Bosch Rexroth R166529322 Linear Ball Slider of Automated Equipment

R166529322 is a high-precision steel ball linear guide slider from Bosch Rexroth, Germany. Its official complete technical model number is KWD-025-FKS-C0-H-1. This slider belongs to the FKS series (flange type, short version, standard height) and is designed for linear automated drive scenarios with limited space and requiring high precision.

R166529322 Ball Slider Performance Characteristics

H Precision-grade accuracy, high positioning accuracy; C0 No preload clearance type, smooth operation, low resistance, no crawling at low speeds.

Four-way equal load design, anti-eccentric load, standard seal, effectively prevents contaminants from entering and extends service life.

Quenched and precision-ground raceways, long wear-resistant life, capable of high-speed reciprocating operation, suitable for precision automation, lasers, and small machine tools.

The R166529322 ball bearing slider (20mm size, short flange FKS, with ball retaining chain) is widely used in the following industrial fields due to its short structure and ultra-smooth motion characteristics:

Space-constrained structures: Specifically designed for compact machinery where longitudinal installation space is limited, ordinary sliders cannot be accommodated, but bidirectional flange fixation is required.

Semiconductor and electronics manufacturing: Due to the built-in ball chain, friction fluctuations and noise are significantly reduced, making it commonly used in chip placement machines, wafer handling, and PCB inspection equipment requiring micron-level stable positioning.

Medical and automation equipment: With extremely low operating noise and long-lasting lubrication, it is widely used in medical analytical instruments, surgical robot arms, and multi-axis Cartesian coordinate robotic arms.

High-precision machining and 3D printing: Its excellent torsional rigidity and minimal movement pulsation effectively eliminate machining marks, making it an ideal choice for precision CNC micro-engraving and industrial-grade 3D printers.
