- Rubber STS standard: S4.5M, S3M, S2M, S1.5M
- Only S5M, S8M, S14M have HP-STS type
- High transmission torque: Due to unique tooth profile
- Low noise, even at high speeds
- Long life: Due to the meshing of the wire teeth and pulley, bending fatigue is reduced, leading to increased life.
- No lubrication or re-tensioning required
- Space saving: Belt and pulley width can be designed narrower because of high transmission power, thus the machine is designed more compactly
