MTW 9W7043-50 DBF Cutting Edge: 50×330×1788mm Heavy Duty Wear Part at 220.2KG

MTW 9W7043-50 DBF Cutting Edge: Big Iron Deserves a Blade Built to Match
When the machine is large, the blade has to be large too — and it has to be right. MTW WEAR PARTS (SUZHOU) CO., LTD supplies the 9W7043-50 DBF Cutting Edge, a heavy-duty replacement wear part measuring 50×330×1788mm with a unit weight of 220.2KG. It is built for compatible ground-engaging equipment where a thick, wide and long cutting component is required, and it is dimensioned to OEM reference 9W7043-50 so buyers can verify fit before committing to an order.
Why the Large Format Matters
A 50 mm section paired with a 330 mm width and an 1788 mm length means more wear material in the cutting zone and fewer change-outs across a working season. For fleet managers, that translates into less wrench time, fewer lifting operations and a more stable cutting edge under continuous load. The DBF (Double Bevel Flat) profile keeps the cutting geometry flat and consistent, so the blade tracks cleanly through soil and spoil instead of digging in unevenly.
That combination — thick section, extended length and a flat double-bevel edge — is what makes this part suitable for earthmoving and excavation, soil scraping and material handling, construction site preparation and general ground-engaging work.

Choosing the Steel Grade
Steel choice decides whether a blade wears evenly or fails early. MTW offers the 9W7043-50 in two grades:
- Boron steel MTW500 — through-hardening grade that retains hardness deep into a thick section, well suited to abrasive, high-impact digging where the full 50 mm of material needs to work.
- Manganese steel MTW400 — work-hardening grade that deforms and hardens under impact, a practical choice where shock loading and crack resistance are the priority.
Both are supplied in standard yellow, with custom colours available for fleet identification and dealer branding.
Logistics for a 220.2KG Component
Heavy parts need heavy-duty planning. Each unit weighs 220.2KG, so handling, palletisation and container loading all affect landed cost. MTW ships on plywood pallets suitable for container loading and long-sea transit, with a minimum order quantity of 5000 KGS and a typical delivery time of 6–8 weeks. For distributors building stock programmes, we can advise on mixed pallet configurations and loading plans.
Manufacturing Backing
Founded in 2011, MTW is a dedicated wear parts manufacturer with a team of roughly 100–300 people producing cutting edges, bucket wear parts and ground-engaging components. Output is 90%–100% for export markets, and every part is identified by part number, blade profile, dimensions and weight, so customers can confirm suitability before shipment.
Frequently Asked Questions
