specification According to EN 2311 Design recommendation Bushes defined by this standard are intended to be installed by interference fit methods (see Figure 2) Therefore, the loads given in Table can only be ensured if the following mounting is applied Key Shaft diameter d f6 Bush Housing diameter D H6 Figure — Design recommendation Hardness of the shaft: 50 HRC Surface roughness of the shaft: according to Figure The reduction in nominal diameter d (see Figure 1), due to interference fit of the bush in the housing, has been taken into account when selecting tolerances for the shaft: f6 (clearance fit) When applied in actual usage, the coefficient of friction under load could be different from that defined in EN 2311 since it depends on the following shaft definitions: Materials, hardness, surface finish, surface treatment and installation conditions 14 BS EN 4534-2:2016 EN 4534-2:2016 (E) Annex A (informative) Standard evolution form The main changes with respect to the
