Product Description

Linear bearings are usually composed of a bearing sleeve, steel balls, a cage, and a shaft. The inner surface of the bearing sleeve has multiple arc-shaped raceways, in which the steel balls roll. The cage is used to maintain the uniform distribution of the steel balls, allowing them to roll smoothly between the shaft and the bearing sleeve, thereby achieving linear motion.

Linear bearings work based on the principle of rolling friction. When the shaft moves in a straight line in the bearing sleeve, the steel balls roll between the shaft and the raceway of the bearing sleeve, converting sliding friction into rolling friction, greatly reducing frictional resistance and enabling the shaft to move in a straight line with high precision and low friction. Meanwhile, due to the point contact between the steel ball and the raceway, it can withstand a certain radial load.
