M6 M8 M10 Vibration Mounts DD Type Female To Female Silent Rubber Isolator Mounts
Product Details
M8 vibration mounts
,M10 vibration mounts DD Type
,Female rubber isolator mounts
DD-type anti-vibration mounts are moulded from natural rubber bonded to white galvanised steel, forming a compact female-to-female silent block that isolates small machinery from floors and frames. Threaded inserts at both ends make them easy to fit wherever a stud fixing is required.

- Operating temperature range of −40 °C to +80 °C
- Suited to machinery running above 1200 rpm
- Metal-to-rubber adhesion strength of about 40 kg per square centimetre
- Made from ROHS-compliant natural rubber with no reclaimed material
- High-strength grade 8.8 fixing screws
- Metal plating passes a 96-hour salt-spray test
- Anti-ageing, heat-resistant, wear-resistant compound
- Produced on imported equipment with strict quality control
Standard shock absorbers are typically used for fixed or elastic fastener equipment. Suitable for various applications, particularly elastic suspension and vibration isolation of machines and various machinery, including:
- Small motors, water pumps and fans
- Dryers and light blowers
- Electric motors and measuring equipment
- Centrifugal industrial fans
Complete specifications from 8 mm to 150 mm outer diameter size to meet various industrial needs.
Choose the right DD rubber shock absorber to meet specific industrial needs:
- Load bearing capacity: Size the mount to the equipment weight so it carries both static and dynamic loads.
- Material selection: Match rubber grade to the environment, allowing for oil, temperature and chemical exposure.
- Size and shape: Check overall dimensions against the installation point for effective isolation.
- Hardness: Softer compounds damp better but wear faster, so balance comfort against durability.
- Working environment: Allow for ambient temperature, humidity and chemical contact when choosing the compound.
- Installation and maintenance: Choose easy-to-service mounts to keep downtime and maintenance costs low.
- Performance parameters: Align static compression, natural frequency and dynamic stiffness with the running speed.

Female-to-female threaded silent blocks like this DD type come from Shanghai Songjiang Jiufu Shock Absorber Co., Ltd., a plant that has been moulding rubber onto metal inserts since 2003. The factory occupies a site in Songjiang District, Shanghai and employs somewhere between fifty and a hundred people across mixing, moulding, finishing and quality functions.
For a threaded silent block the critical detail is the insert: thread class, depth and concentricity decide how the mount sits on a machine frame. That work is done in house here, which is how M6, M8 and M10 variants can be quoted from the same drawing family instead of being sourced separately.
Metal components are white galvanised or plated to survive a 96 hour salt spray test, and the rubber-to-metal bond is engineered to reach 40 kg/cm2 of adhesive strength. For a threaded silent block that combination is what prevents the insert from working loose in a vibrating machine frame. Custom hardness, thread size, plating and packaging are all produced to order rather than drawn from a fixed list.
| Key facts | Details |
|---|---|
| Year of establishment | 2003 |
| Business model | Direct manufacturer, OEM and ODM supported |
| Where | Songjiang District, Shanghai, China |

| Sequence | Description |
|---|---|
| Compound preparation | Natural or synthetic rubber mixed to the hardness and resistance class the application demands, typically 30 to 90 Shore A |
| Insert machining and treatment | Threaded steel inserts machined, blasted, phosphated and primed for bonding |
| Mould charging | Inserts located in the cavity, rubber pre-form placed, mould closed |
| Vulcanisation | Heat and pressure applied for the full cure cycle so the rubber locks onto the insert |
| Deflashing | Excess rubber removed mechanically and by hand, threads re-cleared |
| Inspection | Hardness, thread gauge, height and deflection measured against the drawing |
| Packing | Counted into cartons with batch references for later traceability |
The quality system is certified to ISO 9001. Compounds comply with RoHS and REACH, with the declaration supplied on request, and third-party testing through an accredited laboratory is available for buyers who require it. In-house capability spans hardness measurement, load-deflection testing, oil resistance and accelerated ageing, so batch-to-batch variation is caught at the source.
Need a different thread, hardness or insert plating? Those parameters are made to order rather than fixed.
Current ISO certificates and the RoHS certificate of conformity are on file at the plant. The scans below can be matched against the certificate numbers quoted in any tender or vendor registration pack.

Additional Notes
Field notes for the M6 M8 M10 DD Type Rubber Vibration Mount Female to Female Silent Block Anti Vibration Mount: installation is simply bolting down and levelling, but the result depends on matching the mount to the load. A few minutes confirming the point load saves hours of re-work later.
- Suited to equipment running above 1200 rpm, where plain pads fall short.
- Galvanised steel hardware keeps thread strength high through repeated maintenance.
- Load capacity is rated against the actual dynamic load, not just the static weight.
In practice the mount is chosen so that, once loaded, it still has travel left to absorb movement. A mount that is already compressed solid at rest gives almost no isolation, so the rating has to allow for the dynamic component as well as the dead weight. Tell us the equipment weight, speed and the number of supports and we will confirm the correct model and hardness for your layout.
Quick Q&A
Q: Will it fit my existing bolt holes?
A: Usually yes, provided the thread and rating match - share the hole centres and we will confirm.
