MECCANIXITY Flexible Coupling Shaft 15mm to 16mm 53mm x 44.5mm Motor Coupler Joint

Description

Product Overview

The MECCANIXITY Flexible Coupling Shaft is a precision‑engineered component designed to bridge the gap between motor output shafts and driven equipment with maximum efficiency. Constructed from high‑grade 45# steel, the shaft provides exceptional hardness and wear resistance, ensuring a long service life even in demanding industrial environments. The coupling features a 15mm to 16mm bore diameter range, allowing it to accommodate a variety of motor sizes, while the overall length of 53mm and an outer diameter of 44.5mm deliver a compact yet powerful connection. Threaded ends in both M5*0.8 and M6*1.0 sizes enable secure fastening to motor flanges and driven shafts, eliminating the need for additional adapters. The spider‑type flexible design incorporates five evenly spaced slots, each 5mm wide, which absorb torsional vibrations and compensate for minor misalignments, reducing stress on both the motor and the driven mechanism. This combination of material strength, dimensional versatility, and flexible architecture makes the MECCANIXITY coupling an ideal solution for a wide range of motion control applications.

Usage

Designed for versatility, this coupling is suitable for integration into servo motor assemblies, stepper motor drives, encoder mounts, and screw‑driving systems. It excels in machine platforms where precise alignment is critical, such as CNC routers, 3‑D printers, robotic arms, and automated conveyor systems. The high‑hardness steel construction ensures reliable torque transmission in high‑speed applications, while the flexible spider design mitigates the effects of axial and radial misalignment, extending the lifespan of both motor and driven components. Installation is straightforward: simply align the bore with the motor shaft, insert the coupling, and tighten the M5 or M6 threaded fasteners to the recommended torque. The coupling’s compact dimensions allow it to fit within tight mechanical envelopes, making it a preferred choice for equipment where space constraints and performance reliability are paramount.

FAQ

What types of motors are compatible with this coupling?

The coupling is compatible with servo motors, stepper motors, and encoder shafts that have a bore diameter between 15mm and 16mm. It is also suitable for any equipment that requires a 53mm length spider coupler.

How does the flexible spider design improve performance?

The spider design features five slots that allow the coupling to flex under load, compensating for minor axial, radial, and angular misalignments. This flexibility reduces stress on the motor bearings and extends the overall lifespan of the drivetrain.

Can the coupling be used in high‑speed applications?

Yes. The high‑hardness steel material and precise machining ensure stable torque transmission at high rotational speeds, making it ideal for applications such as CNC spindles and high‑speed robotics.

What is the recommended torque for the M5/M6 threaded fasteners?

For M5 fasteners, a torque of 2.5 Nm is recommended, and for M6 fasteners, a torque of 4.0 Nm provides a secure fit without over‑tightening. Always refer to the motor manufacturer’s specifications for final torque settings.

Is there a warranty or support available?

MECCANIXITY offers a one‑year limited warranty covering manufacturing defects. Our technical support team is available to assist with installation guidance, troubleshooting, and any other inquiries you may have.
