Snapmaker XY-Axis Timing Belts 3.5m | Z-Axis Timing Belt for U1

Description The XY-Axis Timing Belts Kit provides the high-tensile drive loops required to handle the extreme kinetic loads of the Snapmaker U1's high-speed CoreXY motion layout, because the U1 moves its toolheads rapidly at accelerations up to thousands of mm/s. The Z-Axis Timing Belt is a specialized closed-loop synchronization belt designed to link the independent vertical Z-axis lead screws or lifting rods on the Snapmaker U1 chassis. Unlike the open-ended XY belts that experience continuous fast acceleration shifts, the Z-axis loop handles the heavy load of holding and raising the entire build platform structure evenly. Features XY-Axis Timing Belts Kit Genuine Snapmaker OEM Spec: Molded to match the exact tooth profile and structural depth of the native U1 pulley array, preventing skipping. Fiberglass-Reinforced Core: Features internal braided fiberglass tension cords that prevent structural stretching or elongation over long-term, high-tension usage. Low-Friction Tooth Fabric: The neoprene tooth faces are lined with a wear-resistant composite cloth to reduce friction, lower noise levels and extend belt life. 3.5m Spool Length: Provides a single continuous cut that easily accommodates the full length required to replace both primary drive loops in the CoreXY system. Z-Axis Timing Belt Seamless Closed-Loop Design: Formed as a factory-joined continuous loop, eliminating splice points to deliver smooth, uniform rotational tracking. High-Torque Load Tolerance: Engineered with a wider structural profile to handle the constant heavy down-force of the heated bed frame assembly without slipping. Perfect Dual-Pulley Alignment: Keeps multiple lead screws rotating in unison, eliminating bed sagging or shifting on one side during a print. Drop-In Maintenance Swap: Pre-sized to fit the physical structural spacing of the U1 base chassis frame, allowing you to slide it over the drive teeth without custom trimming.
