About This

• Size: The sewing machine belt Inner circumference 39 inches (991mm), top width 10mm/0.39in, thickness 7mm/0.27in. Precisely adapt two or more rotating shafts transmission systems witch total outer perimeter is 39 inch
• Material：Drive V-belt made of premium rubber,featuring high strength,high-temp resistance and low elongation;Grateful fatigue-resistant,capable of enduring over 10⁷ rotations;The outside fabric wrap bring higher wear resistance and transmission friction
• Reliable Performance:Sewing machine replacement belts Designed to connect rotating shafts for power transmission, with even load distribution to avoid local overload. High friction coefficient ensures no slipping during operation
• Trapezoidal Design: Trapezoidal cross-section of transmission Rubber Belt easy to install quickly,fits tightly into pulley grooves, forming a stable "wedge bite" to precise alignment and provide sufficient traction
• Applications：Rubber triangle V-belt can be used as replacement drive belt for various industrial and treadle sewing machines,e.g., flat sewing machines, overlock machines, interlock machines, buttonhole machines, waist-pulling machines, etc
