Precision-machined cylindrical bore and raceway surfaces in linear guides and bearing housings that enable smooth, low-friction linear motion.
The bore/raceway is a critical precision-engineered component within linear guides and bearing housings, consisting of precisely machined cylindrical surfaces that serve as the contact interface for rolling elements (balls or rollers). These surfaces are designed with specific geometric tolerances, surface finishes, and hardness characteristics to minimize friction, distribute loads evenly, and maintain alignment during linear motion. The bore provides the mounting surface for the shaft or rail, while the raceway guides the rolling elements along a controlled path, ensuring consistent motion accuracy and load capacity.

The bore is the cylindrical mounting surface for the shaft or rail, ensuring proper fit and alignment. The raceway is the precisely ground track where rolling elements (balls/rollers) travel, controlling motion path and load distribution.
Raceway geometry (e.g., Gothic arch or circular arc) determines contact angle, load distribution, and stiffness. Optimal geometry reduces stress concentration, minimizes friction, and enhances accuracy and lifespan.
Regular cleaning to remove contaminants, lubrication with appropriate greases (e.g., lithium-based), and inspection for wear, pitting, or corrosion. Avoid abrasive cleaners and ensure proper alignment during installation.
