The Bosch Rexroth STD.LINEAR BUSHING KBM-40 (R060004000) is a high-quality standard linear bushing designed for heavy-duty applications. This closed-type bushing, made from standard metal, is engineered without seals to facilitate use in harsh environments where heavy contamination may be present, such as woodworking, foundries, and cement plants. The robust all-metal design includes a steel ball retainer that enhances durability and resistance to external elements. The KBM-40 model features numerous pockets that act as lubricant reservoirs, which can extend lubrication intervals or even allow for lifetime lubrication. These pockets also serve the crucial function of collecting any dirt or debris that could potentially cause jamming in the mechanism. For additional protection against contaminants, this linear bushing comes equipped with integrated steel retaining rings. Designed to accommodate self-supporting shafts with a diameter range specified by the manufacturer, this linear bushing uses balls made of rolling bearing steel to ensure smooth motion and reliable performance. The outer sleeve is hardened and ground for precision and longevity. The product's design allows for higher operating temperatures with larger shaft diameters due to the absence of wiper seals. With its dynamic load capacity calibrated based on a total travel distance of 100 km (and adjustable based on longer distances), the KBM-40 offers reliable performance under various load conditions. It also boasts a maximum acceleration rate as specified by Bosch Rexroth and operates efficiently within a permissible ambient temperature range. The friction coefficient of this linear bushing varies under different loads but remains within the predefined range when adequately lubricated with oil. The KBM-40's weight is provided by the manufacturer and ensures compatibility with various applications requiring robust linear motion solutions without compromising on precision or durability.
