The Bosch Rexroth KWD-020-FLS-C0-N-1 is a robust, high-performance flange-mount ball runner block designed for demanding linear motion applications requiring rigidity, stability and smooth operation. The FLS configuration (flange width, long block length, standard block height) provides exceptional mounting stability and increased load distribution thanks to the extended block length. Built from durable carbon steel and supplied pre-lubricated, this block is ideal for industrial automation, CNC machinery, robotics and precision positioning systems.
Key Features
-
FLS design (Flange / Long length / Standard height) — wide flange base gives excellent mounting stability; long block length improves stiffness and reduces deflection.
-
Size 20 — engineered for higher load demands compared to smaller rail sizes.
-
Carbon steel construction — maximises strength, reliability and service life under continuous load.
-
C0 preload (preload-free) — delivers smooth, low-resistance motion ideal for applications where minimal rolling friction is preferred.
-
Accuracy class N — offers dependable, general-purpose precision for a wide range of industrial machinery.
-
Standard sealing (SS) — provides reliable protection from dust and typical contaminants.
-
Pre-lubricated & sealed — ready to install upon arrival, requiring no initial maintenance.
-
High load and torque capacities — suitable for applications with varying force directions and single-block-per-rail usage.
-
Compatible with Bosch Rexroth size-20 FLS, FNS and SNS rails.
