Plain & flanged bushings
Cylindrical bearing interfaces where bore size, wall section, load, lubrication and wear drive the specification.
PM is strongest when the component geometry, compaction direction, density, load, wear, critical interfaces and repeat-volume economics support press-and-sinter production.
This family covers bearing sleeves, flanged bushings and compact structural parts where powder compaction, sintering, sizing and selective secondary operations can reduce material waste and machining time at repeat volume.
Cylindrical bearing interfaces where bore size, wall section, load, lubrication and wear drive the specification.
PM parts can be sized after sintering when dimensional repeatability on a bore or outside diameter is important, subject to part geometry and specification.
Hubs, blocks, carriers and compact functional shapes that can be pressed along a practical compaction direction.
Near-net-shape PM blanks can keep the bulk geometry economical while machining only threads, cross-holes, sealing faces or precision datums.
| Part condition | PM fit | What to review |
|---|---|---|
| Simple bushing / sleeve | Often a strong PM screening candidate at repeat volume. | Bore/OD, wall thickness, flange features, load, wear, lubrication and any sizing requirement. |
| Press-friendly structural part | Strong when major features align with compaction direction. | Tool access, density distribution, ejection, unsupported thin sections and transverse features. |
| Cross-holes / undercuts / complex 3D features | May need machining, special tooling, MIM or another route. | Do not force conventional PM if secondary operations or tooling complexity remove the economic benefit. |
| High precision on selected surfaces | PM blank + sizing/machining/grinding may be appropriate. | Identify only the interfaces that truly require tighter control. |
| Low-volume prototype | Direct machining may be more practical. | Tooling economics and qualification cost should be weighed against projected program life. |
Required density and mechanical performance depend on material, geometry, compaction, sintering and load. SINTS reviews these requirements against your drawing and application.
These are direct component-family references from the current SINTS product library. Their geometry supports the PM manufacturing discussion without implying a specific customer or end-use program.

SINTS PM referenceDefine mating shaft size, clearance, surface expectation and whether post-sinter sizing or machining is allowed.
Dry running, external lubrication, contaminants, corrosion and temperature change the right material and finish strategy.
Cross-holes, side slots and threads can add secondary operations. Their cost should be included before tooling is approved.
Steps, thin walls and large area changes affect tooling, density and ejection. Early DFM can simplify the part before the die is built.
Drive and pivot support interfaces exposed to dust, moisture and repeated duty.
Application guide →Pivot and gearbox support bushings where wear and clearance affect mechanism feel.
Application guide →Bearing or locating-adjacent components where fit and cycle life matter.
Application guide →Bushings and drive-support parts where wear, filler abrasion and chemical exposure may matter.
Application guide →The retained bushing detail page focuses on bore/OD, load, lubrication, wear, sizing and secondary-machining decisions for sleeve and flanged forms.
For bushings, include mating shaft, bore/OD requirements, load, lubrication and wear expectations. For structural PM parts, identify critical datums, transverse features, material, annual demand and any machining or heat treatment.
