The Rexroth R166589320 is an FKS short-flange ball linear slider, compatible with 20-size SNS20 and SNO20 guide rails. It employs a compact short-body flange through-hole mounting structure, offering flexible installation and minimizing space occupation.
Features of the R166589320 Ball Slider Mounting Structure
The R166589320 slider features a short slider structure, providing compact axial installation space, suitable for compact modules and small workstations where longitudinal length is limited.
It has a bottom through-hole flange, allowing for screw fastening from both the top and bottom, enabling flexible upright/inverted installation.
With an assembly height of 30mm and moderate lateral dimensions, multiple sliders can be densely arranged without interference.
It is compatible with 20-size SNS/SNO standard guide rails, and sliders of the same size are interchangeable.
Applicable Scenarios
R166589320 sliders are used in equipment with limited axial space, requiring flange installation, and offering high precision, low noise, and smooth low-speed operation: 3C automation, small slides, robotic arms, woodworking equipment, and small-format laser cutting worktables.
