The Bosch Rexroth RADIAL LINEAR BUSH KBR-30 (R067803000) is a high-precision linear bushing designed to move very heavy loads with exceptional smoothness and rigidity. This radial linear bushing features a shaft diameter of 30 mm and is engineered without seals, providing a high load rating due to its radial ball redirection, which allows for multiple rows of balls. It is particularly suitable for applications where other linear guides may experience warping due to imprecise substructures. The KBR-30 offers degrees of freedom in the circumferential direction and is characterized by its extra smooth running performance. It can be supplied fully sealed or without wiper seals, with separate wiper seals being an optional addition. The product is relubricatable, ensuring long-term maintenance possibilities, and includes a hardened and machined steel sleeve along with a ball retainer made of reinforced polyamide (PA) for durability. Equipped with balls made from rolling bearing steel and two retaining rings, the KBR-30 ensures reduced friction force and coefficient, contributing to its efficiency in operation. The dynamic load capacity is indicated for the main direction of loading, while the static load rating provides reliability under stationary forces. The product's design allows it to withstand a maximum acceleration and operate within a specified range of ambient temperatures. It has been crafted with precision tolerances for outer diameter D and shaft radial clearances (hbore K and hbore JS), which are crucial for optimal performance and lifespan. With its weight at 0.4 kg, the RADIAL LINEAR BUSH KBR-30 is also notable for its capability to handle maximum permissible linear speeds, ensuring it meets various application demands. Its robust construction makes it an ideal choice for heavy-duty guiding tasks where high rigidity and reliability are paramount.
