The Bosch Rexroth FLANGE LIN.BUSHING KBMF-16-DD-NR (R074021630) is a high-quality linear bushing designed for use in demanding environments where resistance to rust and heavy contamination is crucial. This robust all-metal flange linear bushing features a rugged design with a steel ball retainer, ideal for applications in woodworking, foundries, cement plants, and other harsh settings. It is also suitable for use in the medical, chemistry, and food industries due to its stainless steel construction. The KBMF-16-DD-NR model boasts an integrated wiper seal system that includes two seals to prevent dirt ingress and ensure smooth operation without jamming. The outer sleeve is hardened and machined from stainless steel, ensuring durability and long-term performance. The ball retainer and balls are also made of high-grade stainless steel, providing excellent resistance to wear and corrosion. This flange linear bushing has been designed with many pockets acting as lubricant reservoirs which facilitate extended lubrication intervals or even allow for lubrication-free operation under certain conditions. Its dynamic load capacities are based on a total travel distance of 100 km but can be adjusted for travel distances of 50 km by applying a multiplication factor to the values provided. With a permissible ambient temperature range from -20°C to +80°C (unsealed versions can handle higher temperatures with reduced load capacity), this product is versatile enough to operate effectively in various temperature conditions. The KBMF-16-DD-NR has an outer diameter of D1 size V1, with multiple rows of balls providing smooth motion. It comes with a specified breakaway force and maximum permissible linear speed vmax of 5 m/s, ensuring reliable performance in dynamic applications. Overall, the Bosch Rexroth FLANGE LIN.BUSHING KBMF-16-DD-NR (R074021630) offers a reliable solution for linear motion requirements in environments that demand high durability and resistance to contaminants.

Impact of load direction on load rating of closed Linear Bushings
The listed load ratings should be chosen depending on installation in minimum or maximum position and should be based on the calculations. If the load direction is clearly defined and the Linear Bushings can be installed in maximum position, the load ratings Cmax. (dynamic load rating) and C0 max (static load rating) can be used. If aligned installation is not possible or the load direction is not defined, the minimum load ratings must be used.
Definition of dynamic load ratings
Installation dimensions/interchangeability
Standard Linear Bushings have the same installation dimensions as super Linear Bushings. They are interchangeable, differ however in terms of securing, radial clearance, load ratings and lubrication.
Sealing
Standard Linear Bushings come with a wiper seal with shaft diameters of 5 and higher. Open standard Linear Bushings with shaft diameters 20 to 80 can also come fully sealed (with longitudinal seal; increased friction).
