Product Details

The Gates A31 Hi-Power II is a classical A-section wrapped V-belt engineered for reliable power transmission across a wide range of industrial, agricultural, and accessory drive applications. With an inside circumference of 31 inches and an outside circumference of 33 inches, this belt delivers consistent performance in both single-belt and multi-belt drive configurations.

Key Features:

  • Flex-Weave™ Cover: Patented single-layer fabric construction provides extended protection to the belt core from oil, dirt, heat, and other contaminants for longer service life
  • Flex-Bonded Cords: Polyester tensile cords are strongly bonded to the belt body, ensuring uniform load distribution and resistance to bending stress, fatigue, and shock loads without cord deterioration
  • Gates Curves Design: Optimized belt cross-section provides proper cord support and full contact with the sheave groove for uniform loading, uniform wear, and increased belt life
  • Arched Top Construction: Prevents "dishing" and distortion of the tensile section, keeping cords properly aligned so each carries its full share of the load
  • Gates V80™ Matching System: Tight manufacturing tolerances mean every A31 belt meets V80 system matching standards — use individually or in matched multi-belt sets without match numbers
  • Oil & Heat Resistant: Meets ARPM/RMA IP-3-2 oil and heat resistant standards; EPDM compound resists weathering, ozone, sunlight, and aging
  • Static Conductive: Meets ARPM/RMA IP-3-3 static conductivity requirements (ISO 1813); suitable for ATEX-directive environments
  • Fire Resistant: Engineered belt material resists self-ignition, even under severe slippage conditions

Specifications:

  • Belt Section: A (Classical)
  • Top Width: 1/2 in (0.50 in)
  • Nominal Thickness: 5/16 in (0.31 in)
  • Inside Circumference: 31 in
  • Outside Circumference: 33 in
  • Material: EPDM rubber compound with polyester cord reinforcement
  • Temperature Range: -22°F to +140°F (-30°C to +60°C)
  • Gates Part Number: 9002-2031

The Gates Hi-Power II A31 V-belt is suited for HVAC systems, air compressors, conveyor systems, centrifugal pumps, agricultural equipment, and general-purpose industrial power transmission drives. REACH and RoHS 2 compliant.

Exactly what I was looking for. Arrived quick and in good condition. Parts function as required and I am happy with the product and the service.

.

I ordered several days b4 Xmas and I wasn't expecting my tires until after Xmas but to my surprise they were there within like 3-4 days. I was very happy because I had to put air in my tires everyday from leaking and they were splitting at the threads. Great service!!

haven't used it yet

Simple order process

Fast shipping and product described as so. Will order from the in the future.

Just as ordered

Easy, Cheap prices

Drop down menus difficult to find what was needed at times.

I went through the Amazon payment option and it was a hassle.

GOOD SERVICE , FAST SHIPPING , GREAT PRICE !!!!!

My first order did not include all parts. I'm ordering a different part number now. The seller is giving me a discount due to this inconvenience. We will see how it goes.

Good pricing is what brought me here. But I also appreciated the good detail specs about the part I purchased.

Great pricing and fast checkout with amazon pay! Thanks!

Smooth transaction! Best price on the floor liner I was looking for, shipped promptly with tracking info provided, exactly as advertised. THANKS!!

Quick and easy thanks

I only gave them a 3 star raring on their shipping because I went on their site on Tuesday and the order said it had not been shipped. On Wednesday I received my shipment. The left hand needs to figure out what the right hand is doing. Other than that, GREAT
