| Basic version: > with cutting gap does not allow any supporting function. For supporting function, cutting gap = 0 and spiral groove are used. 1) The cross-section usually depends on the profile of the seal. The value of the cutting gap depends on the material and temperature. For detailed information, please refer to the personal profile description. | |||||
