Oil-Free LM12 Plastic Linear Bearing For 3D Printer

Plastic linear bearings are a kind of linear motion system with self-lubricating characteristics. The biggest difference from metal linear bearings is that metal linear bearings have rolling friction, and the bearing and cylindrical shaft are in point contact, so this is suitable for low-load and high-speed motion; Plastic linear bearings are sliding friction, and there is surface contact between the bearing and the cylindrical shaft, so this type is suitable for high-load, low-speed movement. Plastic linear bearings have no special requirements for matching shafts; they can withstand greater loads than metal bearings, but because the movement between the bearing and the shaft is sliding friction, the speed of plastic linear bearings is limited to a certain extent; the movement resistance is higher than that of metal linear bearings. The bearing is larger; but its motion noise is lower than that of metal linear bearings, especially in the case of medium and high speed, the influence of the noise of plastic linear bearings with speed is very small. Plastic linear bearings have a chip groove design inside, so they are allowed to be used in places with heavy dust. The dust will automatically be brought out of the friction surface of the bearing body from the chip groove during movement; plastic linear bearings are also allowed to be used during use It can even be used for long-term operation in liquids for cleaning. The overall dimensions are exactly the same as ordinary linear bearings Features: All plastic structure, easy to maintain, can be used in liquid, dusty occasions advantage: No jamming, corrosion resistance, dust resistance, abrasion resistance, waterproof, Lubrication-free, light weight, low noise, non-magnetic, insulated
