The Bosch Rexroth FLANGE LIN.BUSHING KBMM-20-DD (R074252000) is a robust and high-quality flange linear bushing designed for demanding applications requiring a central flanged configuration. This standard metal bushing features a hardened and ground outer sleeve, providing durability and precision. Its POM ball retainer ensures smooth ball movement, while the balls themselves are crafted from rolling bearing steel for reliable operation. With a shaft diameter of 20mm, this linear bushing is equipped with two integrated wiper seals to protect against contaminants, making it suitable for harsh environments such as woodworking shops, foundries, and cement plants. The wiper seals not only keep out dirt but also help maintain lubrication by containing multiple pockets that act as reservoirs. This design extends lubrication intervals or potentially allows for lubrication-free operation. The KBMM-20-DD can handle dynamic loads efficiently due to its rugged all-metal design with steel ball retainer that can withstand heavy contamination without jamming. The product's maximum dynamic load capacity and static load capacities are calculated based on a total travel of 100 km; however, these values can be adjusted if the travel is reduced to 50 km by multiplying by a factor provided in the specifications. This linear bushing operates effectively within a permissible ambient temperature range. It's important to note that unsealed linear bushings like this one may be used at higher temperatures with appropriate considerations for load capacity reduction. Overall, the Bosch Rexroth FLANGE LIN.BUSHING KBMM-20-DD offers reliability and performance for linear motion applications where environmental conditions are challenging and precision is critical. Its construction ensures long service life with minimal maintenance requirements, making it an excellent choice for various industrial applications.
