FAQ

How do C and C0 differ for SRH25VE?
C0 is the static rating used for the static safety factor check at rest or low speed; C is the dynamic rating used in the life formula. They describe different conditions and are not interchangeable.
How much stronger are two blocks than one?
For this model the two-block allowable pitching moment rises from 85,112 to 391,311 kg·mm. Select per catalogue table 2.x and remember to apply the contact-factor fc derating.
How many blocks and rails fit this model?
Size 25 is available both as separate blocks and rails, and as factory-matched sets with higher combination accuracy. Rail length is cut to your stroke; accuracy N/H/P/SP and clearance ZF/Z0/Z1/Z2 are all orderable.
