The Bosch Rexroth SUPER LINEAR BUSH (R073012040) is a high-precision linear bushing designed to facilitate the movement of heavy loads with maximum precision. This closed-type linear bushing features a shaft diameter 'd' and comes with one seal for enhanced protection against contaminants. It is equipped with hardened steel load-bearing plates that have precisely machined ball guide grooves, as well as a machined steel load-bearing plate back, which together ensure superior accuracy and rigidity. The SUPER SH series of this bushing includes an increased number of running tracks, which contributes to its exceptional dynamic load rating and stiffness. This design effectively compensates for shaft deflection and misalignment, ensuring smooth operation even under challenging conditions. The bushing is capable of high travel speeds, reaching up to 'ms', and can handle maximum accelerations without compromise. For maintenance purposes, the SUPER LINEAR BUSH may come with optional integrated double-lipped wiper seals. The POM ball retainer within the bushing holds balls made of rolling bearing steel, which are secured by two metal holding rings. The structure allows for multiple rows of balls within the series Super SH configuration. In terms of performance characteristics, this linear bushing offers a static load rating (C0) and dynamic load capacity (C), indicating its ability to withstand both stationary and moving loads effectively. Its friction coefficient ranges from a minimum value to a maximum value of 0.3 under certain conditions, demonstrating its efficiency in reducing resistance during operation. The product has been designed to operate within an ambient temperature range from -20°C to +80°C, ensuring reliability across various environmental conditions. The outer diameter (D) is specified along with other critical dimensions that contribute to its compatibility with corresponding equipment or machinery. With a weight of 0.2kg and specific radial clearance specifications for shaft-to-bore fitment, the Bosch Rexroth SUPER LINEAR BUSH ensures precise alignment and smooth motion transfer in diverse applications requiring linear guidance systems.
