Characteristics of plastic bearings bushings

Plastic bearings bushings are a kind of linear motion system with self-lubricating characteristics. The biggest difference between them and metal linear bearings is that metal linear bearings are rolling friction, and there is point contact between the bearing and the cylindrical shaft, so this kind of low-load high-speed motion; while plastic bearings bushings are sliding friction, and there is surface contact between the bearing and the cylindrical shaft, so this kind of system is suitable for high-load medium and low-speed motion.

Plastic bearings bushings are allowed to be used in dusty occasions because of the chip removal groove design inside. Dust is automatically brought out of the friction surface of the bearing body from the chip removal groove during movement; plastic linear bearings can also be cleaned during use, and the internal sliding film made of special materials can even be used for long-term operation in liquid.

Plastic bearings bushings are high-performance materials specially developed for dry operation; the special patented structural design allows the bearing to run smoothly in dirt, dust or sand, and the spiral structure design allows the dirt to fall into the designed groove very quickly, and finally be taken out of the groove through continuous linear motion. The linear bearing system, while the traditional metal rolling linear bearings are prone to jamming, ball running and other phenomena in the presence of dirt, dust or sand, and even cause the shaft to be strained due to jamming.

The continuous use temperature of linear bearings is -40 to +100 degrees, ◆ self-lubricating and maintenance-free, ◆ low friction coefficient, wear resistance, ◆ smooth operation without noise, ◆ corrosion resistance, normal operation in liquid cleaning fluid, ◆ dirt resistance, excellent chip removal design, ◆ convenient installation and maintenance design; it has the advantages of low friction coefficient, wear resistance, chemical resistance, smooth operation without noise, etc. It is a new type of linear bearing product.
