FLS flange linear guide block R165343820 REXROTH Precision Linear Ball Slider

The Bosch Rexroth R165343820 is a high-precision carbon steel ball slide block (linear slide) with a long flange design (FLS). It is part of the High Precision Ball Guide System (BSHP) series. R165343820 45 specification FLS ball slide, C3 height preload, XP precision class.
FLS is a specific specification code for slide blocks in REXROTH Linear Motion Technology systems, representing Flange, Long, and Standard height. FLS slide blocks offer extremely high rigidity and load-bearing capacity, suitable for applications with the most demanding rigidity requirements.
Key Features and Performance of FLS R1653 Ball Slider:
High Load Capacity and High Rigidity: The extended design provides a larger contact area compared to standard length sliders (such as FNS), significantly improving the ability to withstand high loads and moments.
Flexible Installation: As a flange-type slider, it supports bolt mounting from the top or bottom, suitable for various mechanical structures.
Applications: Possesses extremely high load-bearing capacity, suitable for applications with the most demanding stiffness requirements.
Smooth operation: Under external loads, it can effectively reduce friction fluctuations and provide excellent running smoothness.
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, and Electronics and semiconductor equipment.
