The Bosch Rexroth B.RUNN. BLOCK NRII KWD-015-FNS-C2-P-0 (R200112204) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and precision. This product is part of the Ball Rail Systems and is made of Resist NRII, a material that provides excellent corrosion resistance, making it suitable for use in harsh environments with exposure to water-based media, acidic materials, alkali, saline solutions, and high humidity levels above 70%. The block's body and all steel components are crafted from corrosion-resistant steel according to DIN EN standards. The runner block features a size 15 profile with an FNS format, indicating a flanged width, normal length, and standard height. It has a medium preload (class C) and falls under the precision accuracy class P. It does not include a ball chain or any initial lubrication and comes without attachment elements or preservation measures. The runner block offers superb rigidity for demanding tasks, with an overall length of 63 mm. This model can be used on all SNS Ball Guide Rails and is available in five common sizes. It boasts excellent load ratings in all four main loading directions due to its design featuring four rows of balls with point contact that minimizes friction. Its dynamic characteristics are enhanced by an optimized entry-zone geometry that increases travel accuracy up to six times compared to conventional designs. For lubrication purposes, it includes lube fittings with metal threads on all sides and features a minimum quantity lubrication system with an integrated reservoir for oil lubrication. The runner block's height is 24 mm when combined with the guide rail. This Bosch Rexroth ball runner block is ideal for applications requiring maximum precision over long-term use without frequent maintenance needs. It's particularly well-suited for clean rooms and printed circuit board manufacturing due to its corrosion-resistant properties but also serves well in general packaging industry applications where reliability and performance are critical.
