Does the Lippert 115613 J-4 Slide-Out Roller Assembly have ball bearings and is there an adjustment lock
I have a 2000 Flagstaff 5th wheel that I am rebuilding and the rollers needed to be replaced. The Lippert 115613 J-4 Slide-Out Roller Assembly would work perfectly but I need to know if the rollers are on bearings and is there an adjustment lock to keep the height locked in. The clearance on these will work as will the adjustment available. I am fabricating mounting plates to allow removal for maintenace from the outside and need to know how are these lubricated. Been using your products for my rebuild and look forward to your reply for getting these rollers.
