R166589322 Ball Runner Block Four-way Equal Load Slider KWD-020-FKS-C1-H-1

R166589322 is a 20-size high-rigidity ball linear guide slider, belonging to the FKS flange type short slider. It adopts a four-row ball circulation structure and a low-noise ball chain design, featuring high load capacity, high precision, smooth operation and long service life. It is suitable for high-precision linear motion applications such as CNC machine tools, automation equipment, precision modules and semiconductor equipment.

Features of R166589322 FKS Ball Slider:

Four-Directional Equal Load Capacity: Rated load is consistent in all four force directions (up/down, left/right), providing strong resistance to overturning and eccentric loading. Even single sliders can be used stably with short strokes.

Built-in Ball Retaining Chain: Balls will not scatter, easy to install and disassemble. High-speed ball bearings are evenly distributed, ensuring balanced load and extended lifespan.

Patented Ball Inlet Curved Surface: Smooth ball entry, significantly reducing friction and vibration, resulting in quiet operation; maximum linear velocity 5m/s, acceleration 500m/s², stable high-frequency reciprocating motion.

Medium Rigidity + Compact Load Capacity: Short, lightweight design; dynamic load 14700N, static load 15300N; small size, high load capacity.

The R166589322 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.
