The rollers are identified to indicate: - the series and type; - the spindle: as standard design or according to the basic abbreviation which corresponds to the required design as indicated in the relative table; - roller diameter and the abbreviation according to the basic design or to upple-mentary abbreviations as shown in the relative tables; - roller length C. Series Type Spindle diameter Spindle design Special spindle design Roller diameter Basic tube design Special tube design Length C * Note: Specify the dimension of “ch” if it is non-standard.

In the first column of the table abbreviations are indicated according to the basic roller designs. There are supplementary designs possible as indicated in the table, as long as the corresponding abbreviations are not represented in the same column. In the indication of the ordering code abbreviations are listed according to the horizontal Tube designs column order.

^ Rollers In the table basic designs of spindle are indicated in varying arrangements: Basic design: spindle in steel S235JR (UNI Fe360, DIN St 37) Supplementary design: J = spindle in steel S235JR (Fe360) zinc plated I = stainless steel spindle Spindle design Basic abbreviation with internal flats = 15 20 25 30 40 K orthogonal hole (for garlands) d = 15 20 25 30 40 * B = metal bush N = polycarbonate bush

Si with diameter reduction d = 15 20 25 30 40 Spindle extensions that are not symmetrical, dimensions of flats “ch” that are different to the designs shown in the table, are all possible but should be specified clearly in the order with a sketch.
