The Bosch Rexroth B.RUNN. BLOCK NRII KWD-035-FNS-C1-H-0 (R200131304) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and precision. The runner block, part of the Ball Rail Systems, is made from Resist NRII material which is a corrosion-resistant steel compliant with DIN EN standards, making it suitable for environments with water-based media, diluted acids, alkalis, saline solutions, or high humidity above 70% and temperatures exceeding 100°C. This model features size 35 with an FNS format indicating a flanged width, normal length, and standard height. It boasts high accuracy (class H) and low preload (class C), ensuring smooth motion and reduced system wear without a ball chain. The runner block body comes in a standard version with an overall length of 140 mm. It is designed to be interchangeable with guide rails of every accuracy level. The product offers excellent dynamic characteristics due to its optimized entry zone geometry and a high number of balls that minimize variation in elastic deflection. Its dynamic load capacity C is determined based on a 100 km travel as per DIN ISO standards. For applications requiring long-term lubrication, it features a minimum quantity lubrication system with an integrated reservoir for oil lubrication. Furthermore, the B.RUNN. BLOCK NRII KWD-035-FNS-C1-H-0 has the same high load ratings in all four main loading directions and can accommodate maximum accelerations up to 50 m/s² without initial lubrication or preservation. Seals like the standard SS seal are used to prevent ingress of contaminants that could reduce service life while maintaining low friction for ease of movement. Overall, this Bosch Rexroth ball runner block is well-suited for applications demanding rigidity, maximum precision over years of use, and reliable operation even in challenging environmental conditions.
