About this item

  • TWO RUBBER SEALS FOR DUSTPROOF: These ball bearings are dust-sealed with two rubber seals to prevent the ingress of dirt, water, and foreign matter.
  • FEATURES: These bearings offer smooth movement, low friction, high rigidity, and an extended lifespan. They are available in standard sizes and can be easily replaced in other sizes, providing a convenient solution for replacing worn components.
  • SIZE for LINEAR BEARINGS: As parts of linear motion systems, the linear bearings are used in conjunction with cylindrical shafts or guideways.,Length: 30mm /1.2inch; External diameter: 21mm /0.8inch; Internal diameter: 12mm / 0.5inch;
  • FUNCTION: Linear bearings are linear motion systems for use with cylindrical shafts with infinite stroke. Since the carrier ball is in point contact with the shaft, low loads are applied. The steel balls rotate with very little frictional resistance, which results in a smooth motion with high accuracy.
  • WIDE APPLICATION: Linear bearings are widely used in electronic equipment, tensile testing machines and digital three-dimensional coordinate measuring equipment and other precision equipment, as well as multi-axis machine tools, punch presses, tool grinding machines, automatic gas cutters, printers, and other industrial machinery sliding. As parts of linear motion systems, the linear bearings are used in conjunction with cylindrical shafts or guideways.

FAQ

How can I confirm that a product is suitable for my application?


Review the product description, dimensions, materials, ratings, connection types, and compatibility information before ordering. Industrial requirements vary, so consult the equipment manufacturer or a qualified professional if you are uncertain.

Do you provide installation or technical advice?


We can help clarify information shown on a product page, but we do not provide engineering, installation, or workplace-safety advice. Products should be selected, installed, and operated by appropriately qualified personnel where required.

Can I change or cancel my order after placing it?


Contact us as soon as possible at ruleindgalein@gmail.com. We will try to accommodate your request, but changes or cancellations cannot be guaranteed once an order has entered processing or shipment.

When will my order be shipped?


Processing and delivery estimates may vary depending on the product, destination, inventory availability, and carrier. Please review the shipping information provided at checkout and our Shipping & Delivery Policy for additional details.

How can I track my order?


When tracking becomes available, it will be sent to the email address used for your order. Tracking activity may take some time to appear after the carrier receives the shipment.

Why did my order arrive in more than one package?
