A spacer block is a precision-machined component used to maintain a fixed, controlled gap between two mating parts within an assembly. In compaction equipment like the RD27-120 and RD28-120 tandem rollers, spacer blocks ensure that rotating or load-bearing components stay correctly positioned relative to one another, preventing contact, misalignment, and uneven stress distribution. When a spacer block wears, cracks, or is missing entirely, adjacent components begin to shift under vibration and load, accelerating wear across the assembly and potentially leading to more extensive mechanical damage.
