There are variations in depth and width due to the power being transmitted location and space available for the key etc. The parallel tolerance is tighter than symmetry. This is an intuitive concept to grasp- a clearance fit specifies a fit where there will always be a gap in the joint between the mating shaft and hole. British ISO Metric Screw Threads Designations. Slide Fit Key / Key slot. A radial style dimension appears and is attached to the path. 1. Each level of play has different specifications for the size and shape of the key: in American leagues, where the basketball court is measured in US units, the shape is rectangular, while in FIBA-sanctioned events, which use the metric system, the shape was trapezoidal before being changed to a rectangle as well. The key is then tightly fitted between the keyway and the keyseat, hence the mechanism is called a keyed joint. The hub keyway is dimensioned by its width and depth on the shaft – keyway sides. 3. . Unless you have a clearly defined and specific need for symmetry you can get the same control over the keyway using tolerance of position. The parallel tolerance is tighter than symmetry.
