In a manufacturing context, the numbers following the prefix usually denote the piston diameter (bore) and the stroke length. A "426" designation often points to a custom or specific configuration within the ISO 21287 standard.
Given the precision required for these parts, using genuine OEM parts is usually recommended to prevent "stiction" (static friction) or premature failure.
These units are designed for high-cycle rates and longevity, featuring "C" class cushioning (often self-adjusting PPS cushioning) to reduce impact noise and vibration. 2. Automotive and Hardware Applications
The "ADN" line is known for being up to 50% smaller than standard cylinders, making them ideal for tight spaces.
While the exact specs depend on whether you are holding a cylinder or a circuit board, products labeled with this keyword generally share these traits:
Some aftermarket brake pads or rotors use alphanumeric codes similar to ADN-426 to categorize fitment for specific Japanese or European car models.
Designed for low-tolerance environments where "good enough" isn't an option.
If you are tasked with replacing an ADN-426 C component, keep these tips in mind:
