1PCS DA8M Double-Sided Timing Belt 1960mm x 40mm Rubber Drive Belt for 3D Printer CNC Machine Upgrade, Industrial Equipment Replacement Part

The DA8M double-sided timing belt is characterized by precise transmission ratio, compact structure (enabling dual-sided synchronous drive with a single belt, saving space), high efficiency (due to double-sided meshing drive), and easy maintenance, achieving efficient, stable, and space-saving transmission.The DA8M double-sided timing belt is a type of HTD (High Torque Drive) timing belt with a circular arc tooth profile and a pitch of 8mm. "DA" indicates that the teeth on both sides of the belt are arranged symmetrically.Belt Material:​ Primarily uses rubber as the base material, effectively resisting dirt and moderate moisture.Provides high strength and tensile resistance.Ensures dimensional stability and minimal deformation during operation.Model Identification:​ DA8M belt models typically follow the format "DA8M - Pitch Length" (e.g., DA8M-2880). The pitch length is directly related to the number of teeth, calculated as: Pitch Length = Number of Teeth × Pitch (8mm).Important Precautions!Installation & Alignment:​ Ensure the two pulleys are parallel and their faces are aligned to prevent belt run-off and wear.Never Pry On:​ Absolutely prohibit​ prying the belt onto a pulley with tools, as this can damage the tensile cords. Adjust the center distance and install the belt by hand.Proper Tension:Too Loose:​ Prone to tooth jumping and rapid wear.Too Tight:​ Increases bearing load and risk of belt breakage.After Run-in:​ Re-tension the belt after the first 24-48 hours of operation.Environment:​ Keep the drive area clean. Avoid environments that may degrade the rubber.Storage:​ Store in a cool, dry place. Lay flat or hang. Do not fold. Keep away from heat sources and direct sunlight.
