Technical Knowledge
Technical Knowledge A size chart is most useful when it helps identify a real part, not when it is treated as a substitute for the full drawing. For EP taper-lock bushings, the…

Technical Knowledge
Technical Knowledge A bushing can have the correct outside taper and still be wrong for the shaft if the keyway standard is mismatched. That is why global replacement work needs more than…

Product Comparison
Product Comparison Material names matter because they describe how a bushing may respond to machining, clamping and shock, but they should not be treated as a shortcut for application design. A cast-iron…

Product Comparison
Product Comparison XT and QD bushings are both flanged, removable shaft connections, so they can look related in photographs. Their model systems and mating hubs are different, however, and that difference controls…

Product Comparison
Product Comparison “Split” and “solid” are often used loosely in maintenance conversations, but the practical issue is the complete shaft-to-hub system. A split taper bushing is designed around a specific split body…

Product Comparison
Product Comparison Taper Lock and QD bushings solve the same broad problem—mounting a rotating component on a shaft—but they are not two names for one interface. The mating hub geometry, flange arrangement…

Installation & Maintenance
Installation & Maintenance Taper bushings usually spend most of their service life out of sight inside a pulley, sheave or sprocket. That makes condition-based inspection more useful than a fixed calendar replacement…

Installation & Maintenance Tightening torque matters because it controls how the fasteners draw the tapered surfaces together. Too little clamp can leave movement in the connection; too much can overload threads, screws…

Installation & Maintenance Removal is not the reverse of installation in the sense of simply pulling harder. Taper-lock systems are designed with specific threaded positions that let the screws act as jacks…

Installation & Maintenance A taper lock bushing looks simple, but the connection only works as intended when the shaft, keyway, mating hub and fasteners are treated as one assembly. A clean taper…
