Requirement for drum shaft extension: drawing No. with “-S” as postfix refers to double shaft extension (e.g. 100A108Y (Z)-S); drawing No. without “-S” as postfix refers to single shaft extension.
Requirement for drum surface: all are cast rubber surface. Drawing No. with “Y” as postfix refers to right-direction herringbone, with “Z” as postfix refers to left-direction herringbone, with “YZ” as postfix refers to diamond shape (omissible).
II. Bend drum
Requirement for drum surface: drawing No. with “G” as postfix refers to smooth face drum; drawing No. without “G” as postfix refers to rubber face drum.
