In recent years, the application field of engineering plastic products has been expanding, among which plastic linear bearings have attracted much attention as engineering plastic products with broad application prospects. Plastic linear bearings have excellent performance and can work well even under poor lubrication conditions, so they are very suitable for use as bearings and have great potential.
Features of plastic linear bearings
High strength: Plastic linear bearings are made of high-strength, wear-resistant engineering plastic materials, which have excellent tensile strength and wear resistance, and can withstand large loads.
Corrosion resistance: It has good corrosion resistance, can work well in wet, corrosive media, and will not rust or corrode.
Lightweight: Due to the low density of plastic materials, plastic linear bearings have the characteristics of lightweight, which can reduce the weight of mechanical equipment and improve operating efficiency.
Low noise: The friction coefficient of plastic linear bearings is low, and the noise generated during operation is small, which reduces the operating noise of mechanical equipment and improves the comfort of the working environment.
Specifications for plastic linear bearings
In the specifications of plastic linear bearings, there are several different series: LM, LME, LIN-11 and LIN-12, KH. These series offer a wide range of options for different regions and installation needs.
The LM series is a plastic linear bearing that is widely used in Asia and Southeast Asia. This series is one of the most commonly used linear bearing series in Asia according to metric sizes. The tolerance of the outer diameter of the linear shaft is generally H7 to ensure a tight and stable connection with the shaft.
The LIN-11 series is a plastic linear bearing that meets European standards. The series features circlip limit mounting, which can be easily fixed to the mounting hole, providing a reliable mounting method. Compared to the LIN-11, the LIN-12 series is a narrow design that is mounted directly with the outer diameter and the mounting hole. This design is mainly designed to save installation space and is suitable for applications where installation space is limited.
The KH series is another common series of plastic linear bearings. The KH series features the use of plug spacers to adjust the preload of the bearing, resulting in better bearing performance. This makes the KH series bearings suitable for applications where precise adjustment of the preload is required.
Mounting requirements for plastic linear bearings
Clean environment: Before installing plastic linear bearings, it is necessary to ensure that the installation environment is clean, dust-free and free of foreign objects, so as not to affect the normal operation of the installation and bearings.
Bearing lubrication: According to the specific requirements, select the appropriate lubricant to lubricate the bearing, ensure that the bearing can work normally during operation, and reduce friction and wear.
Installation accuracy: In the installation process, it is necessary to ensure the matching accuracy between the shaft and the bearing seat, to ensure that the shaft can move smoothly on the bearing, and to avoid problems such as jamming and deflection.
Fixation: After the installation is completed, the bearing needs to be fixed to ensure that the connection between the shaft and the bearing is firm and reliable, and to avoid the bearing from loosening or falling off.
