Basic structure and composition: Sliding body: A component that moves along the guide rail and contains rolling elements (such as balls, rollers or wheels).
Working principle: Rolling friction replaces sliding friction, and the rolling body moves in a circular motion between the guide rail and the slider to achieve precise linear motion. Type difference: Ball type: point contact, low friction, high speed, suitable for precision motion under light load (such as 3D printers). Roller type: linear contact, high load capacity, high rigidity.
Main performance characteristics: Good rigidity: thanks to the preload design (such as increasing the ball diameter), it is resistant to vibration and impact. Low friction coefficient: The friction coefficient is only 1/50 of that of the sliding guide rail, which saves energy and reduces temperature. Long life: The steel guide rail and seal design can achieve a travel of thousands of kilometers.
Typical application areas: CNC machine tools: tool feeding, spindle drive. Automation equipment: robotic arm joints, assembly line conveying and positioning. Precision instruments: semiconductor lithography machines, measuring equipment. Civilian applications: 3D printer nozzle movement, electric lifting platform adjustment.
Selection and maintenance points, load capacity: calculate the axial force and torque, and select the corresponding rated load (dynamic C value should leave a margin). Speed and acceleration: pay attention to the lubrication method (grease or oil circulation) in high-speed situations. Environmental applicability: IP54 or higher protection level is required in dusty environments, and stainless steel is required in humid environments. Installation accuracy: The parallelism of the guide rail needs to be calibrated. Maintenance points: clean the guide rail regularly, add grease (such as lithium-based grease), and avoid dry friction.
