Based on the official Bosch Rexroth documentation, the A4 stroke code you are asking about is not a standard option for the HVBS cylinder range.The standard code for a 5 mm stroke length is simply A . The A4 designation likely represents a custom, non-standard variant or a combination of the mounting type and stroke code. This conclusion is supported by a product listing for an HVBS02A4VG cylinder, which confirms that this specific model variant is manufactured by Bosch Rexroth .📋 Standard Ordering Code BreakdownFor your specified cylinder, the standard code would be structured as follows:Type: HVBS - Single rod differential cylinder .Range (02): This specifies your requested piston diameter (25 mm) and piston rod diameter (16 mm) .Stroke Code: A - This is the standard code for a 5 mm stroke .Mounting/Seals: The remaining code (e.g., 1 V) would specify the mounting type and seal variant.Note on A4: The A4 you mentioned is not a standard stroke code. It may represent a custom variant or a specific configuration not covered in the standard documentation, but the base product type and dimensions remain the same . For definitive confirmation of this exact variant, contacting Bosch Rexroth directly is recommended.
