A sealing ring forms a pressure- and fluid-tight barrier between mating components, preventing internal fluids such as hydraulic oil or lubricant from escaping the assembly. On a tandem roller like the RD40-130 and RD45-140, maintaining these seals is critical to keeping drive and compaction systems operating at the pressures they were designed for. When a sealing ring degrades or fails, fluid leaks can compromise system pressure, lead to contamination, and cause premature wear or damage to nearby components.
