What does the model number of an OREKU press mean?

        What does the model number of a press mean?
     The first letter represents the class designation, where “J” is the abbreviation for mechanical press.
    The second letter symbolizes the sequence of variations of the same model. This is the second variation of the “B” brand.

The third and fourth digits represent the column and group designations, where 2 stands for the open two-column design and 3 for the tilting body. When combined, they represent the way in which the press is constructed. 31 represents an enclosed single-point press; 11 represents an open, single-column, fixed-bed eccentric crank press; and 21 represents an open, single-column, movable-bed eccentric crank press.
    The values located after the horizontal line represent the main parameters, usually the nominal pressure as the dominant parameter, which is expressed in KN.
