockwise or counterclockwise.

The two twist directions are referred to as "S" twist and "Z" twist.

To reduce lateral movement, most synchronous belts are constructed by alternately spiraling "S" and "Z" type cords.

Timken ACHE belts use only "Z" twist cords to predetermine the lateral movement of the belt.
