16T5-455+2 Yellow PU coated timing belts for Wire EDM Machines，This is the most common application for this specification. In wire cutting machines, it provides precise power transmission for the wire-feeding mechanism or tensioning system.
Precision Gripping: The 2mm-thick pressure layer provides a stable, elastic contact surface for the electrode wire (molybdenum or copper wire).
Vibration Damping: The thickened black PU layer absorbs micro-vibrations caused by the motor’s high-frequency rotation, ensuring smooth wire movement and thereby improving the surface finish of the workpiece.

Industry-Specific Advantages of Wire Harness Cutting Machines
1. “Flexible Gripping” with a 2mm Thickened Layer (The +2mm Advantage)
When feeding wire harnesses, cutting machines must ensure no slippage occurs without leaving indentations on the wire insulation. This 2mm thickened layer (typically made of Linatex rubber or ultra-soft PU) provides critical cushioning and friction:
Mark-Free Conveyance: Even extremely fine or soft silicone wires can be gripped without damage.
High Coefficient of Friction: Ensures the wire harness does not shift during high-speed starts and stops (accelerated stripping/cutting).
2. Precise Pitch Control (Synchronization)
The T5 tooth profile combined with a steel core ensures zero belt elongation during high-frequency reciprocating motion. This directly determines the accuracy of the wire cutting machine’s set length—if the belt stretches or contracts, the cut wire lengths will be inaccurate.
3. Oil Resistance and Durability
Wire harness processing environments often involve trace amounts of lubricating oil. Yonghang’s PU material possesses inherent oil resistance and will not swell or become sticky upon contact with oil, unlike ordinary rubber belts, significantly extending maintenance intervals.
