NOTCHED V-BELT Brand new, BESTORQ notched, classic profile V-belt. Highly oil and heat resistant. Notches give belt superior flexibility around pulleys and longer working life compared to standard V-belts. BESTORQ belts exceed RMA published ratings.
What is the load rating of this belt? Lb. of pull force dynamic at 65 RPM? Do you offer toothed sprockets (sheaves) for these belts? Looking for 4" diameter and 5.5 in. diameter Two each. 7/8 Dia. hub for 4 in. and 3/4 in dia. hub for 5.5 in.
A: The manufacturer does not provide any load rating for their belts. The notches are only to facilitate operation on smaller diameter pulleys without sacrificing torque transmission and are not meant to be utilized as a cog-type belt. We have no cogs for use with cog-type belts. We do carry v-belt pulleys in the sizes you detail-1-BK40-D (3.95") and 1-BK57-C (5.45").
