Bosch Rexroth R067303000 Super Linear Bushing

Bosch Rexroth R067303000 Super Linear Bushing, model KBB-O-30, is a precision linear motion bearing designed to guide a 30 mm shaft with smooth, repeatable travel and high stiffness in demanding environments. The bushing uses steel bearing plates with machined ball guide grooves and optimized ball lead-in chamfers to ensure uniform ball circulation and a long service life under challenging operating conditions. It is a closed, non-self-aligning design, meaning it does not compensate shaft deflection and transfers tipping forces along the axial direction, which makes it well-suited for fully supported shafts and rigid substructures where precision must be maintained. Common applications include automation equipment, machine tools, and CNC assemblies that require reliable, low-friction guidance on a fixed shaft, enabling accurate positioning and repeatable motion over extended service intervals. The KBB-O-30 designation confirms a 30 mm shaft interface, and the Super Linear Bushing approach provides stable guidance without the complexity of larger rail-and-block systems, delivering a compact option when precise linear travel and a tight form factor are priorities, while favoring environments where shaft straightness is well-controlled.
