Smooth Belt - 1/8D (2.0 ID)

A smooth (round) rubber belt for use with Actobotics pulleys and a variety of mechanical drive applications. The elastic rubber construction provides excellent grip between belt and pulley, with a stretch factor of 12–26% that allows you to control the tension applied to your drive system.

Key Features

  • Smooth Round Profile – Works with standard smooth pulleys
  • Elastic Rubber – Excellent grip and self-tensioning
  • Wide Temperature Range – −35 °F to 250 °F (−37 °C to 121 °C)
  • 12–26% Stretch Factor – Adjustable tension based on installation

Specifications

  • Cross-Section Diameter: 1/8″
  • Inner Diameter: 2.0″
  • Durometer Hardness: A70
  • Stretch Factor: 12–26%
  • Temperature Range: −35 to 250 °F
  • Part Number: 636114
Tip: Lower stretch creates less side-load and friction on axles. Higher stretch provides more resistance to belt deflection but increases axle loading.

Ideal For

  • Linear drives and XY tables
  • Follow focus systems
  • 90° drive configurations
  • Robot tracks and belt drives
