BOMAG Rubber Part Number System Overview
BOMAG uses a structured part numbering system for rubber isolation and cab mounting components. Understanding this system allows procurement managers, maintenance technicians, and parts specialists to identify, cross-reference, and order the correct replacement rubber parts for BOMAG BW series compactors and scrapers.
Rubber components appear primarily in the 3115 XXXX XX and 3128 XXXX XX number ranges, with some older OEM references in short numeric formats (e.g., 354082, 450122, 801187). This guide decodes all of these systems.
The BOMAG 3115 Series — Vibration and Isolation Components
The 3115 prefix identifies BOMAG vibration isolation and damper components. These parts are primarily used in the vibration transmission path between the drum exciter system, the machine frame, and the operator environment.
Key 3115 series parts and their functions:
- 3115 1822 00 — Primary cab mount rubber buffer; found at cab-to-frame mounting positions on BW 177–226 series
- 3115 1822 01 — Cab isolation mount type-1; variant with different geometry/stiffness from 3115 1822 00
- 3115 1926 02 — Vibration damper rubber; used in drum vibration isolation system
- 3115 2472 00 — Anti-vibration mount; primary vibration isolation element for compactor frame
- 3115 9150 99 — Rubber buffer element; travel end stop and limit buffer
The XXXX portion of the 3115 number identifies the specific component design within the sub-category. The final two digits (XX) typically indicate a design variant or revision level. When ordering, always specify the full 10-digit part number including all spaces.
The BOMAG 3128 Series — Cab Mounting Assemblies
The 3128 prefix identifies BOMAG cab mounting rubber components. These are the primary NVH isolation components between the BOMAG compactor cab and the machine frame.
Key 3128 series parts:
- 3128 0458 15 — Cab mount, 15 Shore A (soft)
- 3128 0458 18 — Cab mount, 18 Shore A (medium) — most common
- 3128 0458 24 — Cab mount, 24 Shore A (firm)
- 3128 3175 50 — Cab suspension element; spring-type isolation component
- 3128047510 — Rubber isolator; used in secondary isolation locations
- 3128259405 — Cab mount assembly; complete unit with metal hardware
- 3128303930 — Rubber buffer block; impact absorption at structural end stops
Understanding Shore A Hardness Codes in BOMAG Part Numbers
Shore A is the standard hardness scale for soft rubber, ranging from 0 (very soft) to 100 (very hard). For BOMAG cab mounts, the relevant range is 15–40 Shore A, with most applications falling between 15 and 24.
In the 3128 0458 series, the final two digits directly indicate Shore A hardness:
- 15 → 15 Shore A — Softest, highest vibration isolation, least load capacity
- 18 → 18 Shore A — Balanced isolation and load capacity — MOST COMMON
- 24 → 24 Shore A — Firmest, lower vibration isolation, highest load capacity
Critical Warning
Installing the wrong Shore A hardness doubles or triples vibration transmission to the operator. Always verify the correct hardness from the BOMAG service manual for your specific BW model number before ordering.
For equipment models where the correct hardness is unknown, our technical team can advise based on BW model number, serial number range, and operating conditions. Contact us for technical assistance.
BOMAG Part Numbers: Cross-Reference to Other Brands
While BOMAG uses its own part number system, many cab mount rubber elements used in BOMAG equipment share dimensional characteristics with components from other heavy equipment brands. Our cross-reference database identifies these equivalents:
- BOMAG 3115 1822 00 ↔ Several CAT and Komatsu cab mount dimensions overlap
- Part numbers 1487116, 1524771, and 6180100 serve as cross-references for multiple platforms
- OEM numbers 20891618, 20891878, 20891908 are used across multiple compactor brands
Cross-referencing requires dimensional verification — not just part number matching. Our engineering team performs dimensional cross-reference verification for all supplied parts.
How to Order BOMAG Rubber Parts — What Information to Provide
To ensure you receive the correct BOMAG rubber parts, provide the following information when placing an order:
- Full BOMAG part number — include all spaces and digits (e.g., 3128 0458 18, not 312804581)
- BOMAG machine model — e.g., BW 211 D-40, BW 226 D-5
- Machine serial number — to confirm production year and correct variant
- Quantity required — cab mounts are sold individually; full set is typically 4–6 units
- Delivery destination — US state/city for accurate freight cost and lead time
- Documentation requirements — CoC, material test reports, EN 45545-2 if needed
