Same cross-section, same sheave &mdash; direct substitutes when lengths match.</p><p>Stock A38&ndash;A55 range to cover the majority of residential and light commercial HVAC service calls.</p><p><strong>In stock and ready to ship.</strong> Order today for immediate shipment on all stocked sizes.</p>

<h2>AX V-Belts &mdash; Cogged A Section HVAC Drive Belts</h2><p>The <strong>AX cogged V-belt</strong> is the drop-in upgrade to the standard A belt &mdash; same 1/2&quot; &times; 5/16&quot; cross-section, same sheave, measurably better performance. <strong>Cogged raw-edge &bull; 1/4&ndash;10 HP &bull; Min. sheave 2.2&quot;</strong> &bull; IC = part number (OC = IC + 2&quot;).</p><p>Up to <strong>30% more power capacity</strong>. Runs cooler. Lasts longer. Operates on sheaves as small as 2.2&quot;. Many chief engineers and facility managers standardize on AX for all A-section drives to reduce PM frequency and eliminate callback visits.</p><p><strong>In stock and ready to ship.</strong> Order today for immediate shipment on all stocked sizes.</p>

<h2>B / 5L V-Belts &mdash; Commercial HVAC Air Handler &amp; Rooftop Unit Belts</h2><p>The <strong>B/5L V-belt</strong> is the single most common drive belt in commercial HVAC &mdash; rooftop units (RTUs), air handling units (AHUs), packaged systems, and condenser fan drives. <strong>21/32&quot; top width &bull; 13/32&quot; depth &bull; 1&ndash;25 HP &bull; Min. sheave 5.4&quot;</strong> &bull; B-section: IC = part number (OC = IC + 3&quot;) | 5L: OC = part number &divide; 10. Same cross-section &mdash; direct substitutes when lengths match.</p><p>Stock B45&ndash;B75 range to cover the majority of commercial RTU and AHU service calls. A failed blower belt takes down an entire zone &mdash; keep these on hand.</p><p><strong>In stock and ready to ship.</strong> Largest selection of B and 5L sizes available for immediate shipment.</p>

<h2>BX V-Belts &mdash; Cogged B Section Commercial HVAC Drive Belts</h2><p>The <strong>BX cogged V-belt</strong> is the performance upgrade to the standard B-section &mdash; the most common belt in commercial HVAC. Drop-in replacement, same sheave, no modifications. <strong>21/32&quot; top width &bull; 13/32&quot; depth &bull; Cogged raw-edge &bull; 1&ndash;25 HP &bull; Min. sheave 4.0&quot;</strong> &bull; IC = part number (OC = IC + 3&quot;).</p><p>Up to <strong>30% more power capacity</strong>. Runs cooler. Longer service life. Many property management companies and chief engineers standardize BX across AHU and RTU inventories &mdash; lower total maintenance cost, fewer emergency call-outs.</p><p><strong>In stock and ready to ship.</strong> Order today for immediate shipment on all stocked sizes.</p>

<h2>C / CX V-Belts &mdash; Heavy-Duty Commercial HVAC &amp; Industrial Drive Belts</h2><p><strong>C and CX V-belts</strong> power the largest drives in commercial HVAC &mdash; large-capacity AHUs, cooling tower fan drives, industrial exhaust fans, and heavy-duty blower systems. <strong>7/8&quot; top width &bull; 17/32&quot; depth &bull; 15&ndash;100 HP</strong> &bull; IC = part number (OC = IC + 4&quot;). C: classical wrapped, min. sheave 9.0&quot;. CX: cogged raw-edge, min. sheave 7.0&quot; &mdash; same sheave groove, direct upgrade.</p><p>For data centers and chief engineers: cooling tower and large AHU belt failure is a critical event. Keep C/CX spares on site. Specifying CX over C extends service intervals and reduces unplanned downtime.</p><p><strong>In stock and ready to ship.</strong> Order today for immediate shipment on all stocked sizes.</p>

<h2>Banded, Stranded &amp; Cogged V-Belts &mdash; Heavy-Duty HVAC &amp; Industrial Fan Drives</h2><p><strong>Banded V-belts</strong> are multiple V-belt strands permanently joined by a tie band, forming a single unit. They eliminate belt whip, flip, and uneven wear in high-torque, high-vibration drives where individual belts fail prematurely &mdash; cooling tower fans, large AHUs, and industrial multi-belt drives.</p><p>Available in classical (B, C), cogged (BX, CX), and cogged narrow-wedge (5VX) profiles. The number prefix indicates strand count: <strong>2/BX</strong> = two BX strands joined as one. Fits the same sheave groove as the individual equivalent &mdash; no sheave changes required. Recommended for <strong>cooling towers, large commercial fan drives, vertical shaft drives,</strong> and any multi-belt HVAC application where drive stability and consistent belt loading are critical.</p><p><strong>In stock and ready to ship.</strong> Order today for immediate shipment on all stocked sizes.</p>
