The Bosch Rexroth B.RUNN. BLOCK NRII KWD-030-FNS-C2-P-0 (R200172204) is a highly precise and corrosion-resistant ball runner block designed for demanding linear motion applications. This component is part of the Ball Rail Systems product group and features a Resist NRII construction, ensuring durability in harsh environments, including exposure to water-based media, acidic materials, alkali or saline solutions, as well as high humidity and temperatures. The runner block boasts an FNS format with medium preload (class C) and precision accuracy (class P), tailored for applications requiring high rigidity and maximum precision. It lacks a ball chain, initial lubrication, preservation, and attachment elements on both front edges. The body of the runner block is made from corrosion-resistant steel compliant with DIN EN standards. With an overall length of . mm, the runner block can be interchanged with guide rails of every accuracy class. It supports long-term lubrication over several years and offers excellent dynamic characteristics due to its optimized entry-zone geometry that increases travel accuracy by up to six times. Key specifications include a straight lube connection loosely attached for ease of maintenance and a height of . mm for the runner block. The system allows for self-alignment to compensate misalignments without the need for a ball chain. Its friction coefficient ranges from 0., ensuring smooth operation under various conditions. The dynamic load capacity (C) and dynamic torsional moment load capacity (Mt) are determined based on DIN ISO standards, accounting for travel distances commonly stipulated in industry applications. The product is available in multiple common sizes to cater to different requirements. In summary, this Bosch Rexroth ball runner block stands out due to its robustness against corrosion, interchangeability with SNS Ball Guide Rails across all accuracy classes, and superior performance characteristics that make it suitable for clean rooms, printed circuit board manufacturing, packaging industry applications, among other high-precision linear motion systems.
