Looking for a replacement for this heavy duty closet roller bearing made by Nordahl in Burbank, CA c. 1957. My door is old and very heavy. Thanks for your help! Steve

Hello,

Unfortunately, we do not carry an exact match for your part but we have recommended our 23-001 with a 3/4" wheel and 1/4" offset as a possible replacement for a similar part in the past, which might work for you as well. Please compare this part to your original roller and see what you think. Thanks for posting!

Part 23-001 looks like a real possibility, if it can handle the weight of this extremely heavy door. Thank you for the photos with specs! Can you tell me if the wheel is a ball bearing; and what its weight capacity is? Thank you!

The 23-001 wheel is not ball-bearing and, unfortunately, we do not carry a version of this part that is. The maximum weight capacity for this roller is 50 lbs.
