CAD data of S8M150/250/300/400 timing pulley
The S5M keyless high‑torque synchronous pulley is a standard‑type, keyless shaft sleeve pulley designed for high torque applications. It is offered with standard‑type keyless sleeves (ST) and SH sleeves, allowing average torque multipliers of 1.2‑2.5× compared with conventional sleeves.
The document lists belt width options, material selections, surface‑treatment hardness, shaft bore sizes, and maximum allowable torque values. CAD file references and ordering codes are also provided for engineering use. This manual is written in Chinese.
