I have a broken bearing on the Roller Rack Assembly that is part of the bedroom slide mechanism. It is the Aluminum block that the electric motor bolts to that is part of the rack and pinion system that moves the slide in and out. One of the bearings failed and was locking the slide so it wouldn't move. I ended up taking the bed completely out so I could get to everything. Also had to take the track out that is the pinion portion of the slide mechanism. The Roller Rack Assembly is not made any more. I have called about 20 RV salvage yards to no avail. Obviously called alliance coach and they gave me the PN (DN12066 or DN13783) for the Assembly but no one makes it. Still trying to find out who the original manufacturer is. Heading out now to a machine shop to see if the can match the bearing. The bearing has a stud AS PART OF IT SO IT CAN BE ATTACHED TO THE Assembly. Anyone with any ideas where I might find the Assembly or know of the manufacturer? Hopefully the 2 pics I tried to attach comes with the write up. Thanks.

Lippert is probably the mfg -- Bill Willard

Have you looked closely at the bearing, in most cases the manufacturer and PN are stamped on them.

If not take it to a bearing supplier in your area and they should be able to find a match. The set screw on the side is pretty common in a number of applications to keep the bearing in position.

There are no numbers on the bearing. I was hoping there was. I will check with slippery. I am going to a machine shop tomorrow to see if they can get a similar Bering and stud. I took one of the bearings apart and the needle bearings were dry and some scaring on the race was noticeable. Would think they would put rubber seals to keep the grease in the bearings. Thanks for the feed back.

If you can try and get a sealed bearing that is prelubed.

If you post the dimensions we might be able to source on line. Several large manufacturers out there so I'm sure you can source one.

After doing more research and a little help from a local machine shop it looks like Lippert is the manufacturer of the slide mechanism for the Camelot (probably the complete Monaco line). I am calling them first thing Monday morning. On line it showed the same roller for $14.25. I am buying 4 and replacing all of the rollers. Sure don't want to R&R everything again. Thanks fo everyone's help.

After finding and ordering all 4 of the bearings from Lippert, I received them and installed them in the Roller Rack Assembly. The only problem was the star screw on 3 of the rollers were one size and the other one was smaller in size, So I was a little baffled about that. Anyway everything is installed again and the slide works great.
Now I have a problem with the gas strut that holds the bed up. PN 4455QK from FSI was replaced about 4 years ago because the old ones weren't holding the bed up any more. Anyway, I re-installed the struts and tried to put the bed down and the struts will not retract. I put a lot of force on the bed but it wouldn't budge. I took off one of the struts and no matter what I did I couldn't get the strut to retract at all. Before I took off the struts to remove the bed platform they worked great, actually it took a lot of pressure to lift the bed or to put the bed back down again. Any ideas???
