12.5.2 Dimensions of the EG rails
The EG rails are used for both the EG and QE blocks.
EGR_R
EGR_U
Note:
1. The tolerance for E is +0.5 to –1 mm for standard rails and 0 to –0.3 mm for joint connections.
2. If the E
1/2
dimensions are not indicated, the maximum possible amount of fixing holes will be determined with regard to the E
1/2
min.
3. The rails are shortened to the required length. If the E
1/2
dimensions are not indicated, these will be carried out symmetrically.
