The Bosch Rexroth B.RUNNER BLOCK CR KWC-020-FNN-C0-H-2 (R169389360) is a high-precision ball runner block designed for linear motion systems where space is restricted and high accuracy is essential. This model features a Resist CR coating, providing exceptional corrosion resistance, and comes in size 20 with an FNN format, which indicates a flange width, normal length, and low height profile. It is constructed from unalloyed steel CS with a matte-silver hard chrome-plated finish. The runner block boasts high accuracy (class H) and is preload-free (preload class C), ensuring smooth motion without pre-tension. The absence of a ball chain contributes to its compact design. It has angular lube nipples loosely attached for lubrication purposes but comes preserved without initial lubrication. The overall length of the runner block is specified at . mm. This product offers interchangeability with guide rails across all accuracies, making it versatile for different applications. It provides significantly reduced frictional oscillations and low friction levels even under external loads due to its patented entry zone that enhances travel accuracy by up to six times. The B.RUNNER BLOCK CR KWC-020-FNN-C0-H-2 has been prelubricated at the factory for excellent dynamic characteristics over extended periods, supporting long-term lubrication. Additional features include end-face fastening threads for attachments, low noise levels during operation, outstanding travel behavior, and the capability to self-align to compensate for misalignments. Its dynamic load capacity C and static load rating are based on DIN ISO standards with a specified friction coefficient of 0.01...0.02 without seal friction. Overall, this Bosch Rexroth runner block is suitable for applications demanding maximum precision and durability in challenging environments with permissible ambient temperatures ranging from min ... max °C for short durations. Its robust construction and advanced design make it an ideal choice for various linear motion requirements within specified parameters.
