Most likely they are the newer oil lubed, "sealed" rollers.

Looks like you got one or each going by the pictures,there is a special nozzle needed to fill the oil filled rollers,that undercarriage looks to be well worn,the roller in the second picture looks like it loose,there is a crack in the link rail in the first picture you should have it welded before it breaks right through the link,there is not a lot of life left in the undercarriage.

looks like the rollers are worn also--the roller flange is wearing into the bushing boss on the track links
