What does FF mean on a bearing?

No, you should not use WD-40 to clean skateboard bearings. WD-40 is designed for removing rust and grime, but it is not a lubricant and will dry out the bearings. Instead, you should use alcohol or other silicone-based lubricants to clean and lubricate your skateboard bearings. Additionally, you can use household items such as motor oil, canola oil, or vegetable oil to clean and lubricate your skateboard bearings.

ABEC-5 bearings are generally considered to be the best grade of bearings for cycling applications. ABEC is a rating system created by the Annular Bearing Engineering Committee (ABEC) that includes five tolerances classes: 1, 3, 5, 7, and 9 with 1 being the widest and 9 the tightest. Grade 5 bearings have tighter tolerances than Grade 3 bearings and are better suited for high speed applications. Grade 5 bearings also use higher quality chromium steel balls than Grade 3 bearings. In general, if an application does not require extremely high tolerances, an ABEC 1-3 bearing is usually the better choice

Yes, you can use 70% isopropyl alcohol to clean bearings. However, it’s important to note that isopropyl alcohol is a harsh solvent and can damage some materials, so it should be used with caution. To do this, put the bearings in a container with a lid and fill it to the brim with isopropyl alcohol. Cap the container and shake for 5 minutes. If your bearings are still coated in nasty, repeat the process. Set the bearings out to dry. Yes, you can use isopropyl alcohol to clean bearings.

The best liquid to use for cleaning bearings is a solvent such as Acetone, Methyl Ethyl Ketone, Citrus Cleaner or Denatured Alcohol. These can be found in the paint section of local hardware stores. Other household items with citrus content such as vinegar and lemon juice may also work, but should not be used as they are dangerous to use. Speed Cream should be used instead of water-based cleaners like citrus cleaners.

WD-40 White Lithium Grease is a great lubricant for bearings, but it should not be used as a replacement for the appropriately selected lubricant. WD-40 does not have a particularly high viscosity and does not contain anti-wear additives, which are often required for bearing applications. Additionally, WD-40 is designed for removing rust and grime, not as a lubricant. Therefore, it is not recommended to use WD-40 on skateboard bearings. Alternatives to WD-40 that can be used to clean and lubricate skateboard bearings include motor oil, canola oil, or vegetable oil.

It is recommended to grease a bearing while it’s running, as the grease will be less viscous under operational conditions and should contain the right lubricant for the bearings. Grease is often used in 80-90% of bearing applications due to its ability to reduce friction, wear, and noise. When re-greasing, ensure that the motor is at operational temperature and remove any lower drain plugs before adding grease. Common mistakes include not using enough grease or applying too much pressure when greasing. It is not recommended to grease a bearing while it is running. Greasing a bearing while it is running
