Profab Machine manufactures stainless steel rod ends, also called heim joints, and spherical bearings in 304, 316/316L, and 17-4PH, plus custom CNC parts built to your drawings. From rapid prototypes to volume production, we make the parts that keep marine and food-processing equipment moving.
Since 2005, Profab Machine has built corrosion-resistant stainless steel components, led by rod ends and spherical bearings. Our CNC production lines, 5-axis machining, and welding, electropolishing, and passivation services cover the machining, joining, and finishing of your parts, and you deal directly with the factory.
OEMs and equipment builders in automotive, industrial, marine, and medical sectors order from us, from rapid prototypes to volume production. Every order gets in-process and final inspection before it ships. See how we check every order, or read more about us.

Marine and food processing are where we are strongest, and the same parts serve the industries below.
316L hardware for vessels, docks, and offshore structures. Cleats, shackles, handrails, propellers, and custom fittings built to resist salt spray and constant flexing.
Explore marine parts →Food-grade 316L parts for washdown and hygienic environments. Sanitary valves, spray balls, roller conveyors, and custom food-grade assemblies that stand up to CIP cleaning.
Explore food processing parts →
Rod ends, clevis, wheel spacers, and suspension hardware.
Pulleys, sprockets, chain, and precision structural parts.
Ground support equipment, test rigs, and MRO tooling.
Beds, lifts, lab platforms, and mobility frames.
Racking and tracker parts for salt, heat, and movement.
We also supply stainless steel raw materials alongside finished components.
Round, hex, and flat bar in 303, 304, 316L, and 17-4PH. Cut to length.
Seamless and welded tube, OD 6–200 mm, Schedule 5S to 80S.
2B, BA, and No. 4 finish, thickness 1–50 mm. Material test certificates are available on request.
Precision ground rod for CNC input material, OD tolerance h6/h8.
General-purpose grade with good corrosion resistance in mildly corrosive environments. Our most ordered material.
18/8 AusteniticMolybdenum-alloyed grade for marine, chemical, and food environments. Standard for anything exposed to saltwater.
Marine Grade · Food SafePrecipitation-hardened grade. Tensile strength reaches about 1,310 MPa after H900 heat treatment, for high-load linkages.
Precipitation HardenedDual austenitic-ferritic structure with higher strength than 316L and strong resistance to chloride stress corrosion.
Offshore · ChemicalSend details, a drawing, or a sample part. Photos work too. We confirm the material and finish.
We work out the best solution for your request and send you a specific quote within 24 hours.
Engineers review each drawing for manufacturability. Parts ship by sea, air, or freight.
We source rod ends and clevis for suspension components. Profab's tolerances are tight and the material certs are legit. We verified them with our own XRF gun on the first order. Now on our fourth order and no issues.
We needed to upgrade the material grade on a linkage. Profab reviewed the specs, recommended a better alloy option, and the final parts performed exactly as expected in our environment. They clearly understand materials and industrial applications. Good factory.
Marine hardware for our charter fleet. Everything in 316L, mirror finish where visible. The cleats and turnbuckles have been in saltwater service for two seasons now, with no pitting and no discolouration. Worth the price.

There is no hard minimum. We regularly run prototypes of 100 pieces and full production runs of 10,000+. Pricing tiers at 100, 500, and 1000 pieces. We show all tiers in our quotes so you can see where the economics shift.
We regularly machine 303, 304, 304L, 316, 316L, 17-4PH, 2205 duplex, 2507 super duplex, 410, and 430. If you need a grade not listed, just contact our team.
Yes. Send DXF, DWG, STEP, IGES, or PDF with dimensions. If you only have a sample part and no drawing, we can reverse-engineer it for an additional fee. We review all drawings for manufacturability before quoting.
304 is the go-to for indoor and mildly corrosive environments. It is cheaper and machines easily. 316 adds molybdenum, which resists chloride attack, so use it for anything exposed to saltwater, coastal air, food-grade cleaning chemicals, or marine environments. The cost difference is typically 15–25%.
Electropolishing, sandblasting and bead blasting, mirror polishing, powder coating, passivation, brushing (satin finish), and black oxide (on stainless steel alloys that support it).
