I got a good price on some after market wheel bearings for my CBR 1000F. They're SKF. Can anybody comment on whether Honda OEM bearings are any better? Any opinions out there?

 

SKF make good bearings - just as good as any other good manufacturer out there.
Buy bearings with protective seals built in - they last longer and keep cr-p out of the grease.
My 2c worth.
When replacing bearings, PUT THEM IN THE FRIDGE/FREEZER OVERNIGHT before doing them.
They'll go in much easier because they will shrink a micron or two

 

Honda won't make their own bearings , they will buy them in from another specialist , if it's a good quality product use it

Ditto to what Shadow says

 

Thanks Shadow!

 

You too Hawkwind, thanks!

 

I'm running SKF in my Blackbird - cheap as chips compared to OEM honda bearings (I think honda use NSK)

DO NOT use "C3" clearance bearings for the bike - C3 is for continuous high speed running - ie 15,000 rpm + ( and that would be wheel rotation speed, not crankshaft - haha )

Just get standard clearance SKF bearings.

 

What were the part numbers for the SKF bearings? I'm planning some PM for the next time I take the rear wheel off.

 

Hey Deano: Why do you say not to use C3 bearings? Wouldn't they be better than standard clearance, especially for wheel bearings? Any other opinions out there?

 

C3 bearings have extra clearance and only get to the best running clearance at continuous high speeds - ( 15,000 rpm or more )

The normal diameter of a motorbike wheel/tyre is around 60cm

60cm x 3.142 = 1.885 meters per revolution

530.5 revolutions per min = 1 km per min = 60 kmh

2652.5 revolutions per min = 5 km per min = 300 kmh

At 2652.5 revolutions per minute you are hardly even stressing standard bearings never mind trying to get C3 bearings up to the correct running temp for correct clearance.

Stick with standard spec - they will last longer.

I'll get my engineers anorak now and leave the buliding - haha

 

Thanks Deano!
