FKS R166521420 Ball Block KWD-025-FKS-C1-N-1 Flange Type Short Slider

R166521420 is a Bosch Rexroth FKS type ball runner block, with the full model number KWD-025-FKS-C1-N-1. It belongs to the Bosch Rexroth high-precision ball guide system (BSHP series) and is a high-rigidity block. Due to its short overall length, it is very suitable for automated machinery with limited lateral installation space and tight stroke requirements.

Key Advantages of the FKS R166521420 Ball Slider:

High Dynamic Characteristics: A shorter body and lower weight result in lower system inertia, making it suitable for high-speed handling, light-load, fast-cycle automated production lines or Cartesian robots.

Excellent Smooth Operation: Utilizing Rexroth's patented optimized ball inlet geometry and high-volume ball circulation, it significantly reduces elastic fluctuations during movement.

Universal Interchangeability: Rexroth ball sliders are unrestricted in their interchangeability. FKS ball sliders can be freely assembled and interchanged with all standard carbon steel or corrosion-resistant coated ball rails (such as SNS/SNO rails) of the same specifications.

The FKS R166521420 ball bearing slider, with its flange-type, short, and standard-height structure, is primarily used in automated and precision machinery where installation space is limited, response speed is fast, lateral fixation is critical, but load-bearing capacity is moderate.

Core Application Scenarios:

Automation and Robotics: Three-axis Cartesian robots, high-speed gantry robots, cylinder/motor pushrod guides

Electronics and Semiconductor Manufacturing: PCB drilling/placement machines, chip testing and sorting machines, screen dispensing/film application machines

Packaging and Logistics Machinery: Bag making and sealing machines, labeling machines, multi-row sorting systems

Medical and Laboratory Automation: Blood/sample analyzers, medical imaging equipment
