Bomag 05801868 Spring Cup

The Bomag 05801868 Spring Cup is a genuine OEM component designed for a wide range of Bomag single drum rollers, tandem rollers, refuse/landfill compactors, cold milling machines, recyclers/stabilizers, and soil compactors. As a direct factory replacement, this spring cup delivers the correct geometry and material grade needed to seat and retain springs precisely as the original design requires. Compatible models include BW-series rollers such as the BW 100 AD-5, BW 120 AD-5, BW 174 AP-4, and BW 202 AD-4, BC-series refuse/landfill compactors including the BC 601 RB, BC 772 RB, BC 972 RB, and BC 1172 RB, cold milling machines BM1200/30 and BM1300/30, and MPH-series recyclers/stabilizers including the MPH 121, MPH 122, and MPH 125, among many others. Sourcing this part directly from an authorized Bomag OEM supplier ensures the correct fit across all listed applications without guesswork.

Key Features

• Genuine OEM Material Grade — manufactured to Bomag's original spring cup specification, ensuring correct seating depth, wall thickness, and hardness for consistent spring retention under load
• Drop-In Replacement — matches the original mounting profile exactly, allowing this spring cup to seat into position the same way as the factory part with no rework to surrounding components
• Broad Cross-Family Coverage — fits single drum rollers, tandem rollers, refuse/landfill compactors, soil compactors, cold milling machines, and recyclers/stabilizers across Bomag's BW, BC, BM, and MPH families, including models such as the BW 174 AP-4, BC 1172 RB, BM1300/30, and MPH 125
• Consistent Spring Load Retention — a correctly fitted spring cup maintains proper spring preload and alignment; a worn or deformed cup allows the spring to shift off-axis, accelerating wear on adjacent components and degrading damping or tensioning performance
• OEM Part Number Confidence — supplied under Bomag part number 05801868, so technicians and parts managers can cross-reference against service documentation with confidence

A spring cup is a recessed or flanged seat that locates and retains a coil spring, keeping it centered and preventing lateral movement under compression. In heavy compaction and milling equipment, spring cups appear in vibration isolation mounts, tensioning assemblies, and other load-bearing spring arrangements where precise spring alignment directly affects how force is transmitted or absorbed. When a spring cup cracks, deforms, or wears through, the spring it supports can shift position, resulting in uneven load distribution, increased vibration, accelerated wear on surrounding hardware, and potential loss of the function the spring assembly is meant to provide.
