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: 10mm /0.4inch; External diameter: 7mm /0.3inch; Internal diameter: 3mm / 0.1inch;
  • 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.


Description：
1. Provides linear Ball Bearing with seals on both sides to prevent ingress of dirt, water, and foreign matter.
2. Linear Motion Bearing (also called Ball Bushing or Shaft Guiding) is a rolling friction supporting element that is usually used for linear motion mechanical parts with small friction.
3. Coordinate with Linear Motion Shaft, recirculating balls provide unlimited stroke at low friction movement
4. It is great for 3D printers, CNC, and other applications.

Decent price, and quick shipping, but not smooth bearings at all. Using on a joystick, so it would have been nice to get smooth rolling bearings. But they do work.
