BRINGSMART 2pcs 7mm Flange Coupling with Wrench High Hardness Shaft Connector Rigid Axis Model Coupler Fitting for Motor 50KTYZ 60KTYZ DIY Parts (7MM, 1)

Description

Product Overview

The BRINGSMART 7mm flange coupling is engineered for high‑hardness performance in demanding power transmission environments. Constructed from fine‑plated steel, the coupling undergoes a heat and electro‑plating process that enhances its structural integrity and provides excellent insulation. The inner diameter of 0.24″ (6mm) and outer cylinder diameter of 0.39″ (10mm) allow it to fit a wide range of motor shafts, while the base diameter of 0.87″ ensures a stable mounting platform. Each package contains two couplings, eight M4 set‑screw fasteners, and a precision wrench, giving users everything needed for a complete installation without additional purchases.

Usage

Designed for model shaft connections, this rigid set‑screw coupling excels in RC model motor applications, hobbyist robotics, and small‑scale industrial projects. Its anti‑oil and anti‑rust treatment makes it suitable for environments where exposure to lubricants or moisture is common, ensuring long‑term reliability. Users can quickly secure the coupling to motor shafts using the included M4 screws and wrench, achieving precise alignment that minimizes vibration and wear. Whether you are building a custom drone, a 3D printer extruder, or a laboratory apparatus, the coupling provides a dependable link that transfers torque efficiently.
