Q:how do you clean Ur bearings?Ty!?
yep, okorder.com/
Q:what is the advantage and disadvantage of water-lubricated bearings?
The main advantage of a water cooled bearing is you can use the a portion of the water from the pump discharge to lube the bearings. That way you can always be assured of the lubricating fluid supply and do not have to relay on another pump. Some pumps do use another source, especially if the water being pumped is dirty, but it is still cheap and non-contaminating if some leaks into the pumped fluid. However, water is not always a good lube especially on pumps with high speeds and/or mechanical loads. Water is not very viscous and becomes less so with increased temperature. Even small 3600 rpm pumps will use oil for lubrication. Some large, high pressure pumps will have their own oil pumping and cooling system for the bearings.
Q:Do all skateboard bearings have 2 sides?
most of them have two sides. I believe that abec 7 bearings have two sides but i am not sure. google abec 7 bearings and that should give you the answer
Q:Do rear wheel drive cars have rear wheel bearings?
Of course. You need the wheels to spin don't you?
Q:What are good set of wheels, bearings and spacers for outdoor rollerblading?
If okorder.com they should b able to help you
Q:Help with vectors and bearings please!?
using compass bearings: (2,60°) + (1,90°) = (2.9093, 69.8961°) - - - - - - (2,60°) = (1.7321, 1) - - - - - - (1,90°) = (1, 0) - - - - - - (1.7321, 1) + (1, 0) = (2.7321, 1) - - - - - - so: a) 2.9093 km b) (1.7321, 1) and (1, 0)
Q:Does skateboard bearings work for razor scooters?
Yeah they should, skateboard and Rollerblade bearings are the exact same bearings, assuming razor scooters take Rollerblade wheels, then yes they would. Go for the swiss bearings....you'll be floating!!! lol
Q:which skateboard bearings are faster?
black panther are no contest
Q:how do u clean skate bearings?
you take s socket wrench and loosen the nut and take it off and take off the washer , than the wheel than the other washer . Don't lose ur washers !!! Do this to each wheel . Take about 8 Qtips or more or less depending on how dirty ur bearings are , take the Q tip and rub the dirt off of the bearing . Each side and in the insides .
Q:Do skateboard bearings need to be broken in after cleaning them?
It might seem that way but the bearings are gonna be fast.. You should ride the board to test the bearings .. Spining them helps a little but when you ride them your weight is on they will give you a better feel of how they perform.. They probably faster than what you think .. yeah just go ahead put the spacers back.. It will protect the bearings trucks.. Do to the friction they might share here there.. You have like the best wheels bearings outhere.. Bones is the best when it comes down to wheels bearings.. Lucky dude.
