Superior Solution for Shaft Connections in Large Bore Applications
Traditional large cast iron couplings, commonly utilized to connect shafts in various heavy-duty applications such as lumber, steel, rail, recycling, and paper industries, are typically manufactured from iron and are known for their substantial weight.
Conventional large cast iron couplings feature a bulky design, necessitating extra space to accommodate their oversized outer diameter. The sheer size of these antiquated couplings places undue stress on the shaft and increases the risk of damaging both the shaft and its associated components. Likewise, to achieve the necessary torque for these applications, cast iron couplings rely on a keyway, leading to issues such as wallowing, backlash, fretting corrosion, and fatigue failure, all commonly associated with keyways.
Keyless Locking Devices Provide Solutions for Mining Industry
Whether your operation is surface, conventional or longwall mining, your machinery is constantly subjected to some of the harshest environments and torturous loads for which an engineer can design. To compensate, for many application designers forgo traditional keys and keyways which are subject to failure and rely upon splice and interference fits to mount critical components on rotating shafts.

Optimal Solution for Mining Belt Conveyor Systems
Climax Keyless Locking Devices provide advantages over keyed connections. Mining OEMs incorporate keyless connections in equipment design.
Drum pulleys, especially head or tail pulleys, using traditional keyed connections introduce several compromises. Whenever a shaft is keyed, it must be oversized to account for the loss of effective cross section. This adds weight and cost not only to the shaft, but to every component on the shaft. Once assembled, keyways are susceptible to fretting, corrosion, and allow backlash. QD, XT, or taper-lock bushings do not transmit reversing bending moments and are susceptible to shaft fatigue failure originating at the keyways. Climax KLDs eliminate the need for keyways reducing downtime and loss of profit while allowing the use of smaller shafting and components. KLDs provide a longer life for both mine duty and engineered class conveyor pulleys.

Mining Shovels & Excavators Benefit From the Use of Climax KLDs
Climax Keyless Locking Devices offer an alternative for clumsy clevis pin retention and brake rotors in excavators and dragline shovels.
One of the most commonly used pieces of heavy mining equipment is excavators or power shovels. Every major construction project requires their use. Tasks such as removing large objects, digging trenches, site grading, hauling, demolition, mining, snow removal, would be practically impossible without this machinery.
Construction machinery is constantly subjected to the harshest environments and toughest loads for which an engineer can design. Maintenance is an important factor in keeping costs down and ensuring that construction site progress stays on schedule. Moving parts are expected to wear out over time especially where (more…)
Mechanical Integrity Without Machining: KLD Solutions for Crusher Shaft Interfaces
Mining-grade crushing equipment can achieve greater mechanical integrity and simplified maintenance using Climax Keyless Locking Devices, which outperform conventional keyed connections.
KLD Ensures Integrity Without Machining
Jaw crushers widely used in the mining industry, often rely on costly press or sweat fits, or traditional keyed connections. However, these approaches often come with several drawbacks. Keyed shafts must be oversized to compensate for reduced effective cross-section, increasing weight and cost – not just for the shaft itself, but for every component mounted on it. Additionally, keyways are prone to fretting corrosion, backlash, and are incapable of transmitting bending moments or axial loads.
Impact crushers incorporating interference-fit rotor-to-shaft connections require precision machining, specialized fixturing, high-capacity hydraulic presses, and substantial labor investment during assembly. Climax heavy-duty locking assemblies, such as the C405-Series, achieve the same mechanical integrity of interference fits while significantly reducing manufacturing complexity and cost, with a simplified machining investment. Additionally, these locking assemblies provide a robust solution for mounting drive sheaves, effectively eliminating the drawbacks associated with keyed connections – including fretting, backlash, and limited load transmission, as well as belt misalignment issues inherent to QD or XT bushings.
