A linear guide is a type of linear motion transmission system used in industrial equipment and machinery. Its primary function is to support and guide motion in a straight line. Typically, a linear guide consists of a rail and a carriage. The rail is mounted on the base or frame of the equipment, while the carriage is attached to the component requiring linear movement. The system enables precise straight-line motion in both vertical and horizontal directions through the use of ball bearings or sliding mechanisms.

1. After operating for a period, it may be found that indentations appear on the track of the linear guide rail, and the slider's steel balls are cracked. What is the reason?

Generally, this is because the load is too large, causing the steel balls to leave the track, which results in cracking of the steel balls and continuous damage to the track. In this case, you can consider replacing the slider with a larger one, for example, replacing a 20-sized slider with a 25-sized one, or increasing the number of sliders to reduce external loads and change the installation method to reduce the bearing capacity on one side. If the problem is due to lubrication, you can consider using another type of lubricating oil to increase lubrication and reduce the lubrication interval. It is necessary to regularly check whether there are foreign objects entering the guide rail. If there are foreign objects, it is necessary to improve the sealing parts or add dust-proof accessories.

2. Why do the steel balls fall out of the slider after operating for some time?

Iron filings falling from the ball groove cause damage to the steel balls, ending their service life, resulting in fatigue and excessive load on the surface of the steel parts. It may also be due to excessive load, incorrect installation, or only one side bearing the torque. All these situations may cause the steel balls to fall off.

3. After the slider has been running for some time, it is found that the bearing end cover and the end dirt-proof device are deformed or cracked. Why?

Incorrect installation methods will cause only one side of the slider and the track to bear the force. It may also be caused by external force damage, resulting in deformation or cracking of the bearing end cover and the end dirt-proof device. For sliders with poor internal conditions, you can change the dirt-proof system, replace it with other lubricating greases, increase the amount of lubricating oil, and reduce the lubrication interval. Attention should be paid to the installation angle during installation. The improvement of product assembly needs to be done by professional and skilled engineers to avoid damage to the linear guide rail slider.
