The FKS R166579320 ball slide block is a flange-type, short, standard-height ball slide block, commonly used in automated equipment, machine tools, laser equipment, etc., where longitudinal space is limited but high load capacity and rigidity are required.
The R166579320 flange-type slide block has a medium load capacity and is suitable for applications with limited longitudinal space. The slide block can be installed from above or below.
Key features of the R166579320 FKS standard height ball block:
Flange-short (FKS) structure: Wider block width, good installation rigidity, and small footprint, suitable for compact equipment designs.
Four-row ball circulation design: Utilizes a four-row ball contact design, achieving medium load capacity in radial, reverse radial, and lateral directions.
High-precision guidance: Smooth operation with high positioning accuracy and repeatability.
Equipped with sealing and lubrication system: Standard end face seal and optimized internal lubrication channels effectively prevent contaminant ingress and extend service life.
Core Application Scenarios:
Automation and Robotics: Three-axis Cartesian robots, high-speed gantry robots, cylinder/motor pushrod guides
Electronics and Semiconductor Manufacturing: PCB drilling/placement machines, chip testing and sorting machines, screen dispensing/film application machines
Packaging and Logistics Machinery: Bag making and sealing machines, labeling machines, multi-row sorting systems
Medical and Laboratory Automation: Blood/sample analyzers, medical imaging equipment
