The letters describe broad construction, not a universal set of dimensions, so bore capacity and length through bore still need to be checked on the selected drawing.<\/p>\n<\/details>\n<details style=\"background:var(--color-neutral);border-left:4px solid var(--color-accent);border-radius:8px;padding:14px 16px;margin:0 0 10px;\">\n<summary style=\"color:var(--color-brand);font-weight:700;cursor:pointer;\">Which sprocket hub style is best for a keyed shaft?<\/summary>\n<p >A Type B or Type C design usually provides more hub length for a finished bore and keyway than a plate-only Type A, but the right choice depends on shaft diameter, torque transfer, axial space, and the manufacturer&#x27;s maximum bore.<\/p>\n<\/details>\n<details style=\"background:var(--color-neutral);border-left:4px solid var(--color-accent);border-radius:8px;padding:14px 16px;margin:0 0 10px;\">\n<summary style=\"color:var(--color-brand);font-weight:700;cursor:pointer;\">Can a Type A sprocket be bored and keyed directly?<\/summary>\n<p >Some plate sprockets can be machined or attached to a separate hub, but a thin plate does not automatically provide enough bore length or wall section for a keyed shaft.
