FAQ

Q1: How to choose the material of 2M synchronous belt pulley?
A: Choose according to the scenario requirements:
Aluminum alloy: High speed and light load scenarios (such as 3D printers), fast heat dissipation, and lightweight.
Stainless steel: in humid/corrosive environments (such as food processing equipment).
Engineering plastics (PA66/POM): Low noise, low-cost requirements (such as office automation equipment).

Q2: How to prevent the synchronous belt from deviating or falling off during installation?
A: Ensure the following two points:
The pulley and motor shaft are strictly aligned coaxially, and the radial runout is calibrated using a dial gauge (recommended to be less than 0.05mm).
Prioritize choosing pulleys with double-sided flanges to limit the lateral displacement of the synchronous belt.
