Basic function Linear motion bearings enable mechanical parts to perform smooth linear reciprocating motion. The core uses rolling balls to reduce friction, providing a smoother move. They are commonly used in printers, automated production lines, and similar systems, replacing traditional sliding guides to improve movement quality. Core advantages Friction is significantly lower than sliding friction, making operation less laborious and more energy efficient. Rolling elements are evenly distributed, resulting in low vibration and low noise during movement. Stable performance across a wide range of speeds, maintaining smooth operation at both and low speeds. Main categories Ball type (for example LM series). The ball type is small in size and in precision, suitable for light loads and speed (such as precision instruments). The latter category offers higher loadbearing capacity and is suitable for heavy load scenarios (such as heavy conveying equipment). Key use scenarios Precision instruments and metrology devices that require accuracy and repeatable, smooth motion. Printers, scanners, and automated imaging systems where quiet, consistent carriage movement is important. Automated production lines and conveying equipment that demand reliable, lownoise operation under varying loads.
