Get The Right Lubricant
Your skateboard runs on bearings and the wheels roll over a surface. If the bearings aren’t lubricated correctly, it can cause a lot of friction between the bearings and wheels and eventually your axels could wear out.
What you need to make sure you have is the right lubricant that isn’t too thick or too thin. There are 3 types of bearings you should be aware of:
- Standard–which are waterproof
- Abec 3–which are water proof, but not rated for as much friction
Prepare the Bearing
First, we need to inspect the bearings for damage. Take the bearing out of the packaging and use a magnet to check for chips or cracks. If the magnet doesn’t stick, the bearing isn’t salvageable. If the magnet sticks to the bearing’s edges, it is still salvageable, but should be checked for damage anyway. If you find that the bearing has some damage to it, you can still use it with some lubrication, but don’t expect it to last as long as it should. If there is no damage, you can move onto step 3.
If you had to replace the bearings because of damage, check the bearings again before you install them. If there is any chipping, dents, or a scratch, you should not install the bearing as it may not stay in place and may cause damage while you skate.
Remove Old Grease.
Once your bearings are cleaned, the next step involves removing every last scrap of old grease. If you want to get the job done quickly, you can use an air compressor to blow out the bearings. You’ll need about a quarter of a second of air pressure to clear the bearings of grease.
Lubricate your bearings
Now that you’ve cleaned your bearings, it’s time to apply some lubricant. Pop some into the outside cup and cover the bearing’s axle with a bit too. This will help your bearings spin more easily. Give your wheels a quick spin on the floor to see if it makes a difference.
Finally, Apply Fresh Oil
After you’ve cleaned your bearings well, re-lubricate them with wd40. It’s simple: Put a little bit on each bearing and the spacer. You can also put some in the middle section of the bearings (for “between the bearings” lubrication). Personally, I apply the wd40 to the outer edges of the bearing, as I feel that is where it is most useful. That allows a bit of wd40 to get sucked into the main bearing to help keep it well-lubricated.
Replace the ball bearings
Skateboard bearings need to be oiled. Many of the bearings on the market come pre-lubricated, but you will need to oil the rubber seals. To do this, simply pour a little oil on the seals. It is also a good idea to give your bearings a good spray over. This will help to keep your bearings going smooth and silently.
Replace Skating Surface
Before you can start to skate again, the worn away streaming is replaced.
Step 1: Place the spacers back on
Step 3: Clean off the grinding wheel
Step 4: Grind the surface of the ground with 1000 grit sandpaper
Step 5: Remove the sandpaper
Step 6: Lightly sand the surface to a shine
Step 7: Replace the grinding wheel
Step 8: Wipe off the fresh grinding dust
Step 9: Inspect the skateboard bearing for the correct lubrication
Step 10: Replace the bearing and skateboard bearing cap screws
You can either use a conventional bearing lubricant or any other product that has a wax base. Liberally apply the lubricant to the inside of the bearing.
