Re:Bearing Cleaning - 14:46 10 Jan 05
If you're using good quality bearings, ie Powell & Peralta (Bones) etc., then
you can simply treat them as you would any other mechanical component:
- Place the bearings, usually four at a time, in a jar with a generous amount of petrol
- Seal tightly and agitate thoroughly
- Remove bearings from jar and clean individually with a toothbrush
- Carefully inspect the bearings and remove any built up crud from inside the bearing race
- Dispose of the petrol (and the muck) in an environmentally sensitive manner
- Clean the jar, add more petrol and agitate again
- If there is still muck in the petrol repeat 1 - 5
- Dry the bearings, ideally with compressed air, or with a lint free cloth (paper towels tend to leave fibres behind) but make sure they are really dry or step 9. is a waste of time as the petrol will render the grease ineffective
- Carefully apply a high quality grease (not oil) or specialist product such as Powell & Peralta Speed Creme to each side of the bearing race and ensure that it is evenly worked through all the bearing cages
- Wipe off any excess material
- Reassemble and enjoy quiet and smooth running bearings...
I do this every six months or so, depending on how much skating I'm doing, and my Bones bearings have been spinning smoothly and quickly for over five years!
I remain unconvinced that Ultrasonic Cleaners and Citrus Degreaser are any sustitute for Petrol and Attention To Detail
