Hongjie Sealing Technology molds custom rubber bushings — including rubber-to-metal bonded sleeves — that sit between two mating or moving parts to isolate vibration, absorb shock, and cut mechanical noise. Send a drawing or sample and our engineers quote tooling, material, and bonded-construction options for your assembly.
A rubber bushing decouples metal-to-metal contact, letting the elastomer flex and absorb energy instead of the surrounding hardware. We produce these as anti vibration rubber bushings by injection molding and compression molding.
A bonded metal core (steel or aluminum vulcanized to the rubber) carries higher radial/axial load and won't walk out of its bore, but costs more to tool. A press-fit rubber sleeve is cheaper and easier to service, but relies on interference fit alone, so it suits lighter loads. We quote both and recommend one based on your load case.
Motor mounts, pump isolators, panel dampers
Suspension bushings, mount inserts, linkage isolators
Compressor and motor vibration isolation
Sleeve isolation around pipes, rods, and fasteners
A bushing is often part of a larger assembly. For wiring through the same panel, see custom wire-harness grommets. For a flat sealing disc in the fastener stack, see custom rubber washers and sealing discs.
Bore, OD, length, and wall thickness are molded to your drawing across a 0–100mm dimensional range, with tighter or larger geometries quoted case by case.
| Dimension Range | Standard | Precision |
|---|---|---|
| 0–10mm | ±0.10mm | ±0.02mm |
| 10–25mm | ±0.15mm | ±0.05mm |
| 25–50mm | ±0.20mm | ±0.08mm |
| 50–100mm | ±0.25mm | ±0.10mm |
| Material | Typical Use | Bonded / Unbonded |
|---|---|---|
| NBR | Oil-exposed mounts, hydraulic bushings | Bonded or unbonded |
| EPDM | Outdoor/weather-exposed isolators | Bonded or unbonded |
| Neoprene (CR) | General-purpose vibration mounts | Bonded or unbonded |
| Silicone (VMQ) | Appliance and medical-adjacent isolation | Unbonded |
| Polyurethane (AU/EU) | High-load, abrasion-heavy suspension bushings | Unbonded (press-fit) |
| HNBR | Higher-temperature automotive bushings | Bonded |
Hongjie has manufactured rubber components since 2001 from an 11,000 m² Shenzhen facility with roughly 150 staff, certified to IATF 16949:2016 and ISO13485:2016. We hold 3,500+ existing tools, work with FDA and NSF compliant compounds, and turn functional prototypes in 3–5 business days so you can validate a bushing design before production tooling.
Include quantity, durometer, load case, bore fit (press-fit or bonded-core), and material/temperature preference. Upload your drawing — STEP, IGES, or a physical sample — for an OEM quote. Contact our engineers to start your custom rubber bushing project.
