Smooth Belt - 1/8D (8.0 ID)

Discontinued

A smooth (round) rubber belt for use with pulley-based drive systems in robotics and mechanical projects. The elastic construction applies tension when stretched across pulleys, creating excellent grip. Compatible with Actobotics and similar robotics building systems.

Specifications

  • Profile – 1/8″ diameter (round/smooth)
  • Inner Diameter – 8.0″
  • Durometer Hardness – A70
  • Temperature Range – −35°F to 250°F (−37°C to 121°C)
  • Stretch Factor – 12–26%
  • Material – Rubber

Key Features

  • Elastic Tension – Applies grip force when stretched across pulleys
  • High-Grip Rubber – Excellent traction between belt and pulley
  • Wide Temperature Range – Suitable for indoor and outdoor applications
  • Versatile – Works with various pulley sizes within stretch range
Tip: A lower stretch factor (12%) applies less side-load to axles with less friction. A higher stretch factor (26%) provides more resistance to belt deflection but increases axle side-load.

Ideal For

  • Robotics pulley drives and linear actuators
  • Follow focus systems
  • XY tables and 90-degree drives
  • Robot tracks and battery hold-downs

Package Contents

  • 1× Smooth Belt (1/8″ D, 8.0″ ID)
