The Bomag 05870221 Right Crawler System is a genuine OEM component designed for the BM 1200/30 and BM 1300/30 cold milling machines. Sourced directly from Bomag, this assembly delivers the exact fit and construction required to keep these heavy-duty cold mills tracking and operating at full capacity. This crawler system is the right-hand assembly, engineered to match the original specification of the BM 1200/30 and BM 1300/30 precisely. When it comes to a critical undercarriage component, genuine OEM quality is the standard that matters most on a production job site.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original design specifications, ensuring the crawler assembly meets the structural and load-bearing demands of production cold milling operations
- Right-Hand Assembly — this is the right-side crawler system, supplied as a complete assembly for direct installation on the correct side of the machine — no cross-fitting or adaptation needed
- Confirmed Fitment — verified for the BM 1200/30 and BM 1300/30 cold milling machines, so you can order with confidence knowing this is the correct replacement
- Restored Undercarriage Performance — a worn or damaged crawler system compromises traction, tracking stability, and cutting pass control; replacing it restores full drive performance and milling accuracy
- Operational Safety — the crawler system is a primary drive and ground-contact component; using a properly specified OEM replacement reduces the risk of unexpected undercarriage failure during high-load milling passes
The crawler system is the undercarriage drive assembly that propels the cold milling machine across the work surface while supporting the machine's full operating weight. On cold milling machines like the BM 1200/30 and BM 1300/30, the crawler tracks must maintain consistent traction and straight-line tracking to achieve accurate milling depth and a uniform cut. When a crawler system wears or sustains damage, the machine can drift, lose ground contact stability, or fail to advance evenly — all of which directly affect cut quality, operator control, and overall productivity on the job.
