Specification

SEODescription

The Φ70-76 expansion sleeve is a robust mechanical fitting designed for industrial applications requiring secure shaft-to-hub connections. Featuring an Ordinary expansion 8x50 configuration, this component integrates eight 50mm-diameter expansion elements within a Φ70-76mm housing, enabling direct compatibility with standard industrial gearboxes and rotating equipment. Its 8x50 mechanical fitting design ensures uniform radial pressure distribution, supporting torque transmission up to 980 N·m. Operating within -30°C to +120°C temperature ranges, it suits heavy machinery, conveyor systems, and power transmission applications. Key advantages include tool-free installation, corrosion-resistant steel construction, and tolerance compensation for minor shaft imperfections. Limitations include strict adherence to specified shaft diameter tolerances (ISO h9) and reduced effectiveness in high-vibration environments without supplementary locking mechanisms. The sleeve requires no electrical interfaces, functioning purely through mechanical expansion principles.
