Steering head bearings

Post by steve » Wed Dec 30, 2015 9:26 am

Hello all

I have an old bike frame that runs conventional ball bearings in the steering head. These are ball bearings with a inner and outer race as part of the bearing.
The original bearings are SKF# 7206 and SKF 7205.

I am considering putting in taper roller bearings.

As a result of this I have a few questions.
Is there any reason this is not a good idea?
Are they generally a drop in solution if I can get the correct sizes or do I need additional spacers between them like when a wheel has tapper roller bearings?
Can anyone recommend a good source of technical information if this question can't be answered here.

Contact your local bearing supplier. Give them stock bearing numbers and ask them the same questions. From my experience the tapered rollers take up no more space than a couple of mils which is within your headstem's capabilities. However your bearing guys should be able to tell you that.

Tapered rollers take a lot more strain than balls and are particularly beneficial with extra rake. Make sure you grease them well. This can be done by hand... just a bit messy.
