TENSION BELT TESTER : FENNER OPTIBELT GATES
belts are Precision Built to ensure inherent
length stability and matching during storage and on the drive.
Over many years, the principle of "one-shot" tensioning has
been verified by successful drives the world over.
Install the belts to be a snug fit around the
Spin the pulleys 3-4 revolutions to bed belts into
the pulley grooves.
(Note: if done manually, beware of finger entrap-
ment between belts and pulleys)
Tension the belts to the 1.25x setting forces
from the table.
Run the drive under load for 15-20 minutes.
Stop the drive, check tension & reset to the basic
value (standard V and wedge belts) if necessary.
CRE PLUS & Quattro PLUS belts should be reset
to the 1.25x value.
With a drive that is properly designed for the application
there should be no need for further attention during the
life of the belts.
For short centre distance drives where the deflection of the
belt is too small to measure accurately it is recommended
that both deflection and setting force be doubled.
Method of belt tensioning using Fenner Belt
Calculate the deflection in mm on a basis of 16mm
per metre of centre distance. Centre distance (metres)
x 16 = deflection (mm).
Set the lower marker ring at the deflection di
