Performance Data
Mechanical Characteristics
Fine size stability, low tension in advance and low axial load, low noise, highly anti-wear, non-maintenance, positioning precision, line speed up to 80 m/s.
Chemical Property
Resistant to hydrolysis, ozone, ultraviolet, aging, grease, gasoline, acid and most solvents.
Temperature Range
-10°C ~ +80°C (110°C in short time).
Purchase & Customization
Standard packaging: 100m/roll.
Cut to length according to customer needs.
Standard width synchronous belt — no steel wires or grooves exposed on both sides, and the steel wires are arranged in a straighter manner.
Cut to width according to customer requirements; there may be a steel-wire trough on both sides and the straightness may not be as good as the standard width.
