Key a Machined at the same set-up as d 4 . b Polished. c Lead-in chamfer for sealing. d Sliding sleeve, only needed for mounting the transfer unit into a coupling of size 32 to 50. This sliding sleeve is replacing the lead-in chamfer inside the coupling due to limited unclamping surface. Figure 1 — Transfer unit for polygonal taper interfaces — Nominal sizes 32 to 80 4.2 Transfer unit for polygonal taper interface, nominal size 100 The transfer unit for polygonal taper interfaces for nominal size 100 shall be carried out according to Figure 2 and Table 1.
4.3 Design 4.3.1 General The transfer unit shall seal a pressure of at least 70 bar 1) and be neutral centred and allow an angular movement of ±1° with a small displacement force. Transfer unit for polygonal taper interface assembly model is described in Annex A. 4.3.2 Hardness The supply tube shall be surface hardened, hardness at least 56 HRC (Rockwell hardness C). 4.4 Designation A transfer unit in accordance with this document shall be designated by: a) “Transfer unit”; b) reference to this document, i.e. ISO 22402-2; c) nominal size of the polygon-shank in mm (e.g. 50). EXAMPLE Designation of a transfer unit for a polygon-shank with the nominal size 50 mm: Transfer unit ISO 22402-2 — 50
