The Bomag 05660360 Tension Spring is a genuine OEM component designed for Bomag BW-series tandem rollers and BM-series cold milling machines. Sourced directly from Bomag, this tension spring meets the original engineering specifications your equipment was built around. It is confirmed to fit the BW 100 AC-3, BW 120 AC-3, BW 135 AC, BW 138 AC, BW 100 AC-4, BW 120 AC-4, BW 125 AC-4 tandem rollers, as well as BM 500/15, BM 600/15, and their variant models including EU-Flex, Stage V, T4i, and second-generation configurations. When a tension spring wears or breaks, restoring it with the correct OEM part keeps the affected system operating as Bomag intended.
Key Features
- Genuine OEM Spring Grade — manufactured to Bomag's original load and elasticity specifications, ensuring the correct tension range for the application rather than an approximated replacement
- Direct Drop-In Fit — hooks, coil diameter, and free length match the original mounting points so this tension spring installs without modification
- Broad Model Coverage — fits BW 100 AC-3, BW 120 AC-3, BW 135 AC, BW 138 AC, BW 100 AC-4, BW 120 AC-4, BW 125 AC-4 tandem rollers, and BM 500/15 and BM 600/15 cold milling machines across multiple emission-tier variants
- Consistent Mechanical Tension — a properly rated spring maintains the designed preload on the connected component; a fatigued or broken spring can cause slippage, misalignment, or loss of function in the system it controls
- Verified Part Number — ordering by Bomag part number 05660360 confirms you are receiving the correct spring for your specific machine, eliminating guesswork during service
A tension spring stores and releases mechanical energy to hold components under a consistent pulling force within the assembly. In compaction and milling equipment, tension springs are commonly used to maintain belt tension, return actuator arms, or preload linkages — ensuring that moving parts return to their correct neutral or engaged position after each cycle. When a tension spring loses its rated load capacity through fatigue or breaks entirely, the component it controls may not return properly, causing inconsistent operation, premature wear on surrounding parts, or a complete loss of the function it governs.
