Analysis: Advantages of linear motion ball bearings

   For linear motion ball bearings, the structure is equipped with a retainer inside the outer ring (click to view the introduction of the installation configuration of the imported bearings), the retainer is equipped with a plurality of steel balls, and infinite loop motion. Both ends of the retainer are fixed by inner spring retaining rings, and a notched window is provided on the straight track of each steel ball to work. This part is to make the loaded steel ball into rolling contact with the shaft. With a very low friction coefficient relative to the movement, so the linear motion ball bearings are the most suitable bearings for mechanical equipment, automation equipment, energy-saving equipment.

Linear motion bearings are now more and more widely used in general or special machinery industries such as electronics, machinery, instruments, robots, tool machinery, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, CNC machine tools, automobiles, etc. in.

Advantages of using linear motion ball bearings:

  1. Since the flow contact makes the starting friction resistance and the dynamic friction resistance extremely small, energy can be saved and a high moving speed can be easily obtained.

  2. The load is increased, but the friction coefficient is not sensitive. Therefore, under heavy load, the friction coefficient is extremely small, and the accuracy is maintained for a long time, and the mechanical service life can be maintained for a long time.

3. Linear motion bearings are interchangeable, easy to install and use, time-saving, and make the mechanical structure novel, small, and light.

4. Save oil supply procedures to simplify lubrication and maintenance.

      5. Bearings with oil seals on both sides are also suitable for use in places where there is a lot of dust or foreign matter is easily invaded.

How to clean imported bearings

Regular cleaning is very important in the process of using imported bearings. So how to properly clean the imported bearings? Let me introduce it to you.

     When the imported bearings are removed for inspection, the appearance records are first recorded by photography. Also, verify the amount of lubricant remaining and sample the lubricant before cleaning the bearings.


     The cleaning of the bearings is carried out by rough washing and fine washing, and a metal mesh frame can be placed on the bottom of the used container.

     When rough washing, remove grease or adhesive with a brush or the like in the oil. At this time, if the bearing is rotated in the oil, be careful that the rolling surface will be damaged by foreign matter or the like.

     When cleaning, the bearing is slowly rotated in the oil and must be carefully carried out.

     The cleaning agent generally used is a neutral non-aqueous diesel oil or kerosene, and a warm alkali liquid or the like is sometimes used as needed. Regardless of which cleaning agent is used, it is often filtered and kept clean.


     Immediately after cleaning, apply anti-rust oil or anti-rust grease to the imported bearings. 80,000 to 100,000 hours.

The motor uses ceramic bearing technology...

Precision ceramic bearings are a masterpiece of improved bearings in terms of manufacturing materials. The shaft core precision-processed with ceramic material powder has benefited from the high strength, high hardness and high temperature resistance of the precision ceramic material, which greatly prolongs the service life of the bearing. Precision ceramic bearings are widely used in various small motors, typically represented by DC fans, small pumps, and optical storage equipment spindle motors. The fan life of this bearing is even higher than that of a double ball bearing fan, which can reach 80,000 to 100,000 hours.

Stone engraving machine rust processing tips

The lacquer worker urgently removes the rust method, and the second is the physical method of rust removal: by means of skill knocking, shovel, scraping, brushing, sand or flexible frustration to eliminate surface rust and scale. It is also the most succinct way to use a blade, a scraper, a pointed hammer, a wire brush, an abrasive cloth, a broken saw blade, and the like.
If the maintenance is not timely, the stone engraving machine is due to the working environment. The spindle motor is very simple and rusty. The slight rust does not affect the normal operation of the spindle motor. However, if it is not processed for a long time, the life of the spindle motor will be shortened. Jinan Jingwei stone engraving machine gives several simple ways to remove rust:
Uniform spray on the motor, a chemical method to remove rust: can use WD-40 cleaning lubricant. About half an hour, you can use a cotton cloth to wipe off the rust on the stone engraving machine. If the rust is fierce, you can get a few more times. WD-40 is non-conductive and has excellent lubrication.

How to maintain the engraving machine daily

In order to help us better extend the life of the engraving machine dust cover, we will introduce the daily maintenance of the engraving machine dust cover today, and we hope to assist us.

1, daily viewing
