H 517 Precision Adapter Sleeve | Secure Tapered Bore Mounting for 80mm Shafts | SKF Equivalent
The H 517 Adapter Sleeve is a critical high-precision component engineered for reliably mounting self-aligning bearings (such as spherical roller bearings or CARB bearings) with a tapered bore onto cylindrical shafts. Constructed from high-strength, precision-machined steel, the H 517 ensures even distribution of mounting forces, preventing localized stress on the bearing races. This sleeve is specifically designed to accommodate bearings with an 85 mm bore (tapered) when fitted to a nominal 80 mm shaft diameter. Its standardized 1:12 taper facilitates precise radial clearance adjustment, guaranteeing optimal performance and extended service life in demanding industrial environments.
Selecting the correct adapter sleeve is paramount for maximizing bearing operational reliability and minimizing costly unplanned downtime. The H 517 offers superior concentricity and security, providing a robust, non-positive friction lock that resists axial forces and vibration in heavy-duty applications like conveyor systems, crushers, and process machinery. Its design simplifies both initial installation and future dismounting, utilizing standard hydraulic or mechanical locking nut tools (e.g., KM 17). By ensuring proper fit and minimal runout, the H 517 drastically reduces the risk of premature bearing failure, maximizing asset utilization and providing a superior long-term ROI for maintenance operations.
