Conversion
Symmco specializes in powder metal part conversions since no company should waste precious time, money and resources when higher precision parts can be produced at a lower cost through the powder metal process.
From the smallest of bearings to the largest of complex structural components, Symmco has the engineering expertise and production capacity (press sizes ranging from 5 to 750 tons) to manufacture a wide range of high-quality powder metal products that can save you money.

Quality
Additionally, Symmco participates in the conflict-free sourcing initiative (CFSI) and, subsequently, is a conflict-free minerals manufacturer.

Beyond bushings
Complex structural parts, pressed on the same floor as the bearings
Engineers tend to know Symmco for sintered bronze bearings, and the catalogue reinforces that, so the gears, sprockets, levers, clutch and actuator components and complete assemblies that come off the same press floor are easy to miss. The two helical gear conversions on the conversions page are typical of that work: a machined blank that yielded over 50% scrap became a near-net-shape powder metal gear, and a gear pair that had started life as expensive fully machined pieces was molded for exactly its intended use.
The equipment behind that range is 39 compacting presses across the Pennsylvania and Tennessee plants, from 5 to 750 tons, with Dorst presses at both plants and Osterwalder presses in Pennsylvania producing parts with up to seven levels. Parts run from 0.050 inch in outside diameter and overall length up to 6.00 by 12.00 by 1.00 inches, weight is not a constraint, and sizing tolerances can be held as tight as 0.001 inch.
Symmco runs the majority of MPIF Standard 35 materials across bronze, iron-copper, iron, steel and stainless steel, and also presses soft magnetic composites. It does not manufacture parts that require high-temperature sintering, and its engineers raise that at quoting so alternatives can be discussed.
| Plant | Presses | Tonnage | Drives | Multi-level |
|---|---|---|---|---|
| Sykesville, Pennsylvania | 36 | 5 to 750 tons | Mechanical, hydraulic and electric | Dorst and Osterwalder presses, up to 7 levels |
| Surgoinsville, Tennessee | 3 | 300 to 500 tons | Electric and hydraulic | Dorst presses, up to 7 levels |
| Capability | Figure |
|---|---|
| Compacting presses | 39 across the two plants, from 5 to 750 tons |
| Press levels | Up to 7, on Dorst and Osterwalder presses |
| Smallest part | 0.050" outside diameter, 0.050" overall length |
| Largest part | 6.00" wide, 12.00" long, 1.00" thick |
| Part weight | Not a constraint; it follows from density and size |
| Sizing tolerance | As tight as 0.001" |
| Materials | The majority of MPIF Standard 35 grades across bronze, iron-copper, iron, steel and stainless steel, plus soft magnetic composites |
Commercial terms
Why buyers move bushing and bearing programs to Symmco
A bearing program usually moves for a commercial reason before a technical one, so the terms that decide it are set out here rather than left to the quote, and the ones that concern stock sizes apply to the catalogue exactly as published.
No tooling charge, and no minimum on stock sizes
Symmco does not charge tooling costs on any standard tooling product, and there is no minimum order quantity on the stocked parts in its catalogue, which today means over 1,500 unique stocked parts backed by tooling for more than 5,000 standard sizes. Custom parts carry no minimum quantity either; the only floor is a $1,000 minimum manufacturing cost on non-stock work.
Stock that ships in 24 hours
Stocked parts ship in 24 hours, drawn from the largest inventory of sintered bronze bushings and bearings in North America at a 99% fill rate on stock products, and Symmco supplies parts directly to distributors as well.
Tooling you own, maintained at Symmco's expense
When an order requires custom tooling, the customer owns it. Once that original set of tools has been purchased, Symmco maintains all of it and replaces any broken tools at its own expense, and a buyer who already owns tooling from a previous supplier can transfer it to Symmco for quicker production.
Open capacity
Symmco has more than enough open capacity for new product opportunities, bushings are always being manufactured, and it will not turn down an order because of a capacity constraint.
What a switch looks like
Customers have transferred their tooling to Symmco, or launched new products there, for many reasons, and what they get is the same in each case: direct quality and technical support through development, engagement with what the end user actually needs, and a company that works with them toward the best ship date possible.
Where to start
Three ways in, depending on whether you are holding a part number, a drawing, or a question about terms.
Find a part
Search the twelve stock families by part number or dimensions, with 2D drawings and interchange part numbers, then request a quote on the size you need.
GoRequest a quote
Send a drawing or a part number for custom or non-stock work. Bearing quotes turn around in one day and structural quotes in under a week.
GoTooling and terms
Who owns the tooling, what it costs on a stock size (nothing), how long it takes to arrive, and where the minimums sit.
