DARK MATTER BEARING Skateboard Bearings OMG! (8)

[Important Note - For Overseas Customers]

Thank you for purchasing this product. Please read the following important notes carefully before using this product overseas.

1. Legislation and safety standards This product complies with Japanese safety standards. Please check compatibility with local regulations and safety standards before use in your country. Certain product categories (electronics, cosmetics, food, etc.) may require certification from the importing country.

2. About electrical products [Voltage compatible] When using electrical appliances, please note that they are designed according to Japanese voltage specifications (90-110V), so using them at a different voltage may cause malfunctions.

[Plug type] Our products use the Japanese plug type (A type or B type). Please use a conversion adapter if necessary.

[Important notes regarding transformers and adapters] A transformer adjusts the voltage to suit the requirements of the equipment. Conversion adapters only change the shape of the plug and do not adjust the voltage. Using only the conversion adapter without a transformer may damage the product.

[About responsibility] We are not responsible for any failure or damage caused by improper usage, such as operating the product without a transformer.

3. Language and manual Product instructions and displays may only be in Japanese. ✅【Product Contents】Bearings (pulleys) that are pressed into the center of skateboard wheels (tires). Eight pieces, enough for one skateboard, are packaged in a plastic case. ✅ [Product Development] Since starting out as FIZZ BEARINGS in 1998, we have repeatedly reviewed our designs, made improvements and model changes, and even changed our manufacturing factory based on feedback from the many top professional skaters we have supported, in order to achieve a balance between the seemingly contradictory elements required for skateboarding: speed and durability. ✅ [Size] The bearing's international standard number is "608," with an outer diameter of 22mm, an inner diameter of 8mm, and a width of 7mm. It's suitable for skateboards, longboards, surf skates, penny skates, roller skates, in-line skates, kick scooters, and run bikes. (Note: Some specialized products may not be compatible.) ✅ [Material of metal parts] The outer ring, inner ring, and rolling balls are made of high-quality high-carbon chromium bearing steel, which is further hardened to ensure hardness, improving load-bearing capacity and durability. ✅ [Retainer Material] The retainer is made of nylon resin with a low coefficient of friction, which helps ensure smooth rolling of the rolling ball even under the dusty conditions typical of skateboarding. ✅【Shield Material】The shield (lid) is made of rubber with a chrome core inside, which prevents dust and other foreign objects from getting inside the bearing and helps maintain smooth rotation of the bearing. When attaching to the wheel (tire), make sure the shield is facing outward (visible side). ✅ [ABEC Standard] ABEC defines the tolerances for various parts of bearing products relative to the design drawings. The larger the number, the smaller the tolerance, and the closer the bearing is to the actual size of the design. Therefore, since the friction coefficient is closer to the design drawing, a higher ABEC number does not necessarily mean faster speed. In Japan, JIS tolerance grades are generally used instead of ABEC.
