Triangle Machine Products is a reliable manufacturer of unthreaded and threadless bushings, delivering precision-machined components for use in mechanical, structural, and motion-critical applications. Designed to serve as alignment guides, load distribution surfaces, or wear-resistant interfaces, our bushings are custom-machined for performance where it matters most.
Because they lack threads, unthreaded bushings rely entirely on their geometry, surface finish, and material characteristics to perform effectively. That’s why we machine each part to exacting tolerances—ensuring a consistent press fit, slip fit, or precision clearance, depending on the assembly requirements. Triangle’s bushings are designed to integrate seamlessly into your equipment, not compromise it.
Unthreaded bushings are commonly used to locate shafts, reduce friction, isolate components, and prevent wear in a wide range of industrial assemblies. Their simplicity in design is matched by their importance in function. Whether acting as a spacer, sleeve, or guide, these parts require careful attention to internal diameter, wall thickness, and overall geometry to maintain alignment and performance over time.
At Triangle, we machine unthreaded bushings with the same focus we bring to complex components: controlled tolerances, clean surfaces, and consistent material properties. Our bushings are used in equipment where motion must remain smooth, repeatable, and within precise mechanical boundaries—including hydraulic housings, mechanical linkages, rotating assemblies, and alignment jigs. We work with a range of fit types and bushing styles, from slip-fit sleeves to press-fit liners, each made to suit your specific mechanical interface.
When off-the-shelf sleeves don’t meet the mark, Triangle Machine Products provides custom threadless bushings machined to your exact dimensions. Whether you need a custom internal bore, non-standard length, split bushing design, or chamfered ends for press-fit installation, we manufacture each part based on your engineering drawings or modeled designs.
We accommodate single-feature bushings as well as more complex forms with stepped diameters, flanges, shoulders, or integrated features for secondary positioning or retention. All bushings are machined from high-integrity bar stock using CNC turning and inspection processes designed for tight concentricity and repeatability. Whether for a short-run tool or a high-volume OEM assembly, our unthreaded bushings are built to your requirements and application environment.
When your assembly depends on precise motion, a bushing is not just a passive part—it’s a wear surface, a guide, and a support. At Triangle Machine Products, we understand how dimensional variation, surface finish inconsistency, or poor material selection can lead to binding, misalignment, or early failure. That’s why we machine every bushing with care, holding tolerances that mass-formed or sintered parts often can’t match.
We offer a wide range of material options—from carbon and alloy steels to stainless, aluminum, and brass—tailored to your load, lubrication, and environmental needs. Our manufacturing process allows for consistent repeatability across production batches, with real-time inspection and quality verification throughout. Whether you need one prototype or thousands of production parts, Triangle delivers unthreaded bushings that meet your specs and perform under pressure.
An unthreaded (or threadless) bushing is a smooth, cylindrical component used to locate, guide, or isolate parts in mechanical assemblies. Common applications include press-fit liners, rotating shaft guides, and spacers in load-bearing or motion-sensitive systems.
Yes. We specialize in custom unthreaded bushings with unique internal diameters, wall thicknesses, flanges, chamfers, or step features—all machined to fit specific tolerances and performance needs.
We offer a variety of materials including carbon steel, stainless steel, brass, aluminum, and specialty alloys. Material selection is based on application factors such as load, temperature, wear resistance, and environmental exposure.
