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 air and tooos 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 for a formula or table that lets designers calculate the required wall thickness.Vic/Rimtec: sell Having too much clearance between air the shaft and hub is often a problem; you can''t tooos 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.

Jim/Stafford: for Early design involvement on the part of the manufacturer is the best way to make sure the resulting component will be reliable and effective.Jeff/Tollok: sell Carefully review your application requirements. Shaft material, hub material, transmittable torques, and bending moments can influence your selection of the proper locking assembly.Intelligent designWhat can DESIGNERS do when selecting and applying locking devices to improve productivity?Jeff/KTR: Obtaining comprehensive technical information will improve selection and performance. Find a manufacturer that maintains the quality of materials, dimensions, and surface finishes.Jeff/Tollok: Too often air not enough questions are asked, and selections are made based on previous designs. Don''t use the same locking assembly simply because it was used elsewhere on the same machine or on a previous machine design. Involve your supplier and use their experience to get recommendations.
