B68 V-Belt (5L710) — a classical B-section V-belt engineered for reliable power transmission in larger machinery and more demanding motor systems. With a 5/8" top width, 68" inside length, and 71" outside length, this heavy-duty belt is ideal for industrial equipment, agricultural machinery, HVAC systems, and larger compressors. Note: Inside length is about 3" shorter than outside length Key Features: Belt Type: Classical B Section (5L710 / B68) Dimensions: 5/8" top width x 13/32" height x 71" outside length Inside Length: 68" (approximately 3" shorter than outside length) Outside Diameter: 71" Angle: Standard 40° V-angle for secure grip and consistent performance Construction: Core: Features helically wound tensile cords made of high-strength, heat- and chemical-set polyester. The cords are engineered for superior tensile retention and long-term durability, tested to meet world-class performance standards. Wrap: The outer wrap is a durable synthetic rubber fabric that resists oil, heat, and abrasion. Designed for extended service life under tough operating conditions. Body: Composed of a high-performance synthetic rubber compound, formulated for flexibility, cool operation, and resistance to cracking. Strong adhesion to both cords and outer fabric ensures optimal belt integrity. Temp Range: -30°F to 140°F (-34°C to 60°C) — suitable for both indoor and outdoor use Common Applications: Larger lawn & garden equipment (riding mowers, garden tractors) Belt-driven air compressors and shop tools Agricultural equipment (combines, balers, conveyors) HVAC systems, industrial fans, and blower motors This B68 / 5L710 V-belt delivers high-performance operation with reduced noise and minimal maintenance. Ideal for heavy-duty applications where strength, reliability, and endurance are key, it's a trusted choice for OEM replacements in both commercial and agricultural settings.
