shear stress key τ = F s / (L搓) MPa. bearing pressure p = F s / (h/2 微) MPa. Nominal torsional stress τ = T/ ( π/16搞 k3 ), d k =d-t 1. MPa. Key dimensions: Parallel keys are most commonly used. The key and key seat cross section are ISO standardized. The key length should be less than about 1.5 times the shaft diameter to ensure a good

ISO 286-2: - Geometrical product specifications (GPS) -- ISO code system for tolerances on linear sizes (Part 1: Basis of tolerances, deviations and fits & Part 2: Tables of standard tolerance classes and limit deviations for holes and shafts) ISO 3912:1977 - Woodruff keys and keyways; ISO 3117:1977 - Tangential keys and keyways

the following tolerances for maximum lead (due to angular displacement of keyseat centerline from centerline of shaft or bore and measured at right angles to the shaft or bore centerline) of keyseats in shaft and bore are specified: 0.002 inch for keyseat length up to and including 4 inches; 0.0005 inch per inch of length for keyseat lengths

Calculate fits and tolerances for shafts and holes here. Based on standard tolerances and limit deviations in accordance with ISO 286.

The dimensions of a fit are calculated using the tolerances according to ISO 286 ( ). In addition to the deviations of shaft and hub, the span, 

1, the Metric key size is W x T. The keyway dimensions are also different from the English system. Metric keyways are dimensioned by width and depth as measured from the radius of the shaft to the center of the keyway. See dimensions W and h in Figure 1. Unless otherwise specified, the shaft keyway is assumed to be standard. Also, T1 and T2 are not

07/05 · In the following section you will find information on British standard keyway and bore sizes. John Kings will generally bore all wheels to a H7 tolerance unless specified by the customer. All wheels will come with grub screw fixings over keyways and at 90 degrees as standard. The standard positioning for all keyways will be in line with a tooth. []
