What is the difference with bushings/bearings?

They are different mechanical parts or mechanical mechanisms. Either one will spin.
Bearings; will give you a smoother movement. Choose bearing; if you can afford it.
But, honestly, is not really necessary if you do not do olympic movements in your routine. Just Bushing it is fine for bodybuilding, or regular strenght training.

I do Olympic lifts, can you recommend any brands that are around the 4-5 hundred dollar range? I can't afford a $1200 Ivanko

Bushings and bearings are 2 different ways of letting the sleeve spin freely by reducing friction.
This is a bushing;
They can be plastic (usually nylon) or a soft metal like bronze. Simple how they work, put something with low friction between two moving parts.
This is a bearing;
It uses moving balls or rollers to reduce friction. However not all bearings are equal when it comes to bars. Pictured above is a ball bearing, a very bad choice for a barbell, they are cheap however and often used in conjunction with bushings. They aren't designed to take high radial load so can/will deform and seize up. What you ideally want are needle bearings;
These are capable of suffering huge radial loads which ball bearings suck at. However they are comparatively very expensive for a good needle bearing. Cheap needle bearings are as bad a ball bearings, the needle rollers are pretty delicate pieces of engineering and poorly made ones will break down.
So which is better? A good impregnated bronze bushing can spin almost as well as a good needle bearing bar, and certainly better than a cheap bearing bar. Bushings are also substantially more durable and require much less maintenance than a bearing as they have no moving parts, only very well engineered needle bearings will last as long but will require regular oiling.
It's not as clear cut as a bearing bar is always better than a bushing bar. You can certainly perform the lifts perfectly well on a decent bushing bar.
I'm not too familiar with your guy's market but for olympic lifts;
the Pendlay nexgen sounds awesome.
York also make a needle bearing bar that used to be IWF approved for $550 (has needle bearings) or a training bar for $385 (has bushings);

You could probably get these cheaper elsewhere or buying from York direct and getting crossfit discount.
These guys sell a USA made Chapman bar that is by all accounts excellent;

If you really like Ivanko bars you can step down to their Black Oxide OB-20 KG for an MSRP of $650, you just lose the stainless Steel I believe everything else is the same.

(This is actually my dream bar)
An Eleiko would be $779:

I'm mainly in agreement here with the above & the comment by Vic. Put bluntly: bearings for Olympic bars are mainly hype. It's marketing. You make a good bar with good bushings and respect tolerances and you don't need the other. I think you're spot on when you suggest (or at least imply) that a bearing bar is compensation for a less than well-made bar with bushings. My only quibble might be that the necessity to oil, regularly, certain high-end bearings.

As an add-on to this question...
How much free spin should one expect to observe on a typical bushing-style olympic sleeve? My bar is rather generic; it was sold with the rubber coated Body-Solid plate set. Each end can spin about one full rotation before stopping. Would it be worthwhile to purchase a 12mm hex key, remove the sleeves, and apply teflon grease? Or would the lubricant effect be negligible?

I would expect more free spin than that, though, free spin is not a good indicator of the amount of friction actually happening.
My cheap generic bars actually spin pretty well, granted there is enough play in the ends that I suspect this is really from little to no real metal to metal contact to cause friction, they also lack any real bushing.
My better bar turns very easily and very smoothly with no wiggle room. It doesn't have a ton of free spin though several seconds is all.
YOu bar isn't all that high a quality so I wouldn't expect to much.[]---[] Equipment Crew Member No. 11

If the bar has bushings and you can take it apart, do so. Clean out any grease or dirt and replace it with 3in1 oil, which is very thin and is best to float the bearings and give you the best spin. If your bar is truly cheap, it will not have bushings and you'll be $hit out of luck. Good luck.

Haha, yes it is a gamble if my bar has bushings. The sleeves do have some play, so that might not be a good sign. The reason I mentioned teflon grease was because it was recommended in this video.
They claim the grease doesn't collect dirt as quickly as oil and it withstands higher pressures. Although, I didn't see enough demonstration of the sleeve spinning when they were done.

I usually don't argue with the logic of cross fitters since they feel like they have reinvented the wheel, but here goes...
1) grease not only collects dirt just as quicly, but is less likely to release it, ie. you can flush out dirty oil with clean oil, you need to remove bad grease completely to get it clean again.
2) Oil has a much lower viscosity, there by allowing much less drag, between the bearing,and the bar, than grease does.
3) Olympic lifters, who depend upon the spin of the bar, have been using lightweight oil (such as 3in1) for years.
The only downside to oil, is that since it's thin it needs to be replaced occasionally, but all you need is a drop or two.
Realistically, the guy in the video uses grease because it's overall the best use for a business where the bars are abused, they don't want to do upkeep until a bar stops completely. At 4:08 he mentions that oil will cause a better spin. Ignore the comment about dealing with high pressures as he is talking out of his a$$.Last edited by twodog; 11-19-2013 at 08:23 AM.
