Spacer
Mack

This spacer sets precise separation between components to achieve correct alignment, preload, and clearance in assemblies such as pulleys, gears, or bracketry. By maintaining defined distances, it helps prevent contact wear, reduces vibration, and contributes to uniform load distribution across fasteners. Material choices are made to withstand axial and radial stresses while resisting corrosion in difficult environments. Correct spacer thickness and outer diameter ensure proper seating against mating surfaces, enabling smooth operation without binding or rubbing. The spacer supports easier disassembly for service and replacement, supporting reliable maintenance practices. Source One Parts Center
