I think that Sauron and the Balrog had the same relationship as he and Shelob. Sauron used Shelob as a guard, although he never had actual contact with her.
I think he considered the balrog to be an extra guard at Moria, and so he left him alone. The balrog on the other hand was content with being left alone.
Think of the seven year-war between orcs and dwarves. If the balrog had not been there, the dwarves would have retaken Moria.
Conclusion: The balrog and Sauron may never have meet, but they probably had some sort of agreement like: You (Sauron) keep out of Moria, and I (balrog) keep it clean of dwarves and other enemies.
