The Bosch Rexroth SUPER LINEAR BUSH KBB-O-50-D (R067315040) is a high-performance linear bushing designed for smooth travel and a long service life. This low-cost linear bushing meets high requirements with its steel bearing plates, which have machined ball guide grooves and optimized ball lead-in chamfers. The KBB-O-50-D lacks a self-alignment feature, which means it transfers lower tipping forces along the axial direction and is ideal for applications requiring precise linear guidance without the need for self-correction. This open linear bushing is compatible with fully supported shafts and is an excellent choice for situations where other linear guides might warp due to less precise substructures. It boasts a high travel speed of up to 5 meters per second, although this maximum speed can lead to increased wear on plastic parts. The integrated wiper seal helps maintain cleanliness within the system, although additional frictional drags are generated when radial loads are not present. The dynamic load capacity C of the KBB-O-50-D indicates that it can handle significant loading in its main direction, while its static load rating C underscores its ability to withstand stationary forces. The friction coefficient of this model ranges from 0.01 to 0.02 under lubrication with oil and varies based on load conditions. Constructed with a ball retainer and outer sleeve made of PA or POM, and balls crafted from rolling bearing steel, this product requires no initial lubrication upon installation. Its permissible ambient temperature ranges from -20°C to 80°C, making it suitable for various operating environments. The SUPER LINEAR BUSH KBB-O-50-D has an outer diameter E size of 80 mm and weighs approximately 1 kg. It offers different radial clearances (shaft bore) options such as K, H, and M classes to accommodate various precision requirements.
