Part for jealousies windows

Looking at your photo, it appears you need to replace the Torque shaft bearing. The problem is, I don't think your exact type is made anymore. We carry two that look similar: our 36-018ACK, used for a 1/2" diameter torque bars (used commonly on Crossly windows), and our 36-018G for 5/8" diameter torque bars (used commonly on Keller windows). Take a look at both to see if either matches up to your bearing.
