Stoltz Rollers do not have a separate bushings that can come dis-lodged or dry out and crack, the inner sleeve is aluminum and is ideal for supporting and allowing the roller to spin.

Rollers in general are near essential to the loading and unloading process. Not only can they ease the process, but they also protect your boat from impacting the trailer at crucial points.

Typically, a keel roller mounts inside of a bracket, often referred to as a roller bracket. This roller would have a shaft running through its center, with caps, pins, or nuts holding it in place. This assembly is they bolted or u-bolted to the trailers cross-member.
