Description
Unlike the long, open-ended belts that run the length of the X and Y axes, these Circular (Ring) Timing Belts are used as the primary transmission link between the NEMA 23 (57-series) motors and the pulleys that drive the main belts.
178mm Belt (05.202.0011): A short, high-tension closed loop typically used for the Z-axis synchronization or as a direct motor-to-drive-rod coupling. It ensures that both sides of the massive vertical gantry move in perfect unison.
1140mm Belt (05.202.0010): A significantly larger closed-loop belt used to bridge the distance between the dual Y-axis drive shafts. This ensures that the left and right sides of the 800mm wide bed carriage move at the exact same rate, preventing "gantry racking" or skewing.
Features:
High Tensile Strength: Reinforced with internal fiberglass or steel cords to prevent stretching, even under the high torque generated by the 57-series stepper motors.
GT2 Profile: Features the standard 2mm pitch (GT2) tooth profile for precise, backlash-free movement and "silent" operation.
Oil & Heat Resistant: Constructed from high-quality neoprene rubber that resists the ambient heat of the 100°C heated bed and common lubricants.
Precision Tooth Geometry: Ensures a perfect mesh with the drive pulleys to eliminate tooth "jumping" during high-acceleration movements (5000mm/s).
Seamless Construction: Being "annular" (one continuous piece), there are no weak points or seams that could snap under heavy industrial loads.
