The Bosch Rexroth SUPER LINEAR BUSH (R067002000) is a high-quality linear motion component designed for smooth and precise linear movement. This model, part of the KBA-20 series, features a closed design without seals, which makes it a cost-effective solution for applications requiring high performance. The SUPER LINEAR BUSH is equipped with steel bearing plates that have machined ball guide grooves and optimized ball lead-in chamfers to ensure exceptionally smooth travel and an extended service life. The KBA-20 model compensates for shaft deflection and misalignment up to specified tolerances, maintaining high travel speeds of up to 5 meters per second. It does not require initial lubrication, which simplifies installation and maintenance. The linear bushing's ball retainer and outer sleeve are constructed from either PA (Polyamide) or POM (Polyoxymethylene), while the balls themselves are made from rolling bearing steel, providing robust performance. This linear bushing can handle a dynamic load capacity up to the maximum Cmax value provided in its specifications with an acceleration amax also specified. It operates efficiently within a permissible ambient temperature range of -30°C to +80°C. The outer diameter is precisely defined as per the product specifications, ensuring compatibility with various shaft sizes. The friction coefficient of this unsealed linear bushing varies between minimum and maximum values when lubricated with oil, with the lowest friction occurring under heavy loads. However, even under low loads, the friction coefficient can exceed the minimum value specified. The breakaway force is also detailed in the specifications, giving insight into the initial force required to start motion. With a weight of 0.2 kg and specific radial clearance values for different fits (shaft-bore K, H, M), this SUPER LINEAR BUSH offers flexibility for various industrial applications. It's suitable wherever low-cost yet high-requirement linear motion is needed, such as in automation equipment or precision machinery.
