The Bosch Rexroth B.RUNNER BLOCK AL (R163111422) is a high-precision aluminum ball runner block designed for linear motion applications requiring lightweight yet robust guides. This model features the FNS size format, which includes a width flange, normal length, and standard height. The runner block body is crafted from aluminum, offering a significant weight advantage over traditional steel variants without compromising on strength or durability. The R163111422 comes with a low preload (Preload class C) and standard accuracy (Accuracy class N), ensuring smooth motion with minimal play. It is equipped with a ball chain that contributes to low noise operation and superior travel behavior. The patented entry zone design of this runner block significantly enhances travel accuracy by up to six times compared to conventional systems. For ease of maintenance and longevity, the B.RUNNER BLOCK AL features initial lubrication and preservation with the roller bearing grease Dynalub. It also boasts improved rigidity under lift-off and side loading conditions due to additional mounting screw holes at the center of the block. Furthermore, attachments can be mounted from both above and below the runner block. The R163111422 has been prelubricated at the factory for immediate use and includes an integrated reservoir for oil lubrication to support minimum quantity lubrication strategies. The dynamic load capacity C and dynamic longitudinal moment load capacity ML are based on a 100,000 m travel as per DIN ISO standards, ensuring reliable performance over extensive operational periods. This Bosch Rexroth ball runner block is versatile in its application with interchangeability features allowing it to be combined with guide rails of every accuracy level. It is particularly suitable for lightweight designs where compensating for low tolerances in connected structures is necessary. With its extracompact design, maximum precision, high torque load capacity, and long-term lubrication capabilities spanning several years, this model stands out as an exceptional choice for various industrial automation tasks.
