Remove the bearings and take them to your local Industrial Supply retailer, they should be able to cross reference and get you the ones you need.

It is a bushing of some sort. What is the make and model of the rowing machine? Have you checked with the manufacturer?

I found them at fitness-superstore.ca they are 19.00 each.

Most rowing machines can be stored vertically to take up less floorspace. This is also where the caster wheels can come in handy to help you move the rower to a corner, nook or cupboard, and the folding nature of some rowers like the Concept 2 can be helpful for storage in a small space.
