E The hardness of shaft end machined part (effective thread length + approx. 10mm) may be reduced due to the annealing effect of machining.
E If there are requirements for rust prevention, please give priority to the hard-chrome plated products.
E For combination with linear bushing, please select induction hardened products.

EP dimension requires M+3≤P.
E When M×2.5+4+N×2.5+4≥(Y), tap pilot holes may go through. When M×2+N×2≥(Y), priority is given to the effective length of tapped holes with larger diameters.
In such case, Y requires Y≥M×2.5+4+N or Y≥N×2.5+4+M.
