• Supports the dryer drum on the rear/under side to maintain alignment during rotation
• Reduces squeaks, grinding noises, and metal-on-metal contact caused by worn rollers
• Helps prevent drum wobble, uneven wear, and rubbing that can cause poor drying
• Works as part of the drum support system with the shaft and mounting bracket

• Disconnect power before starting service to avoid electrical shock
• Access typically requires removing the dryer rear panel or front bulkhead; follow your model's service manual
• Inspect the shaft, mounting bracket, and adjacent rollers and replace any damaged components to prevent repeat failure
• Use proper tools and moderate force
