The Bosch Rexroth COMPACT LIN. BUSH. KBC-20-DD-NR (R065822030) is a high-performance compact linear bushing designed for general requirements with a focus on small outer dimensions and highly compact construction. This particular model features a shaft diameter of 20 mm and comes with two seals, ensuring protection against contaminants while maintaining a normal radial clearance. Its corrosion-resistant version is not greased, which suits applications where lubrication maintenance is minimal or not possible. The KBC-20-DD-NR boasts a high dynamic load rating and an extended service life due to its hardened segmental load-bearing plates that ensure ball conformity in the running track. The use of stainless steel makes it suitable for demanding environments such as the medical, chemistry, and food industries. The linear bushing's design includes many pockets that act as lubricant reservoirs, potentially extending lubrication intervals or even allowing for lubrication for life. These pockets also serve to collect dirt that may enter the system to prevent jamming. Installation of this linear bushing is straightforward; it requires simply pressing onto the shaft with no additional retention needed, thanks to integrated metal retainer rings that are approximately 0.5 mm larger than the outer diameter of the shaft diameters ranging from 3 to 50 mm, ensuring a secure fit in the housing bore. The product has multiple rows of balls within its structure and can achieve high travel speeds up to n ms. It operates efficiently within a permissible ambient temperature range from -30°C up to +80°C. The COMPACT LIN. BUSH. KBC-20-DD-NR maintains low friction coefficients under various loads with a maximum dynamic load capacity (Cmax) and minimum dynamic load capacity (Cmin) based on total travel distances of 100 km and 50 km respectively. With its robust construction and versatile capabilities, this Bosch Rexroth linear bushing is an ideal solution for smooth linear motion in compact spaces across various industries requiring precise movement control and durability.
