Description Technical Specs
 
Premium quality A138 v-belts are becoming less common in today's "budget-friendly" world, but our classic A138 v-belts, also known as 4L1400 v-belts are made with some of the highest quality material options and provide a long-term performance operation when compared to some of the other belts out there. These high-strength A138 belts are designed and manufactured in a way that allows perfect tandem in multiple A138 belt drive applications. More specifically, this A138 v-belt is made to ARPM standards, is 140" overall outside length, and has natural oil and heat resistance in harsh environments. Because of the high-performance versus relatively low upfront cost, v-belts are becoming more and more common in new and existing applications.
A138 V-Belt Construction:
  • Cover - High-quality cotton/ polyester blend
  • Compound - Natural rubber/ styrene-butadiene rubber (SBR)
  • Cord - High-strength polyester
Note: We also have Cogged V-Belts which include longer operational life, cooler running, and around a 2% higher efficiency raring than a standard v-belt.
