Bushing or Needle Bearing
« on: December 31, 2020, 07:34:12 AM »
For you long glide users, do you use a bushing or needle bearing in your tailshaft in a FED? Just wondering the do's and dont's. Thanks...
If it jams force it, if it breaks it needed replaced anyways

I use a bushing. Same bushing and seal for over 10 years. No leaks, no issues.

needles bearings require a coupler or yoke etc that is designed for needles and I think is hardened different--Mark Williams and others offer them both ways--I would just go bushing--a needle there can cause premature wear on wrong coupler and any drag reduction would be next to nothing--bushing is way less trouble potential

Yes a roller bearing tail housing requires a different yoke. Either is fine, as long as the alignment is corret the wear should be minimal.
