## Overview

This pack of two 10mm to 14mm shaft couplings features a 40mm length and 32mm diameter, crafted from durable aluminum alloy with screw-type clamping. Designed for zero backlash and flexible misalignment absorption, they optimize performance in 3D printers, CNC machines, and other light to medium duty drive systems.

## Description

Description:10mm to 14mm shaft usage diameter, 40mm length, 32mm diameter, set screw type, beam coupling.Zero backlash. One-piece metallic spring coupling. For little torque shaft connect.Absorption of parallel, angular misalignments and shaft end-play by spring action.Widely used in drive systems for encoders, instrumentation,lead screws, small pumps, feed rollers and anywhere light to medium duty, torsionally flexible coupling is required. Specification:Feature: Screw type (coiling clamping)Size: 40x32mm/ 1.57x1.26inch( L*D)Material: Aluminum alloyMain Color: Silver toneWeight: 132g Package Content:2 x Shaft coupling

Review: A very useful for my CNC - Works perfectly to be able connect my Nema 34 motors to the ball screw which has a shaft of 10mm
Review: material choice will crack under long term use, steel would be better. - aluminum fatigues in the long run, it is stiff, but not stiff like steel.

## Features

- Shaft Usage: 10mm to 14mm / 0.39 to 0.55 inch
- Material: Aluminum alloy; Size: 40x32mm/ 1.57x1.26inch( L*D)
- Feature: Screw type (coiling clamping); Main Color: Silver tone

### ⭐⭐⭐⭐⭐ A very useful for my CNC
*by R***. on March 31, 2025*

Works perfectly to be able connect my Nema 34 motors to the ball screw which has a shaft of 10mm

### ⭐⭐⭐⭐ material choice will crack under long term use, steel would be better.
*by D***S on January 30, 2023*

aluminum fatigues in the long run, it is stiff, but not stiff like steel.

### ⭐ NOT TO SPEC
*by C***E on September 23, 2022*

These are oversized. The 14mm side is actually 15.44mm and once tightened down all the way it is 14.86mm. Doesn't even begin to grip a 14.0mm diameter shaft. Unfortunately the return window has passed so I'm stuck with them.
