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 performs cyclic 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 light load precision (such as 3D printers). Roller type: linear contact, large load capacity, high rigidity.
Main performance characteristics: Good rigidity: due to the preload design (such as increasing the ball diameter), it can resist vibration and impact. Low friction: the friction coefficient is only 1/50 of that of the sliding guide, saving energy and cooling. Long life: steel guides and seals can achieve thousands of miles of travel.
Typical application areas: CNC machine tools: tool feeding, spindle drive. Automation equipment: articulation, conveying and positioning of robot arms on assembly lines. Precision instruments: semiconductor lithography machines, measuring equipment. Civilian applications: movement of 3D printer nozzles, adjustment of electric lifting platforms.
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) at high speed. 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

Exquisite craftsmanship
Easy to assemble
Slide or guide rail can be replaced separately
Installation Notes
During installation, please do not remove the plastic false rail in the slider in advance, otherwise it will easily cause the steel balls in the slider to fall off and cannot be installed normally! During disassembly, the false rail can also prevent the balls from falling off!
