I don't have pictures of spinning reel line rollers on bushings. But it's a straightforward matter. It's Item # 6085 in the SF4000FD reel parts diagram on the shimano website:

The line roller is the thing on the bail that line slides over as it is wrapped onto the spool. It is mounted on the pickup end of the bail. On cheap reels there is no roller, just the wire of the bail that the line slides over.
On better reels there is a roller, a grooved wheel, mounted in the bail so as to "pick up" the line when the bail closes after a cast, so that the reel can be cranked to bring back the line. The better the roller rotates as line slides over it, the less is the tendency for twist that might be in the line to be "blocked" and built up just outside the roller.
Rollers that are mounted on a bearing tend to hang up less than rollers mounted on bushings--no guarantees though. A bushing is simply a metal tube that slips over a metal rod so that the tube (with a line roller attached to it) can rotate around the rod. Penn SSs and Zs have bushed rollers. Shimanos, Daiwas, Van Staals, and others have rollers mounted on bearings.
On conventional reels, the only thing even remotely related to spining reels' line rollers would be the part of a levelwind system that the line slides through, like on an abu 6500 CS, for example, but they have much less affect on the performance of the pickup function of a conventional reel than on a spinning reel.
Does that help?
