NBK Japan MJC-14-ERD is a jaw-type flexible coupling designed to join shafts while absorbing eccentricity and angular misalignment in precision drive systems. It’s commonly used in servo motors, small CNCs, and automation assemblies where smooth torque transfer matters.

✅ Bore 1: 3/16 in (4.76 mm); Bore 2: 6.35 mm (0.25 in)
✅ Outer diameter: 14 mm (0.551 in); Length: 22 mm (0.87 in)
✅ Material: stainless steel; single piece pack; Made in Japan
✅ Backlash: zero-backlash at low torque; precise torque transfer
✅ Flexible: bellows design absorbs eccentricity, angular misalignment, and end-play
✅ Easy fit: smooth hub and sleeve assembly

💡 What is a jaw-type flexible coupling used for in precision drive systems?

Jaw-type flexible couplings connect shafts while accommodating misalignment and vibration in light-to-medium torque setups.

  • They compensate for small angular misalignment, parallel offset, and end-play to protect the drivetrain
  • Constructed in stainless steel with electrical insulation for safe, durable operation
  • Ideal for servo motors, CNCs, and automation where smooth, quiet power transmission is needed

This handy solution reduces shaft stress and improves positioning accuracy, helping extend equipment life in daily manufacturing or hobby-grade projects.
