Up until the German invasion of Russia in 1941, the SS was generally only used as motorized support for any armored assaults by the Heer Panzer divisions. In 1941, the Das Reich division was the first to receive some armour, but only in the form of Sturmgeschütz. It was only in the middle of 1942 that the Waffen-SS were finally granted their own armoured divisions.
For an excellent reference on the whole Wehrmacht/Waffen-SS organization, just Google germanwarmachine. It should be your first hit. For information related to this thread, click on the Waffen-SS topic on the left and then on 1942-The SS Panzer Divisions in the right column.
