Crusher Wear Parts
Stedman Blow Bars
Replacement bars for Stedman and comparable North American impactor designs, supplied as weight-matched sets.
Overview
About stedman blow bars
Melco supplies replacement blow bars for Stedman impactors and for the comparable Eagle, Metso and Astec designs that share similar rotor arrangements. These are long-standing export lines for us, shipped in container quantities to North America.
Bars are cast to the customer drawing or reverse-engineered from a sample, then heat treated to the grade appropriate for the duty. Because these machines often run mixed recycling feed as well as virgin rock, we frequently supply the same profile in more than one alloy.
Every set is weighed and matched, and the mounting geometry is checked against the drawing so the bar seats square in the rotor pocket.
Applications
- Stedman, Eagle, Metso and Astec impact crushers
- Aggregate and hard rock crushing
- Recycled concrete and asphalt
- Industrial minerals and lime processing
Features
What you get
Multiple alloys per profile
The same bar in high chrome, martensitic or manganese steel to suit changing feed.
Checked mounting geometry
Pocket faces verified against drawing so the bar seats square and the rotor runs true.
Export packing as standard
Bars strapped to heat-treated timber pallets, marked and documented for sea freight.

Questions
Stedman Blow Bars: common questions
Which machines do these bars fit?
We produce bars for Stedman impactors and for comparable Eagle, Metso and Astec rotors. Send the machine model and either a drawing or a sample bar and we will confirm before quoting.
How are the bars packed for export?
Bars are strapped to ISPM-15 heat-treated timber pallets, edge-protected and marked with the part number and heat number. Container loading plans are provided with the shipping documents.
What lead time should I plan for?
Where a pattern already exists, production plus sea freight is the main driver. For a new pattern, add the pattern shop time. We give a firm date with the quotation rather than a general estimate.
Are these OEM Stedman parts?
No. These are independently manufactured replacement wear parts intended to fit Stedman machines. Melco Castings is not affiliated with or endorsed by Stedman, Eagle, Metso or Astec.
