179-6915: 0.5mm Thick Shim

A Shim is a thin, flat piece of metal used to adjust the clearance between two components. In a piston pump, the shim adjusts the clearance between the piston and the cylinder wall. Attributes: • Prevents the piston from rubbing, which could cause wear and tear • Allows the piston to move freely within the cylinder Applications: A Shim is typically used in order to support, adjust for better fit, or provide a level surface. Shims may also be used as spacers to fill gaps between parts subject to wear.
