Mark/B-LOC: The most challenging applications are those in which components are subjected to continuous shock, vibration, or reversing loads, in these cases, keyless locking devices generate sufficient preload to ensure backlash-free connection.Jeff/KTR: Applications that include large reversing loads provide the greatest challenges.Vic/Rimtec: If the goal is accurate positioning, high-duty cycle, reversing loads are the most difficult, especially if they require high acceleration and deceleration.Jeff/Tollok: The most challenging applications almost always involve extremely high torques or heavy shock loads. Operational environment and other external influences can also be challenging.PitfallsWhat are the most common pitfalls and how can they be prevented?Jeff/Tollok: Selecting the wrong type of locking assembly is a big issue. Erroneous sizing calculations and improper installation and mounting are chicagoneumaticairtooloil other pitfalls. My advice is to carefully review your application parameters with your locking assembly supplier.

Warren/Fenner: Failure to take into consideration the compression forces and outward forces generated when using locking devices. The mounted component must have sufficient wall thickness to withstand the outward forces or it will burst. Likewise when mounting on hollow-shaft or tubular applications. Inadequate wall thickness results in the hollow shaft or tube being compressed and distorted. Many manufacturers publish a formula or table that lets designers calculate the required wall thickness.Vic/Rimtec: Having too much clearance between the shaft and hub is often a problem; you can''t clamp enough to transmit rated torque. Overtightening the screws is also common, causing tapers to lock when they''re supposed to disassemble. This is where locking devices with push-off screws come in handy.
