How do you lubricate table rollers?

The rollers in my Buddy table are not turning smoothly anymore. I don't see a way to oil/grease them. How do you do it? Or do they just have to get replaced?

Below are pictures of them

Just get new ones. They are probably the 1.9" dia ones with hex shaft HERE (https://www.mcmaster.com/#standard-rollers-for-conveyors/=1bepsd3)
