Linear Ball Bearing

What Are Linear Ball Bearings?

The linear ball is bearings, also known as linear ball bearing slides or linear motion ball bearing, uses linear motion to guide machine elements along a cylindrical shaft with as little friction as possible.

Because the bearing ball is in point contact with the bearing jacket, the steel ball rolls with the least frictional resistance. Therefore, the linear bearing has low friction, is relatively stable, does not change with the bearing speed, and can obtain smooth linear motion with high sensitivity and accuracy.

Where Are Linear Ball Bearings Used?

The structure of linear motion ball bearing is that a retainer is installed in the outer ring. The retainer is equipped with multiple steel balls, and it moves in an infinite loop. What is a linear bearing used for? Linear motion bearings are increasingly widely used in electronics, machinery, instruments, robots, tool machinery, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, CNC machine tools, or particular machinery industries such as automobiles.

This part is to make the loaded steel ball make rolling contact with the shaft. Innerspring retaining rings fix both ends of the retainer. Notched windows are provided on the linear rails where the steel balls work under force. Relatively move with a very low coefficient of friction, so linear motion ball bearings are the most suitable for mechanical equipment, automation equipment, and energy-saving equipment.
