Importance of linear Motion Bearing Maintenance in Operation to Service life

Motion Bearing is a type of high-performance rolling element bearing designed to provide smooth and accurate motion in various industrial applications. This type of bearing typically consists of a cylindrical or spherical inner and outer raceway, with a series of either balls or rollers placed between them.

The unique design of Motion Bearings allows for the transmission of both radial and axial loads, making them suitable for applications that require precise motion control, such as in robotics, medical equipment, and semiconductor manufacturing. These bearings are available in various sizes and designs, including linear motion bearings, rotary motion bearings, and complex motion bearings, among others.

Motion Bearings are made from high-quality materials, such as stainless steel or ceramic, to provide high durability, long service life, and low maintenance requirements. In summary, Motion Bearings offer high precision, low friction, and reliable performance for a wide range of industrial applications.

If the linear motion bearing is well lubricated and correctly blocks sundries and moisture, it means that the oil seal should not be worn However, when opening the bearing housing, check the bearing and regularly check the oil seal Check the condition of oil seals near the bearing to ensure that they are sufficient to prevent hot liquid or corrosive liquid or gas from penetrating into the bearing along the axis.
If the oil seal is worn, replace it as soon as possible.Importance of linear Motion Bearing Maintenance in Operation to Service life
High temperature often indicates that the bearing is in abnormal condition High temperatures are also harmful to lubricants in bearings Sometimes bearing overheating can be attributed to the lubricant of the bearing If the linear motion bearing operates for a long time at a temperature of more than 125 ℃, the service life of the bearing will be reduced.Importance of linear Motion Bearing Maintenance in Operation to Service life
The causes of high-temperature bearing include insufficient or excessive lubrication, magazine contained in lubricant, excessive load, bearing damage, insufficient clearance, high-temperature friction caused by oil seal, etc
Check the condition of the running machine and monitor it to avoid equipment shutdown
In the stage of bearing selection, many factors (such as load, hardness, operating environment, etc.) need to be considered. A good linear motion bearing design will first make the bearing reach its large life value.Importance of linear Motion Bearing Maintenance in Operation to Service life
For correct storage, linear motion bearings should be kept in their original packaging before installation. It needs to be kept in a clean, moisture-free and relatively constant temperature environment. Shaking and vibration may permanently damage the mechanical properties of the bearing, so vibration should be avoided during handling and storage.Importance of linear Motion Bearing Maintenance in Operation to Service life
Generally, bearings should be stored horizontally. Some heavier bearings will be deformed due to their own weight after being placed vertically for a long time!Importance of linear Motion Bearing Maintenance in Operation to Service life
In addition, grease coated (or sealed) linear motion bearings need special care because the density of grease will change after long-term storage. When the bearing is used for the first time, there will be a certain degree of rotation noise. Therefore, the shelving time of such bearings should be controlled according to the principle of first in first out!

Cleaning, which is very important for bearings. The rotating surface of linear motion bearing ring is very smooth and sensitive to damage caused by pollutants. Particulate impurities will be over rolled by rolling elements and produce local pressure in the bearing, which will eventually lead to permanent material fatigue.
When fully equipped and reinstalled, the linear motion bearing should be carefully installed and disassembled with appropriate tools You should choose the right tool! Industry estimates that 16% of premature bearing failure is caused by incorrect installation. Generally speaking, suitable bearing installation equipment will be adopted for large-scale installation.

The synthetic radial load on the fixed load is exposed from the local ring raceway fixed ring and transmitted to the corresponding shaft or bearing. The characteristic of this load is that the radial load vector is a relatively static synthesis and ring. The load bearing ring can be used relatively loose.

The rotating load is the full loaded cylindrical roller bearing ring acting on the synthetic radial load on the drum rotating along the circumferential direction. The rotating parts, such as the rotating burden, are borne by the synthetic vector phase ring radial load rotation.
The rotating load ring fits closely. In special cases, the load, if selected, is a light or heavy load at low speed. Only occasionally, the ring, bearing adopts hard material and high surface roughness. The rotating load bearing ring can also be used to be relatively loose.
The direction of the combined load in the third rolling ring is determined by the direction of the load acting on the rolling ring, and the radial load or the load in the rolling ring is not constant. To bear the load swing, the outer ring and circumference, bearing and hole should be used closely.
The common methods to adjust the radial clearance of fully loaded cylindrical roller bearings are as follows:Importance of linear Motion Bearing Maintenance in Operation to Service life
The side clearance of cylindrical and oval bearing shells can be adjusted by manual grinding and scraping or by adding pad on the bearing split and scraping after turning.Importance of linear Motion Bearing Maintenance in Operation to Service life
The top clearance of cylindrical and oval bearing shells can be adjusted by manual grinding and scraping or adding pad to the bearing split when circumstances permit.Importance of linear Motion Bearing Maintenance in Operation to Service life
In principle, it is not allowed to scrape and adjust the clearance of multi oil wedge fixed bearing bush. If the clearance is inappropriate, replace it with a new one.Importance of linear Motion Bearing Maintenance in Operation to Service life
For multi oil wedge tilting bearing bush, it is not allowed to scrape the pad. If the clearance is not appropriate, replace the pad. For tile with adjustable thickness, the amount of tile can be adjusted by adjusting the stainless steel pad on the back of the tile or reducing the thickness of the adjustment block.
Note that for the multi oil wedge tilting bearing bush, the thickness error between the same group of pads shall be less than 0.01mm.Importance of linear Motion Bearing Maintenance in Operation to Service life.
