BESTORQ single, wrapped V-belts give premium belt performance. The belts are constructed of highly engineered, high performance components. The components are manufactured using the latest in belt technology available on a global basis. The outer fabric wrap is treated with oil and heat resistant, engineered synthetic rubber compound, specifically compounded for excellent wear resistance, proven through thousands of hours of testing. The helically wound tensile cords are specially engineered, twisted, heat and chemically set, polyester material. Testing has proven that the tensile decay properties of BESTORQ Cord are truly World Class. The body rubber compound is a highly engineered synthetic rubber compound, specially compounded for cool running, flexibility, crack resistance, and excellent bonding to the outer fabric and tensile cords. The belts exceed USA RMA published ratings levels. They are designed to perform at the identical or higher level than all other major USA Manufacturer’s belts of the same type. All 3L, A or 4L, B or 5L, C, D, 3V, 5V and 8V belts are manufactured to meet RMA standards for length and dimensions. All belts of a given size are manufactured to run interchangeably in a matched set. (SPZ, SPA, SPB, SPC, 9J, 15J, and 25J belts are manufactured to fit ISO standard dimension multi-groove pulleys.)
- BESTORQ X3 fabric wrapped V-belts bring in a new generation of wrapped V-belt performance; These belts are constructed of highly engineered, high-performance components that are manufactured using the latest in belt technology available on a global basis
- They are specially designed to be low maintenance and are proven to be extra durable for belt life that will outlast the competition; Reduced maintenance downtime and increased machine uptime means you save time and money
- The helically wound tensile cords are created of a pre-stretched polyester material specially engineered, twisted, then set by both heat and chemical means; Testing has proven that the tensile decay properties of BESTORQ Cord are truly World Class
- X3 v-belts are amazingly uniform and smooth running; With excellent adhesion between components and low stretch tensile cords, they have very low elongation and will not require any rechecks or retensioning if installed at the correct recommended tension
- The BESTORQ A19 or 4L210 v-belt has a 21" outside circumference, 19" inside circumference, .51" width, and a .34" height; See images for cross section schematic
