<h2>5VX V-Belts — Cogged Narrow Wedge Belts for Commercial HVAC & Data Centers</h2><p>The <strong>5VX cogged V-belt</strong> powers large commercial HVAC systems, data center cooling infrastructure, and industrial fan drives where uptime is not optional. <strong>21/32" top width • 17/32" depth • Cogged raw-edge • 10–100 HP • Min. sheave 5.5"</strong> • Numbered by OC ÷ 10 (5VX1000 = 100.0" OC), IC = OC − 4".</p><p>Runs cooler and lasts longer than standard 5V belts. Preferred by chief engineers and data center facilities teams for large AHU, cooling tower, and precision cooling drives where belt failure is a critical event.</p><p><strong>In stock and ready to ship.</strong> Order today for immediate shipment on all stocked sizes.</p>
<h2>A / 4L V-Belts — HVAC Air Handler & Blower Drive Belts</h2><p>The <strong>A/4L V-belt</strong> is the most widely replaced belt in HVAC service. Found in light commercial air handlers, residential furnaces, small blowers, and exhaust fans. <strong>1/2" top width • 5/16" depth • 1/4–10 HP • Min. sheave 3.0"</strong> • A-section: IC = part number (OC = IC + 2") | 4L: OC = part number ÷ 10. Same cross-section, same sheave — direct substitutes when lengths match.</p><p>Stock A38–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 — 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 — same 1/2" × 5/16" cross-section, same sheave, measurably better performance. <strong>Cogged raw-edge • 1/4–10 HP • Min. sheave 2.2"</strong> • IC = part number (OC = IC + 2").</p><p>Up to <strong>30% more power capacity</strong>. Runs cooler. Lasts longer. Operates on sheaves as small as 2.2". 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 — Commercial HVAC Air Handler & Rooftop Unit Belts</h2><p>The <strong>B/5L V-belt</strong> is the single most common drive belt in commercial HVAC — rooftop units (RTUs), air handling units (AHUs), packaged systems, and condenser fan drives. <strong>21/32" top width • 13/32" depth • 1–25 HP • Min. sheave 5.4"</strong> • B-section: IC = part number (OC = IC + 3") | 5L: OC = part number ÷ 10. Same cross-section — direct substitutes when lengths match.</p><p>Stock B45–B75 range to cover the majority of commercial RTU and AHU service calls. A failed blower belt takes down an entire zone — 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 — 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 — the most common belt in commercial HVAC. Drop-in replacement, same sheave, no modifications. <strong>21/32" top width • 13/32" depth • Cogged raw-edge • 1–25 HP • Min. sheave 4.0"</strong> • IC = part number (OC = IC + 3").</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 — 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 — Heavy-Duty Commercial HVAC & Industrial Drive Belts</h2><p><strong>C and CX V-belts</strong> power the largest drives in commercial HVAC — large-capacity AHUs, cooling tower fan drives, industrial exhaust fans, and heavy-duty blower systems. <strong>7/8" top width • 17/32" depth • 15–100 HP</strong> • IC = part number (OC = IC + 4"). C: classical wrapped, min. sheave 9.0". CX: cogged raw-edge, min. sheave 7.0" — 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 & Cogged V-Belts — Heavy-Duty HVAC & 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 — 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 — 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>
