5-Pack 70XL Timing Belts, 30 mm Wide, for 3D Printers and CNC Machines

Description

• Precise fit for 35-tooth pulleys, designed for XL pulleys for seamless replacement without alignment issues.
• Oil- and wear-resistant rubber compound withstands temperature fluctuations and deformation.
• Precise power transmission at high torque minimizes slippage and maintains synchronization under load.
• Quiet, low-maintenance operation with low operating noise and lubricant-free use.
• Industrial-grade impact resistance handles overloads and cyclic bending for long-term stable performance.

Precise synchronous drive The trapezoidal teeth engage precisely with the pulleys to ensure a constant transmission ratio. Compact space-saving design Compatible with small pulleys to save installation space, ideal for office equipment. Reinforced tensile layer Fiberglass reinforcement increases tensile strength and resistance to bending fatigue, extending service life. High-quality elastomer The aging-resistant rubber compound provides flexibility and lateral stability while reducing vibration at high speeds. Reduced-noise operation The optimized design minimizes operating noise and vibration transmission. Installation and Maintenance Critical instructions: - If the center distance is adjustable, reduce it before installation and restore it after fitting the belt. - If a tensioner is present, loosen it before installation and retension it afterward. - Never install the belt by force. Hidden damage to the tensile layer can shorten its service life. - Align the pulley shafts parallel to each other. Misalignment can cause belt tracking problems or tooth wear. - Align the teeth precisely. The teeth must engage fully in the grooves to prevent stress concentrations. - After installation, turn the pulley by hand to check for uniform tooth engagement. Tension adjustment: - Too little tension: slipping, inaccurate power transmission, and accelerated wear. - Too much tension: belt overstretching, tensile-layer fatigue, and premature failure. Maintenance: - Remove surface dust regularly and clean deposits from the grooves to protect against tooth damage. - Check for cracks at the tooth roots and wear along the edges. - Store the belt coiled after removal; never fold it, as folding can cause stress cracks in the rubber. - Storage location: cool and well ventilated.
