FLS R165342320 Medium Preload High Precision Ball Screw

The Bosch Rexroth R165342320 ball slide is a 45 flange-type extended high-precision ball slide (FLS). R165342320 FLS ball block features a carbon steel structure, H precision, C2 medium preload, achieving high rigidity, low friction, and heavy load capacity, making it suitable for high-precision, high-load linear motion applications.
REXROTH FLS long ball slides are widely used in industrial applications where stability is paramount:
  • High Rigidity: Their extended design effectively reduces frictional fluctuations during operation, providing excellent smoothness.
  • Heavy Load Capacity: FLS ball slides are suitable for CNC machine tools, large automated assembly lines, robots, and heavy material handling systems.
  • High Compatibility: The slides and guideways are interchangeable, allowing users to freely combine different specifications of slides and guideways within the same accuracy class, greatly facilitating logistics and maintenance.
Rexroth ultra-high load capacity ball slides FLS are primarily used in the following industries:
  • Machine tools
  • Industrial automation and robotics
  • Precision packaging and printing machinery
  • Assembly and conveying technology
  • Electronics and semiconductor equipment
Highlights of Rexroth REXROTH ball slides:
  • Interchangeability with ball guide systems
  • Optional integrated wear-free sensing measurement system
  • Various accessories
  • Top mounts can be bolted on from the top and bottom of the ball slide
  • Increased stiffness under lifting and lateral loads by additional bolts secured in two holes in the center of the ball slide
  • All accessories are equipped with end-face fastening threads
  • High stiffness in all load directions - suitable for applications with only one slide per track
  • Integrated fully sealed
  • High torque load capacity
  • Optimized inlet geometry and a large number of balls minimize changes in elastic deflection
  • Smooth, noiseless operation due to optimized ball and ball chain return and guidance design
  • Various preload levels
