Variable Speed Belts

COMPARE . . . YOU’LL SEE THE DIFFERENCE.

Q–Power® belts keep expensive farm equipment running.  The Q–Power® Belt program offers the farmer heavy duty, long lasting belts from local sources of supply.

All of our agricultural belts are manufactured to American Society of Agricultural and Biological Engineers (ASABE) specification S211.6 specifically for agricultural applications.  Our Q–Power® Belts have been in the field in Europe, North America, South America, and Africa for many years.  They have proven to be able to perform in any harvest condition. Q–Power® Belts have been extremely well received by our network of distributors and the ultimate consumer.

All you have to do is look at our Q–Power® Variable Speed Belt. You’ll see the difference in design, materials, and construction.

Quality Power Products, Inc. has used the highest quality materials and the most advanced manufacturing processes to build our Q–Power® Belts. Q–Power® Variable Speed Belts are often the largest and most important belts used on agricultural machinery.  These belts can propel a machine weighing several tons through a field and match the speed of the machine to precisely the optimum speed required for harvest conditions.  As cylinder or rotor drive belts they again match the speed of the equipment to that required to effectively thresh and separate grain.

Agricultural variable speed belts differ from Industrial “speed changer” belts in that they transmit much higher loads over a narrower speed range. Therefore, agricultural variable speed belts require higher tensile strength and are thicker with more reinforcement in the tensile support than industrial belts.

Features and Benefits of Q–Power® Variable Speed Belts:

  • Q–Power® Variable Speed Belts are produced to ASABE Standard S211.6 - Q–Power® Belts provide perfect fit on combine drives.
  • Q–Power® Variable Speed Belts have a highly engineered rubber compound reinforced with KEVLAR® fiber which gives our Q–Power® belts superior transverse rigidity and heat resistance.  These fibers add mass to prevent the belt from collapsing under the heaviest loads and excellent stability on hot summer days.  Helps eliminate spin-burn damage and allows precise harvest speed.
  • Q–Power® Variable Speed Belts have heavy gauge KEVLAR® tensile members which are five times stronger than steel by weight for high break strength.  These tensile members will keep your machine in the field. Q–Power® Belts will keep you running.
  • Q–Power® Heavy Duty Rotor Drive Belts have cogs on both the inside and outside diameter. These rotor drive belts are the only one piece rotor drive belts with cogs on the outside diameter in the industry.  The cogs are molded to precise engineering tolerances to improve flexibility and maintain cord support.  Cog geometry provides a large area for air circulation to keep the belt cool and prevent damaging heat buildup in the cushion section.

Typical Applications:

Combine/Harvester - Rotor Drive Belt
Main Drive Belt
Header Reel Drive Belt

Every element of the Q–Power® Variable Speed Belt is designed to deliver premium, long–life performance in demanding agricultural machines.  They are engineered to withstand the abuse of repeated sudden shock loads, tolerate high ambient temperatures, and resist the damaging effects of oil and dust.
