The Bomag 05800504 Back-Up Ring is a genuine OEM component designed for the BC 601 RB refuse/landfill compactor. Sourced directly from Bomag, this back-up ring delivers the exact material grade and dimensional tolerancing required to maintain hydraulic sealing integrity on the BC 601 RB. As an authentic OEM part, it meets the same specifications as the original component installed at the factory, ensuring a dependable, lasting fit within the hydraulic assembly.
Key Features
- Hydraulic Sealing Precision — manufactured to OEM material and dimensional specifications, ensuring the correct compression and extrusion resistance needed in hydraulic cylinder and valve applications
- Direct OEM Replacement — slots into the existing hydraulic assembly on the BC 601 RB without modification, matching the original groove dimensions and pressure ratings
- Confirmed Fitment — verified for the BC 601 RB refuse/landfill compactor under Bomag part number 05800504
- Prevents Seal Extrusion — supports the primary O-ring under high-pressure hydraulic cycles, stopping gap extrusion that leads to rapid seal failure and fluid loss
- Genuine Bomag OEM Quality — authentic part backed by Bomag's OEM supply chain, giving you confidence in material consistency and long service life under the demanding conditions of landfill compaction work
A back-up ring works alongside a primary O-ring in a hydraulic sealing assembly, preventing the softer O-ring from being pushed into clearance gaps under high operating pressure. Without a properly functioning back-up ring, the O-ring deforms and extrudes, causing hydraulic fluid leaks and loss of system pressure. On a refuse and landfill compactor like the BC 601 RB — where hydraulic systems power the compaction wheel drives and steering under constant heavy load — a failed back-up ring can quickly escalate into significant hydraulic damage and unplanned downtime.
