For light weight pulleys has anyone looked at ceramic rings?

My wife wanted a roll up awning on the front window (and bedroom window) 
facing west.  The awning is made out of metal oval tubes edge connected 
(not end) that can roll (after a fashion) to form a large roll, above the 
window, near to the soffit.  The rope used goes through ceramic rings, not 
pulleys) to change direction of pull of the rope.  I have not seen any 
available (but in this small town that is not surprising, I cannot find any 
cold galvo or zinc rich paint unless it is expensive sprays for the 
automotive body trade)  For occasional use, say on a mast to pull up the 
antenna wire, or even coax, these might be OK.  No rust, no jamming, just 
sliding,
