chmotion BC4XLSS Concentric Bushing with Guide Wheels
Standard Head, 303 Stainless Steel Bushing for Inch-System Linear Guides

Key Advantages

• 303 Stainless Steel Construction: Superior corrosion resistance for harsh environments like food processing, medical, and washdown applications.
• Ready-to-Install Kit: Delivered together with compatible W-series guide wheels, simplifying procurement and assembly.
• Precision Concentric Design: Stationary (non-adjustable) bushing ensures consistent, repeatable alignment and smooth rolling motion.
• Inch-System Standard: 4XL size with key dimensions in inches, designed for compatibility with a wide range of imperial linear guide systems.
• Detailed Tolerances: Critical dimensions like head thickness (THH: ±0.025mm) and mounting hole (TID: +0.051/-0.025mm) are tightly controlled for reliable performance.
