Double Sided Standard Timing Belts -
DXL, DL, DH Trapezoidal Tooth Profile
(Chloroprene with Fiberglass Reinforcing Cord)
Double sided belts afford power transmission from either side of the belt and are often used
in reversing and serpentine applications.
Double sided timing belts are produced using the same materials as single sided belts, except that the backside is
precision ground from a fiber-reinforced rubber compound. There is no nylon facing on the backside. Power take
off from the backside is limited to 50% of the total Jason/Megadyne design manual rating.
Total belt rating is the same as for single sided belts.
Teeth with nylon cover should always be against the driver pulley.

NOTE: Widths shown are considered standard, but Double Sided Standard Timing Belts can be cut to any width desired.
Double sided timing belts are specified the same way as single sided timing belts except with a "D" prefix -
Example: D240H100
