The R165343920 ball slide is a high-precision, high-rigidity ball slide from Bosch Rexroth's FLS series, model code KWD-045-FLS-C3-U-1. It is commonly used in linear motion systems with stringent requirements for positioning accuracy and load capacity. The 45 size flange-type long ball slide R165343920 features a no-preload (C0) and high-precision (H) design, with a CS steel body, providing high rigidity and high load capacity.
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
