About this item

  • 【Package & Size】2 pieces Flange Coupling Connector; 3mm(0.12 inch) inner Dia 10mm(0.39 inch) external diameter; Net Weight: 25g(0.88 oz).
  • 【Material】The coupling connector is Exquisite iron plating chromium,maded of C45 Carbon Steel (it is better than copper and aluminum alloys), thereby improving the toughness and corrosion resistance of the rigid flange coupling, electroplated process make it sturdiness and insulation, striking shaft more stable and easy for installment and replacement.
  • 【High precision】The shaft coupling is made of high-precision technology, which can realize the tight connection of the 2 shafts, and the model machine is not easy to separate during the operation.
  • 【Low inertia】Shaft coupler is so highly sensitive that can quickly switch the working state, efficient and swift.
  • 【Wide application】Flange coupling is a special coupling that can fix a shaft to a flat surface and can easily install other accessories on the shaft, widely used in model shaft connection, perfect accessories for RC model motors, etc.

FAQ

What types of products does Stemora offer?


Stemora offers supplies for science experiments, microscopy, biology learning, measurement, laboratory organization, electronics, robotics, coding education, 3D printing, maker projects, and classroom activities. Available products and specifications may change over time.

Are Stemora products suitable for children?


Recommended ages vary by product. Please review the product description, manufacturer guidance, included warnings, and required skill level before purchasing. Products containing small parts, tools, electrical components, glass, or chemicals may not be suitable for young children.

Is adult supervision required?


Adult supervision is recommended for children and students, especially when using electrical components, sharp tools, heated equipment, glassware, small parts, or experiment materials. Customers are responsible for following all product instructions and safety precautions.

Can these products be used at home and in classrooms?


Many products may be suitable for classrooms, home learning, science projects, maker spaces, and hobby activities. Suitability depends on the specific product, learning environment, user experience, and intended activity.

How can I check what is included with a product?


Please review the product title, description, specifications, images, package quantity, and included-components section before ordering. Items shown for demonstration or scale in product images may not always be included.

How do I know whether an electronic or robotics part is compatible?


Check the listed dimensions, voltage, connector type, board compatibility, operating requirements, and supported platforms. Compatibility is not guaranteed unless it is specifically stated on the product page. Contact us before ordering if you need clarification.

When will I receive tracking information?


Tracking information is generally provided within 3–5 business days after an order is confirmed. In some cases, processing may take approximately 7–8 business days. Delivery may require an additional 4–5 business days after tracking becomes available, depending on the carrier and destination.
