The Bosch Rexroth COMPACT LIN. BUSH. KBC-20-D-NR (R065812030) is a compact linear bushing designed for general requirements, offering both small outer dimensions and a highly compact construction. This model features a standard radial clearance and is rust-resistant, catering to applications where these properties are essential. It is not pre-greased, reflecting its low-maintenance design and suitability for high-speed operations with a maximum travel speed of 5 m/s. This linear bushing boasts high dynamic load ratings and promises an extended service life due to its hardened segmental load-bearing plates with ball conformity in the running track. It can accommodate shaft diameters from 3 to 50 mm, ensuring a secure fit in the housing bore thanks to integrated metal retainer rings that are approximately 1 mm larger than the outer diameter of the shaft. The KBC-20-D-NR is particularly relevant for use in environments such as medical, chemistry, and food industries because it is constructed from stainless steel. The design includes pockets that act as lubricant reservoirs which can prolong lubrication intervals or even enable lubrication for life, while also collecting dirt to prevent jamming. The product has an integrated wiper seal which affects the friction force—when factoring in one seal, this value should be multiplied by 1.25. For technical specifications, the product offers a maximum dynamic load capacity (Cmax) and minimum static load capacity (Cmin), with specific coefficients provided based on different total travel distances. The permissible ambient temperature range for operation spans from -30°C up to +80°C, ensuring reliability across various working conditions. Additionally, the linear bushing has a closed format and falls under the product group ID of Linear Bushings. Lastly, it weighs approximately 0.04 kg and has been designed with ease of installation in mind; no additional securing is needed beyond pressing it into place. This model ensures functionality and durability for various linear motion applications without necessitating frequent maintenance or complex installation processes.
