Basic structure and composition: Sliding body: 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 element rotates in a circle between the guide rail and the slider to achieve precise linear motion. Type differences: Ball type: point contact, low friction, high speed, suitable for precision under light loads (such as 3D printers). Roller type: linear contact, high load capacity, high rigidity.
Key Performance Features: Good rigidity: Thanks to the preload design (such as increasing the ball diameter), it resists vibration and impact. Low friction: The coefficient of friction is only 1/50 of that of the sliding guide rail, which saves energy and reduces temperature rise. Long service life: The steel guide rail and seal design allow for thousands of kilometers of travel.
Typical application areas: CNC machine tools: tool feed, spindle drive. Automation equipment: robotic arm joints, transport and positioning in assembly lines. Precision instruments: semiconductor lithography machines, measuring equipment. Civil applications: 3D printer nozzle movement, adjustment of electric lifting platforms.
Selection and maintenance points, load capacity: Calculate the axial force and torque, and select the corresponding rated load (the dynamic C value should have 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 in humid environments. Installation accuracy: It is necessary to calibrate the parallelism of the guide rail. Maintenance points: Clean the guide rail regularly, add grease (such as lithium-based grease), and avoid dry friction.
