V-Belts
V-belts are oil, heat and static resistant type and over-
sized for continuous duty.
The condition and the amount of belt deflection should
be checked prior to start-up. Do not over-tension as
bearing damage may occur. Recommended belt tension
is 1/64" multiplied by the center distance of sheaves (in
inches). (See Figure 11.)
Extreme care must be exercised when adjusting V-belts
as not to mis-align sheaves. Any misalignment will cause
a reduction in belt life and will increase the likelihood of
noise & vibration.
