Tension silicone rubber grommet for Crown 300 series joysticks

For Seimitsu, Sanwa Denshi and Hori joysticks, springs of different tension are used to modify the joystick's tension. On the other hand, Korean Crown joysticks use high-density grommets made of silicone rubber. The most common grommet type is HST35, where a higher number (ST...) indicates higher resistance or tension.

Below is a guide listing the different types of grommets, silicone rubbers and bobbins used in recent Samducksa Crown models by manufacturer. This information is useful if you are looking to purchase the right grommet or bobbin for a specific model.
