The R165342220 ball slide is a high-precision, high-rigidity ball slide from Bosch Rexroth's FLS series, model code KWD-045-FLS-C2-P-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 R165342220 features a preload (C2) and precision (P) design, with a CS steel body, providing high rigidity and high load capacity.
The main features of the FLS flange-type extended ball bearing slider can be summarized as follows:
High rigidity and high load capacity: The extended structure of the FLS slider increases the number of balls and distributes the force more evenly, significantly improving load capacity and impact resistance;
Good installation stability: The flange base provides a larger mounting contact surface, allowing for fastening from above or below, suitable for equipment requiring high fixing strength;
Four-way equal load capacity: The FLS flange-type slider has a consistent rated load in all directions (up, down, left, and right), adapting to complex stress conditions;
Smooth operation and high precision: Optimized ball circulation results in low friction and low vibration, suitable for high-precision linear motion systems;
Wide range of applications: Particularly suitable for applications requiring high rigidity and high stability, such as CNC machine tools, automated production lines, and heavy-duty precision equipment.
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
