DH Inch Sizes Double-Sided Timing Belts
DH Inch Sizes timing belts with trapezoidal profile have been designed for drives with reversing direction of rotation.
The standard design allows economical solutions for double-sided synchronous power transmission in the lower and middle power range.
Belts Construction

- Polyamide fabric
- Synthetic rubber teeth
- Glass cord tension member
- Synthetic rubber backing
Belts Fields of Use
The double-sided timing belts with trapezoidal profile in inches are suitable for synchronous drives with same-sense and counterrotating motion. They allow compact space and weight-saving drives with an efficiency of up to 98 %.
Belts Characteristics
- High transmission power and long life
- Conditionally resistant to oil
- Suitable for tropical climates
- Electrical conductivity according to ISO 9563 for high performance variants
- Temperature range depending on application, from -20 °C to +100 °C
