FAQ
What does the "B81" designation mean?
"B" identifies the B-section classical V-belt profile (21/32 in wide × 13/32 in thick). "81" is the inside circumference in inches; adding 3 inches gives the 84 in outside circumference.
Is this belt suitable for clutching applications?
Yes. The Flex-Weave wrapped cover makes the Gates B81 suitable for clutching applications as well as standard fixed-centre drives.
Can I use this belt in a matched set?
Yes. Gates B81 belts are part of the V80 matching system, meaning multiple belts can be run in tandem on multi-groove sheave drives without individual belt matching.
