1-Pack 615H Rubber Timing Belt, 75mm Wide H-Type Synchronous Belt for Industrial Machinery, Automotive Engines, CNC Equipment, Printing and Textile Machinery Drive

H-Type rubber synchronous belt features trapezoidal teeth with a standard pitch of 12.7mm, tooth height of 2.29mm, belt thickness of 4.3mm, and a tooth side angle of 40°.Engineered for high-load capacity and precise power transmission, ideal for high-torque, high-speed industrial drive systems.Main rubber body offers extended resistance to aging.Fiberglass cord tension members provide superior tensile strength, excellent dynamic flex fatigue resistance, and outstanding crack resistance.Installation requires temporarily reducing the center distance between pulleys. Install the belt before resetting the distance; if a tensioner exists, loosen it first.Avoid prying: Never use tools like screwdrivers to force the belt, as this can cause hidden breaks in the fiberglass tension members.Ensure pulley shafts are parallel. Misalignment can lead to tracking issues, tooth jumping, or accelerated wear.Mounting frames must possess sufficient rigidity to prevent operational shaft misalignment and subsequent belt disengagement.Apply initial tension according to belt width specifications:Too loose: May cause slippage, tooth jumping, and reduced efficiency.Too tight: Can accelerate wear on bearings and the belt itself.Do not exceed load limits. Overloading can lead to tooth shear or joint failure.Minimize frequent start-stop cycles. Sudden tension changes can reduce service life.Regularly remove accumulated dust from the belt surface and clean pulley grooves to prevent debris from entering the mesh and damaging teeth.Periodically inspect for root cracks and edge wear.When stored off machinery, coil the belt. Do not fold, to avoid stress cracks in the rubber.Store in a cool, dry, and well-ventilated area.
