  • ♛【Durable & Stable Material】: All the bearing ball are made of high quality chrome steel, and bearing steel balls have become irreplaceable core components in modern machinery industry through the perfect balance of high hardness, low friction, high precision, and high reliability.They are fully round shape and surface polished smooth.
  • ♛【Precision Engineering】: Each ball in our set has undergone fine polishing treatment, with a smooth surface that can reduce running resistance and ensure smooth operation. Fine and accurate size can be applied in different places. No additional polishing treatment is required, and the best performance is immediately achieved after installation.
  • ♛【Simple Maintenance】: Regular cleaning, use a soft cloth to gently wipe away dust and oil stains adhering to the surface. After cleaning, apply an appropriate amount of lubrication. You can choose to add 2-3 drops of engine oil or apply a small amount of butter to form an effective protective oil film. Keep dry during storage, apply anti rust oil and seal to avoid moisture. During maintenance, a light rotation inspection should be carried out, manually rotating the components slowly to sense the smoothness of operation. If any abnormal phenomena such as abnormal noise or jamming are detected, they should be replaced in a timely manner.
  • ♛【Wide Applications】: Steel ball bearings engineered for ball applications across diverse valve types. These versatile components serve dual purposes: providing robust bearing support and transmission functionality for industrial machinery, while also functioning as precision hardware accessories for drawer slides and door locks in furniture applications. Enhanced with oil-resistant properties, our bearings additionally meet the demanding requirements of automotive component manufacturing.

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.
