D.B.P.2019608 and JAP.Pat.778322 on Your Centaflex A Coupling

What Do D.B.P.2019608 and JAP.Pat.778322 Mean? 

The designations D.B.P.2019608 and JAP.Pat.778322 refer to patent numbers associated with Centaflex couplings, specifically the CF-A series, produced by Miki Pulley. These flexible rubber couplings are utilized in various industrial applications to connect engine flywheels, shafts, and other power transmission components. If you have found these markings on your coupling element, this is a strong indication that your machinery was originally equipped with a genuine Centaflex A coupling from Miki Pulley. These patent numbers confirm that the coupling follows the original manufacturing specifications, ensuring quality and reliability. 

How to Identify the Correct Replacement Element? 

While these codes confirm authenticity, selecting the correct replacement requires additional information from your existing coupling setup. Follow these key steps to ensure a proper match: 

Fitment Type:

Centaflex A coupling elements come in two main fitment types: 

Type 0: This type utilizes screws for secure attachment to the flywheel and hub. 

Type 0-S: This type employs pins for secure attachment to the flywheel. Screws attach elements to hub. Pin versions have higher capabilities of axial movement while operating. 

Why Does NEW Coupling Element May Look Dirty? 

Genuine Centaflex A elements may sometimes appear dirty or slightly coated—this is actually a sign of OE (Original Equipment) quality. Centa, as the producer, applies a special protective coating on Centaflex A elements to shield them from UV light exposure, significantly prolonging their service life. 

If you are unsure whether your element is new or used, inspect the tightening areas where the coupling was fastened. Used elements often show visible scratches or pressure marks in these places, indicating prior installation.
