The Bosch Rexroth STD.LINEAR BUSHING KBM-E-30-DD (R061203010) is a robust and high-quality linear bushing designed for a wide range of motion applications. This standard linear bushing features an adjustable design with a shaft diameter of 30 mm and incorporates two seals to withstand harsh environments and heavy contamination. Its rugged all-metal construction includes a steel ball retainer, making it suitable for use in demanding conditions such as woodworking, foundries, and cement plants. The KBM-E-30-DD is engineered with many pockets that act as lubricant reservoirs, which can extend lubrication intervals or even allow for lubrication for life. These pockets also serve to collect dirt and debris, preventing the linear bushing from jamming. The lack of wiper seals and the presence of integrated steel retaining rings enable this linear bushing to function at higher temperatures when used with shaft diameters of 30 mm and above. The outer sleeve is hardened and ground for durability, while the steel ball retainer ensures smooth motion. For shaft diameters of 30 mm and higher, a plastic retainer made of PA is used. The balls are crafted from rolling bearing steel to maintain high precision in movement. The design allows for radial clearance adjustment, providing flexibility in application. With a series designation of Standard metal E, the KBM-E-30-DD has an outer diameter D of 45 mm. It has been designed to handle maximum dynamic load capacities with allowances for reductions at elevated temperatures or under vacuum conditions. Its permissible ambient temperature range is from -20°C to +80°C without wiper seals. This model has a weight of 0.21 kg and features a friction coefficient ranging from 0.01 to 0.25 under various load conditions. The dynamic load capacities are based on a total travel distance of 100 km but can be adjusted if based on different travel distances. In summary, the Bosch Rexroth STD.LINEAR BUSHING KBM-E-30-DD offers exceptional performance for linear motion applications requiring high durability, adjustability, and resistance to environmental contaminants and temperature extremes.
