Outer sleeve for high-precision linear motion ball bushing providing structural housing and guidance.
The outer sleeve is a cylindrical housing component in a high-precision linear motion ball bushing assembly that contains and supports the ball recirculation system, maintains alignment with the shaft, and provides mounting interfaces for machine structures. It ensures precise linear movement by maintaining consistent internal geometry and surface finish for ball tracking.

The outer sleeve provides the structural housing that contains the ball recirculation system, maintains precise alignment with the shaft, and offers mounting interfaces for integration into machine structures while ensuring consistent linear motion.
Material selection determines wear resistance, load capacity, and corrosion resistance. High-carbon chromium steel offers optimal hardness and durability for heavy loads, while stainless steel provides corrosion resistance for harsh environments, and aluminum reduces weight in high-speed applications.
Critical tolerances include inner diameter (H6/H7 for proper shaft fit), outer diameter (h6 for housing fit), straightness (0.01 mm/100 mm max), and surface roughness (Ra 0.4 μm max) to ensure smooth ball movement and minimal vibration.
