Superior Stability: FL-A Series Flange Single Taper Locking Assemblies

The FL-A Series represents a high-performance keyless locking solution designed for high-load industrial transmissions. By utilizing a single-taper flange structure, this locking assembly ensures a secure, friction-based connection between the shaft and hub. Manufactured from forged 45# steel and precision-machined to H7 tolerances, it provides exceptional concentricity and durability for critical motion control systems.

Core Product Advantages

• High-Strength Forged 45# Steel: The entire unit is made from quenched and tempered 45# steel forgings, ensuring a long service life and resistance to deformation under high torque.

• Zero Axial Displacement: Our unique design ensures that the coupling unit does not shift axially during bolt tightening, maintaining perfect alignment of your drive components.

• H7 Precision Self-Centering: The inner ring notch design allows the lining sleeve to press tightly against the hub bore, actively controlling runout and achieving superior centering effects.

• High-Grade Hardware: Equipped with 12.9-grade high-strength locking bolts to ensure maximum clamping force and vibration resistance.

• Simplified Installation & Removal: No hammering or complex tools required. Simply tighten or loosen the bolts to secure or release the connection, significantly reducing maintenance downtime.

• Stackable Design: For applications with extreme loads, multiple FL-A units can be used in series to increase the transmission capacity.
