Title: Stradic 4000XG-L bushing to bearing question
Post by: chris_w on April 09, 2025, 08:27:03 PM
Hi there,

I'm in the process of upgrading bearings for the factory bushings in this reel.  There's one bushing I'm having a hard time finding a bearing for - it's the bushing that sits within the Rotor Nut:
Part number 20272  Spool Support Bushing  -or-  Main Shaft collar

Does anyone know if there is a bearing made to swap out this bushing?

Thanks

Gotta get out the calipers for this one. A ball bearing of the equivalent dimensions will work. May or may not make a difference, but that's never stopped me before.

Is this any help ?

I have one reel with a spool ball bearing, the Suveran. I don't really see the need for it. It's located up on the top.

all metric bushings should have a matching metric bearing.

It's the bushing below this one - I've already done the video swap.  Thanks

The measurements with the calipers are:
ID 4.3mm
OD 9.8
W  2.56

Haven't been able to find a bearing this size but maybe I haven't looked hard enough

4.5x10x2.5 is my guess. Digital calipers vary.

Keep in mind that this bushing has to be an axial bearing surface as well as a radial one, as the spool shaft will make contact with it especially if the reel is loaded. The spool shaft may not slide as nicely against the steel inner race of ball bearing as it does on the bushing.

So it's has a rotor/pinion bushing?

It has a pinion bearing, that is not this part. This reel has a "budget" version of what is usually called a "floating spool shaft". In most reels the inside surface of the pinion gear spins against the spool shaft, and when there's a load on the spool it can pull the spool shaft sideways against the pinion gear and create a friction point. A feature previously reserved for very high end reels (think Stella, Saltiga) was to have a ball bearing inside the rotor nut, often with a nylon top-hat bushing inside it, to isolate the spool shaft from the pinion. This is a pretty complex part, and a cheaper way of achieving largely the same thing is to just put a nylon bushing in the rotor nut.

Gotcha, thanks. I recall reading something about that, maybe in an Allen Hawk review.
