PRIME MOVER BELTS
Unicord Construction
Thermoid Prime Mover is a premium-rated, heavy duty
industrial V-belt. It is available in A, 8, C, D & E cross­
sections. This one versatile belt can power virtually every
drive in your plant. Prime Mover belts are oil and heat
resistant and static conducting:
8-section belts 120" through 158" and C-section belts 120"
through 300" are branded Unicord~ They are produced to
much tighter Sure-Set tolerances, ensuring excellent match­
ability. The center distances variations have been reduced
on Unicord belts, producing smoother-running belts.
Multicord construction is standard for D and E sections;
special order for C section.
A and 8 belts up to 100" are dual branded with the
corresponding FHP number. For example, 860 (5L630).
A section belts may be used in place of 4L light duty FHP
belts, and 8 section belts may be used in place of 5L light
duty FHP belts.
Mutticord Construction
Now dual branded with FHP number.
Sure-Set®
Belts marked Sure-Se are produced to Sure-Set tolerances.
Sure-Set indicates that all belts of a given size and style are
matched. Contact Elgin for special matching requirements.
