Overview
The NBK MJT-30 flexible coupling is a jaw-type shaft coupling engineered for precision power transmission in mechanical systems. This Couplicon-series unit combines flexibility with durability, accommodating minor shaft misalignment while transmitting torque smoothly. Ideal for automation equipment, pumps, motors, and driven machinery, the MJT-30 provides reliable performance in demanding industrial environments.
Key Features
- Jaw-type flexible design absorbs vibration and compensates for minor misalignment
- Set screw or keyed mounting options for secure shaft attachment
- Compact 1-3/16" outside diameter for space-constrained installations
- Durable aluminum or steel construction for long service life
- Selectable bore sizes to match your shaft diameter requirements
- Drop-in replacement for standard MJT-30 applications across industrial equipment
Technical Specifications
The MJT-30 is manufactured to precision engineering standards with multiple bore and mounting configurations. Standard bore options typically range from 6mm to 14mm, accommodating common shaft sizes in industrial automation. Mounting styles include set screw-only, set screw with key, and fully keyed variants. The coupling’s lightweight design reduces rotational inertia while maintaining rigidity and torque capacity suitable for general industrial duty cycles.
Typical Applications
- Conveyor and material handling system drives
- Machine tool motor to spindle connections
