Mechanical hardware
The parts nobody puts on a slide and every machine depends on. Mechanical hardware is bought on availability and interchangeability far more than on price, which makes it an unusually good business for a supplier with a US shelf and a clear cross-reference.
15 shelves
we want filled.
Every line below is a display we would like somebody to own. Several are still completely open.
- 01
Bearings
Deep-groove, angular contact, crossed-roller, thin-section and ceramic hybrids. Noise class, preload and the lubricant you ship with are the specifications that decide a robot joint.
- 02
Linear motion components
Rails, carriages, shafts, bushings, telescopic slides and support blocks. Interchangeable geometry sells here: a dimensional drop-in wins designs a better load rating alone will not.
- 03
Fasteners
Socket screws, shoulder bolts, threaded inserts, rivet nuts, self-clinching hardware and captive fasteners, with material grade and plating specified rather than assumed.
- 04
Springs and dampers
Compression, extension, torsion and wave springs, gas springs, rubber mounts and vibration isolators. Fatigue data at the customer's stroke, not at a convenient one.
- 05
Seals and gaskets
O-rings, rotary shaft seals, gaskets, cord stock and custom mouldings. Media compatibility and the temperature range are the whole conversation, and both are often overstated.
- 06
Gears and gearing
Spur, helical, bevel, worm and rack gearing, ground and hobbed, with the quality grade stated. Custom gear cutting is a service worth advertising as loudly as a catalogue.
- 07
Castors, wheels and mounts
Industrial castors, drive and idler wheels, levelling feet and machine mounts. Boring, high-volume, and specified on the last day of every project.
- 08
Shafts, couplings and collars
Ground shafts, keyed and keyless shaft-hub connections, locking assemblies, shaft collars and clamping elements. Concentricity after clamping is what buyers measure.
- 09
Aluminium extrusion and framing
Profile systems, connectors, panels, doors and prebuilt assemblies. Compatibility with the common slot standards is worth stating in the first line of your listing.
- 10
Enclosures and cabinets
Sheet-metal and die-cast enclosures, control cabinets, junction boxes, racks and the climate control and sealing that go with them.
- 11
Cable management
Drag chains, cable carriers, strain reliefs, spiral wrap, glands and rotary unions. Where integration surprises live, and where a million-cycle machine quietly fails.
- 12
Pipes, fittings and fluid handling
Tubing, hose, quick couplings, manifolds, pumps and small valves for coolant, air and process fluid. Burst pressure at temperature and the fitting standard you follow.
- 13
Magnets and magnetic assemblies
Neodymium and ferrite magnets, magnetic couplings, holding assemblies, electropermanent units and magnetic shielding. Grade, coating and demagnetisation curve, published.
- 14
Hinges, latches and access hardware
Hinges, latches, handles, gas struts, panel locks and the small hardware that decides whether a machine can be serviced in the field.
- 15
Wear parts and tribology
Bushings, wear strips, plain bearings, coatings and dry-running polymer parts. The category that determines maintenance interval more than any other.
How to stand out
in this category.
A cross-reference table against the incumbent brands is the single most useful document you can bring to this floor. Tolerance class, material certificate and surface treatment should be on the same page as the part number.
