Bearing cleaning and lubrication

To ensure optimal running conditions for your bearings, it is very good to clean and lubricate the bearings on a regular basis. Doing that, the speed and durability of your bearings is preserved.

Notice: Avoid water & sand. A bearings lifespan will be shortenend drastically when riding /stored in moist surroundings.

How to clean and lubricate bearings

Step 1

Required tools: Cleansing agent (grease dissolving fluid like Fluid wash, a waterproof container, a drawing pin, a little brush and new oil/grease (order a complete set).
Take out all the bearings of the wheel. Watch youtube video on how to remove bearings from a wheel with a 6mm spacer or a 8mm spacer

Clean wheels and frame at the areas where bearings were fitted.

Step 2

Clean all outside areas of the bearings, so the beraings are completly free of dirt.
Check if the bearings is a closed or open kind. Only open bearings are maintainable (closed bearings can be maintained, if you use a tool to carefully remove the shield, but the shields cannot be reused then).

Clean the outside areas of the bearings

Step 3

Remove the seal from the bearings with a drawing pin (not all bearings have a shields).
On some bearings a small C-clip holds the seals (in that case it is shields, not seals). This C-clip must be removed with the drawing pin before the shield can be removed.
Clean seals and C-clips if supplied.

Step 4

Clean the bearings in a container with cleansing agent. Use a small brush to carefully remove dirt from the inside of the bearing, also do this by shaking the container for a few minutes.

Clean bearing with a small brush, Always brush inside-out.

Step 5

Remove bearings from container and spin out the rest of the cleansing fluid. Also do this by blowing out (preferable with compressed air) the fluid. Place the cleaned bearings on a piece of clean cloth or kitchen roll.

Bearings have just been removed from container with cleansing fluid.

Step 6

Test if the cleaning process was succesfull. Hold the bearing on the inner ring and give the bearing a light spin. If the bearing does not rotate freely and/or a you hear an unmistakeable crunchy sound is it because the bearing is not cleaned thoroughly enough. Then you should repeat the cleaning process with new (or filtered) cleansing fluid. For very dirty bearings it can be necessary to repeat this 2-3 times.

Test if the bearing is cleaned throughly, by spinning it as shown.

Step 7

Place the bearings on a clean cloth or kitchen tissue. The bearings are now ready for oil or grease. Use 1-2 drops of oil (not more, as it will attract dirt) or 3mm grease evenly distributed around in the bearing.
Make sure the oil/grease is distributed well by spinning the bearings (can be done very effectively by mounting the bearing on a drilling machine)

New oil is carefully dripped into the bearing

Step 8

Finally the seals or shields with C-clips are mounted. If you clean your bearings on a regulary basis, then it is not necessary to mount the seals/shileds, just make sure the open side is placed at the inside of the wheel.

Smear a very thin layer of oil on all outer metal-areas of the bearings, then corrosion in the future is prevented.

Finally place bearings in the wheels and in the rollerblades.

Seals are mounted on the cleaned and lubricated bearings

After cleaning an lubrication

After cleaning and lubrication of the bearings, you should be aware of that you might need to run a few km before the oil/grease is perfectly distributed in the bearings, and therefore before the bearings runs optimally.
