The dimensions of ejector sleeves with cylindrical head shall be in accordance with the indications of Figure 1 and Table 1.5 Material and hardness Ejector sleeves with cylindrical head shall be made of hot worked steel or alloyed cold worked steel.The hardness of the shaft and head, respectively, are given in Table 2.6 Designation Ejector sleeves with cylindrical head according to this document shall be designated by the following:a) “Ejector sleeve with cylindrical head”;b) a reference to this document (i.e. ISO 8405);c] the diameter, D1, in millimetres;d) the length, L, in millimetres;e) the material.EXAMPLE An ejector sleeve with cylindrical head with diameter D1 = 2 mm, length L = 75 mm, and made of hot worked steel is designated as follows:Ejector sleeve with cylindrical head Iso 8405.2.75 – Hot worked steelKey x standardized dimensions NOTE Tolerance classes and limit deviations are defined in IS0 286-2. For repair, the following diameters for D1 are recommended: 2,2; 2,7; 3,2: 3.7. 4,2; 5,2: 6,2: 8.2; 10.2: 12.5.For shaft diameters, D2, larger than those given in this table, up to 32 mm, the ratio of head height and diameter shall be the same as for ejector pins given in IS0 6751.BS ISO 8405 pdf download.
