Kevlar (Aramid) B-Section V-Belt — 5/8" Width (BK / 5LK)
Heavy-duty Kevlar (aramid) B-section V-belts with a 5/8" (0.63") top width and B/5L profile. The standard polyester tensile cords are replaced with high-strength aramid (Kevlar) cord, delivering greater tensile strength, minimal stretch under load, and long service life in demanding drives.
The dry-wrapped cover is engineered to withstand reverse bending, twisting, severe clutching action, shock loads, and backside-idler applications — making these belts an excellent upgrade or replacement for standard B / 5L belts.
