BK 13/50x80 Locking Assembly for Shaft-Hub Connections

Reliable Shaft Locking Solution for Industrial Power Transmission

BK 13/50x80 Locking Assembly is a precision self-centering shaft locking device designed to create a strong friction-based connection between a shaft and mounted transmission components. This mechanical locking element eliminates the need for keyways, splines, pins or shrink fits while providing excellent torque transmission and concentricity. The BK 13 series is widely used in industrial drive systems, conveyors, gearboxes, electric motors and production machinery where accurate shaft-to-hub mounting is essential.

Application in Industrial Systems

The BK 13/50x80 locking assembly is commonly installed in industrial power transmission equipment requiring reliable shaft-hub connections. Typical applications include:

• Industrial gearboxes
• Drive systems
• Conveyor systems
• Pulley mounting
• Sprocket mounting
• Coupling assemblies
• Packaging machinery
• Agricultural machinery
• Material handling equipment
• OEM machine construction

The self-centering design ensures precise alignment between the shaft and hub, improving operational stability and reducing vibration.

Construction and Design

The BK 13 locking assembly utilizes a self-centering tapered locking mechanism that generates uniform radial pressure between the shaft and hub. This design allows high torque transmission while maintaining accurate concentricity.

Unlike traditional keyed shaft connections, the locking assembly distributes forces evenly across the entire contact surface. This minimizes stress concentrations and improves component life.

Key design features include:

• Self-centering construction
• Mechanical wedge locking system
• High concentricity
• Compact overall length
• Easy installation and removal
• Maintenance-friendly design
• High clamping force
• Keyless shaft connection

Industrial entities naturally associated with this product include locking assembly, locking device, shaft locking element, shaft-hub connection, clamping element, keyless locking device, power transmission component, drive coupling, industrial coupling and mechanical transmission system.

Material Properties

BK 13/50x80 locking assemblies are manufactured from high-strength steel designed for demanding industrial applications. The material provides excellent resistance to mechanical loads and long-term operational reliability.

Benefits of the steel construction include:

• High tensile strength
• Excellent fatigue resistance
• Reliable torque transmission
• Dimensional stability
• Long service life
• Resistance to industrial operating conditions
