The Bosch Rexroth B.RUNNER BLOCK AL (R163211322) is a high-precision aluminum ball runner block designed for use with SNS ball guide rails, offering an optimal balance between reduced weight and robust performance. This runner block is part of the linear guide system and features a slimline width, normal length, and standard height to accommodate a range of industrial applications. The aluminum construction ensures less gravity impact compared to steel versions, making it suitable for lightweight design considerations. The R163211322 boasts a low preload (Preload class C), high accuracy (Accuracy class H), and comes with a ball chain that facilitates quiet and smooth motion. It arrives prelubricated with roller bearing grease Dynalub, promoting long-term maintenance-free operation. The straight lube connection is loosely attached for ease of access. With its optimized entry zone geometry and high ball count, the runner block minimizes variations in elastic deflection, thus enhancing travel accuracy by up to six times. It's engineered to compensate for low tolerances in connected structures, ensuring maximum precision even in demanding scenarios. This model is characterized by excellent dynamic characteristics and supports minimum quantity lubrication via an integrated oil reservoir. It can be used interchangeably with all SNS ball guide rails within the same accuracy class, providing flexibility in system design. Pre-drilled holes facilitate pinned fitting for precise alignment. The Bosch Rexroth B.RUNNER BLOCK AL is designed to handle dynamic loads efficiently while maintaining low noise levels during operation due to its well-designed ball return system. With its ability to withstand various ambient temperatures and its compatibility across different profiled rail systems sizes (E, H, K, B), this runner block caters to diverse industrial requirements where high precision and lightweight design are paramount.
