10mm-14mm Plum Shaft Coupling Tyenaza 30mm×40mm for CNC 3D Printer

Description

Product Overview

The Tyenaza 10mm‑14mm plum shaft coupling is engineered for precision power transmission in demanding industrial environments. Constructed from high‑grade aluminium alloy with a surface oxidation treatment, the coupling delivers exceptional hardness and resistance to wear while maintaining a lightweight profile. Its compact dimensions—30 mm outer diameter and 40 mm length—fit seamlessly into tight mechanical assemblies, and the plum‑shaped design provides a large contact area that distributes load evenly across the shaft. The coupling tolerates speeds up to 10 000 rpm and a maximum torque of 12.5 Nm, making it suitable for high‑speed CNC spindles, 3D printer extruders, and servo‑driven actuators. The flexible nature of the coupling absorbs vibration, reduces shock loads, and compensates for radial, angular, and axial misalignment, thereby extending the lifespan of both motor and driven components.

Usage

Designed for a broad range of applications, this coupling excels in environments where precision and reliability are paramount. In CNC machining centers, it connects the motor to the spindle, ensuring smooth rotation and minimizing backlash during high‑speed cutting operations. For 3D printers, the coupling links the stepper motor to the extruder gear, delivering consistent filament feed while dampening the vibrations that can cause print artifacts. Servo‑driven robotic arms benefit from the coupling’s ability to handle rapid direction changes without transmitting harmful shock to the motor. The coupling’s simple installation—requiring only a set‑screw on each shaft—allows technicians to quickly replace or upgrade components, reducing downtime. Its versatility also makes it suitable for pumps, fans, and other rotary equipment where alignment tolerance and torque transmission are critical.

FAQ

What shaft sizes can this coupling accommodate?

The coupling is designed for input and output shafts ranging from 10 mm to 14 mm in diameter, allowing it to be used with a variety of stepper motors, servomotors, and small DC motors commonly found in CNC and 3D printing equipment.

Can the coupling be installed without special tools?

Yes. Installation requires only a standard hex wrench to tighten the set‑screws on each shaft end. The design includes keyways that align the coupling quickly, so you can secure it in a matter of minutes without the need for specialized equipment.

How does the coupling handle misalignment?

The flexible plum design provides up to 0.5 mm of radial, 0.5° of angular, and 0.2 mm of axial compensation. This elasticity reduces stress on bearings and motor shafts, preventing premature wear and maintaining smooth operation even when the connected components are not perfectly aligned.

Is this coupling suitable for high‑speed applications?

Absolutely. The aluminium alloy material and balanced geometry allow the coupling to operate safely at speeds up to 10 000 rpm, making it ideal for high‑speed spindles, fans, and other rotary devices that require reliable torque transmission at elevated revolutions.

What warranty and support are offered?

We provide a one‑year limited warranty covering material defects and workmanship. Our technical support team is available via email and phone to assist with installation guidance, troubleshooting, and any other inquiries you may have after purchase.
