Sliding Door Roller & Bearing Kit
Replace your worn out bearing and rollers with this kit. The sliding door vertical rollers use a Delrin outer surface with a precision roller bearing in the center that is held in by a snap ring. The Delrin outers give it a very smooth/quiet operation. This kit includes both of the weight bearing vertical rollers/bearings along with the 4 horizontal bearings that guide the door.
Please note it will likely require use of a small bearing puller to remove some of the old rollers on your sliding door.
