The Bosch Rexroth COMPACT LIN. BUSH. KBC-20-DD (R065822040) is a high-quality compact linear bushing designed to provide smooth and precise linear motion in various applications. This model features a shaft diameter of 20 mm and incorporates two seals, ensuring that contaminants are kept out and maintenance requirements are minimized. With standard radial clearance and a non-lubricated design, it offers a low-cost solution for general requirements while maintaining high dynamic load ratings and long service life. The KBC-20-DD is constructed with hardened segmental load-bearing plates which enhance ball conformity in the running track, allowing for high travel speeds of up to m/s. Its compact size ensures that it can be integrated into tight spaces without sacrificing performance. The bushing also includes many pockets that act as lubricant reservoirs, potentially extending lubrication intervals or even achieving lubrication for life. These pockets also serve to collect any dirt ingress, preventing jamming of the bushing. Installation is straightforward with the COMPACT LIN. BUSH., as it simply needs to be pressed onto the shaft; no additional retention is necessary. The integrated metal retainer is approximately 0.1 mm larger than the outer diameter of the shaft (ranging from 3 to 50 mm), which guarantees a secure fit within the housing bore. The product's specifications include an outer diameter (D) of mm, length of linear bushing L, and weight of 0.2 kg. It can operate within an ambient temperature range of -30°C to +80°C without compromising function or performance. The friction coefficient ranges from µ = 0.01 to µmax = 0.25, with friction force FR noted under specific conditions in the footnote. Designed for use with linear guides type Linear Bushing and Shaft in a closed format, this Bosch Rexroth linear bushing represents an efficient solution for facilitating precise linear movement across various applications without necessitating frequent maintenance or complex installation processes.
