The Bosch Rexroth ELINE BALL BUSHING KBC-30-DD-RT-G (R065825544) is a high-quality linear bushing designed to facilitate smooth and precise linear motion in various applications. This compact model, belonging to the eLINE LB Series Compact C, features a shaft diameter of 30 mm and is equipped with two seals for enhanced protection against contaminants. The bushing boasts reduced radial clearance, making it suitable for applications requiring minimal-clearance bearings with an H bore. Engineered for general requirements, this low-cost linear bushing offers small outer dimensions and a highly compact construction. It has a high dynamic load rating and an extended service life due to its hardened segmental load-bearing plates with ball conformity in the running track. The initial lubrication is provided by Dynalub, which contributes to its low maintenance needs. The ELINE BALL BUSHING KBC-30-DD-RT-G supports high travel speeds of up to 5 meters per second and can operate within an ambient temperature range of -20°C to +80°C. Its outer diameter D measures 47 mm, ensuring a secure fit in the housing bore without additional retention. The integrated metal retainer is approximately 1.85 mm larger than the shaft diameter, further contributing to its stability. This linear bushing's design includes many pockets that act as lubricant reservoirs for extended intervals between re-lubrication or even lubrication for life, depending on usage conditions. These pockets also serve to collect any dirt ingress, preventing potential jamming of the bushing. With POM ball retainers and balls made of rolling bearing steel, the product ensures durability and consistent performance. In terms of load capacities, this model has a minimum dynamic load capacity (Cmin) based on a total travel distance of 100 km; however, when based on 50 km travel distance, the C values should be multiplied by 1.26. Similarly, it has a maximum dynamic load capacity (Cmax) that also varies based on travel distance—multiplied by 1.26 when based on 50 km. The ELINE BALL BUSHING KBC-30-DD-RT-G weighs approximately 0.18 kg and comes with an integrated wiper seal option for additional protection against contaminants while maintaining low frictional drag under no radial load conditions. It represents an efficient solution for various linear motion requirements across multiple applications without compromising performance or longevity.
