Superior Strength: AL-L Series Double Taper Locking Assemblies

The AL-L Series is a high-strength, double-tapered keyless locking device designed for heavy-duty power transmission. Engineered to replace traditional keyed joints, it provides a high-torque, interference-fit connection between shafts and hubs without stress concentration, ensuring maximum reliability for mission-critical machinery.

Core Product Advantages

• Premium 45# Forged Steel: Entirely tempered and forged for superior wear resistance, hardness, and toughness, ensuring long-term structural integrity under heavy loads.

• 12.9 Grade High-Strength Bolts: Equipped with precision-ground, burr-free fasteners that ensure secure tightening and prevent loosening during high-vibration operation.

• Self-Centering & Precise Positioning: Features excellent concentricity and allows for arbitrary axial and circumferential adjustment of the hub relative to the shaft.

• High Load Capacity with No Stress Concentration: The uniform pressure distribution eliminates the localized stress common in keyway designs, significantly increasing the fatigue life of the shaft.

• Simplified Installation & Reusability: No hammering required—simply tighten the bolts for a secure fit. The unit is fully reusable and can be easily disassembled for maintenance.

• Safety Overload Protection: Acts as a safety mechanism by slipping during extreme overload, protecting expensive drive components from damage.
