Do barbells need to spin?

Are bushings or bearings better for barbells?

As a general rule, the more bearings in a barbell, the smoother the spin. Barbells with bushings are cheaper, you won’t get quite as nice spin (or friction free movement) on a bushing only bar but they are fine for lower weights and most home gyms. They are also great for powerlifting where spin is not as important.

Whats the difference between a bearing and a bushing?

There isn’t really a difference: a bushing is a type of bearing. In general, a “bearing” facilitates movement between two parts while reducing friction. A “bushing” is a specific design of bearing used for certain applications. To summarise: a bushing is a bearing, but a bearing is not always a bushing.

In other words, bronze bushings are self-lubricating. Self-lubrication is the first major advantage of using bushings over ball bearings. Another major benefit is cost. Bronze bushings cost between six and ten times less than linear ball bearings.

How do you keep weights from loosening?
