This shim is made for Busch COBRA NC0630B screw vacuum pumps. It measures exactly 0.50 millimeters in thickness. You use this shim to set the correct axial clearance between the rotors and the pump housing. Getting the right gap keeps your pump running quietly, efficiently, and without internal damage.

Shim, 0.50mm - Part # 433544883A
This is a thin, flat metal ring. Technicians call it a “shim” or a “spacer.” You place it behind the bearings or gears inside the pump. Its only job is to control the gap – or “axial clearance” – between the spinning screw rotors and the stationary pump housing.Every pump model has a factory-specified gap. For the Busch COBRA NC0630B, that gap might change depending on wear and tear. The 0.50 mm shim gives you one specific thickness option. When you rebuild your pump, you may need this size to bring the rotors back to the perfect factory position. It helps you hit the exact clearance your pump was designed for.
