The primary distinction lies in structural integrity, tension uniformity, and high-speed operational reliability:
| Belt Type | Structural Feature | Key Performance & Best Fit |
|---|---|---|
| Seamless Endless Belts | Continuous vulcanization without any splice or joint. Fully integrated core matrix. | Provides perfectly uniform tension, zero weak points, eliminates high-frequency vibration, and significantly extends service life. Highly recommended for high-speed, high-precision industrial applications. |
| Jointed Flat Belts | Features mechanical or chemical overlap/splice points. | Spliced areas act as inherent stress concentrations that risk fatigue, cracking, or catastrophic failure under extreme high tension or rotational speed. |
