The Mitsuboshi S3M Rubber Timing Belt is part of Mitsuboshi’s “SUPER TORQUE G” series of synchronous drive belts. The “S3M” designation indicates a 3 mm tooth pitch, making it suitable for applications that require a balance between compact size and moderate torque transmission. It is larger than the ultra-fine S2M belt but smaller than large-pitch belts, allowing for efficient power transfer in medium-precision systems.
| Name | Length [mm] | Width [mm] | Pitch [mm] | Number of Teeth |

The S3M belt is made of chloroprene (neoprene) rubber reinforced with fiberglass cords, providing high tensile strength while maintaining flexibility. Its teeth are covered with nylon fabric to reduce wear and ensure smooth engagement with pulleys. This construction offers quiet operation, minimal backlash, and long service life, making it reliable for continuous or repetitive motion systems.
The 3 mm pitch and robust design make the S3M belt ideal for small- to medium-sized machinery, automation equipment, printers, conveyors, and other devices requiring precise synchronous motion. It can replace chain or gear drives in many systems, offering quieter, cleaner, and lower-maintenance operation while still transmitting moderate torque efficiently.
