NordicTrack 505 dual End Rollers Front / Rear Replacement screw in Axle Parts 

What you see is what you will receive, 4 dual rollers for front or back of 505 vintage ski machine, with threaded axles and nuts.

I have two listed, so if you need to replace all 8 on one machine buy both sets, I will give you a deal on shipping.

I have other 505 parts and other NordicTrack parts available in other listings and will combine shipping when possible.
