The Bosch Rexroth B.RUNNER BLOCK CS KWD-035-FNS-C2-N-1 (R165132420) is a ball runner block designed for high precision linear movement in mechanical systems. This component is part of the ball rail system product group and is notable for its FNS size format, which indicates a flanged width, normal length, and standard height. The runner block body is constructed from unalloyed steel CS, ensuring durability and reliability. This model features a medium preload class C and an accuracy class N, which denotes a normal level of precision. It does not include a ball chain but comes with initial lubrication and preservation for ease of use right out of the box. The roller bearing grease used is Dynalub, which provides excellent lubrication properties. The B.RUNNER BLOCK CS has an overall length of 90 mm and can be used interchangeably with guide rails of every accuracy level within the material profiled rail systems. Its design allows for self-aligning to compensate for any misalignments within the system but does not include self-alignment features. It has a dynamic load capacity C, static load rating C0, dynamic torsional moment load capacity Mt, and static longitudinal moment load capacity ML—all calculated based on a 100 km travel as per DIN ISO standards. The maximum permissible linear speed (vmax) and acceleration (amax) are specified to ensure optimal performance within its operating temperature range from -10°C to +100°C. The runner block's friction coefficient ranges between 0.01 to 0.02 without seal friction included, ensuring smooth motion transfer with minimal resistance. It features standard seals SS for protection against contaminants. With a weight of 0.3 kg and nominal size specifications tailored for various industrial applications, this Bosch Rexroth runner block is engineered to deliver consistent performance in linear motion tasks while accommodating potential misalignments within the mechanical assembly it serves.
