CoograDrive® Hollow 8mm - Type 1

CoograDrive®

Hollow 8mm - Type 1

Technical Supply Specifications

Features

  • Transmission ratio optimized to speed
  • Hollow shaft thru center of rotational axis
  • Preloaded ball bearing
  • Lifetime lubrication
  • High reliability

Description

The CoograDrive® Hollow 8mm - type 1 micro gearbox combines minimal outer dimensions with optimum torque capacity. In addition, a hollow shaft is realised in the tiny installation space which allows optical or electrical signals to be guided through the central rotary axis of the gear. At the core of this durable micro gearbox is a low-backlash CoograDrive® gear with a reduction ratio of 40:1.
