Registration Drives: Registration drives are required to register, or position accurately.
Higher belt installation tensions help in increasing belt tensile modulus as well as in increasing
meshing interference, both reduce backlash. Tension values for these applications should be
determined experimentally to confirm that desired performance characteristics have been achieved.
As a beginning point, use values from Table 2 multiplied by 1.5 to 2.0.
Most synchronous belt applications often exhibit their own individual operating characteristics.
The static installation tensions recommended in this section should serve as a general guideline
in determining the level of tension required. The drive system should be thoroughly tested to
confirm that it performs as intended.
