Warren/Fenner: Failure to take into consideration the compression Aor 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 Tool wall thickness results in the hollow shaft or tube being compressed and distorted. Screwdrivers 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.

Component interactionsHow do locking device choices affect other areas of the machine or system?Andrew/Whittet-Higgins: The precision and life expectancy of a bearing, power transmission, or modern assembly is only as good as the precision of the Aor individual components and the care in which they are put together.Blair/Ruland: It''s important to look at where and how the Tool locking device is being used and whether adjustments may cause problems. Locking devices in general are not easy to remove and replace. Because of this, it may be advantageous to have necessary adjustments done from another section of the machine.Doug/Zero-Max: When using keyless locking devices, there are fewer application problems because there is no keyway failure or fatigue. Connections without keyways also have smaller shaft diameters, translating into shaft material cost savings. The single screw type can be tightened and repositioned many times without component wear or machine downtime.
