Post Steering Stem Bearing Size

Just in case anyone wanted to swap their ball bearing steering head bearings for some tapered roller bearings i do not have the part numbers.

But I do however have the dimensions of the OEM bearings so you can
call your local shop and see what they have.

The upper bearing measures:

d= 26mm
D= 47mm

Height= 15mm

The Lower bearing measures:

d= 30mm
D= 55mm

Height= 17mm

d = inside diameter
D = Outside Diameter

height of the bearing across outside faces

Hope this helps, if i track down part numbers from NSK of SKF i will post them here!!

Cheers

Lower Bearing SKF Part # 32006 Single Row Tapered Roller
NSK Part# 32006x Single Row Tapered Roller

Upper: Bearing # is 32005 should be able to source it based on that.

Also Found this site, which has both bearings for $40 with dust shields.
I ordered a set...
