Complete specifications from 8mm to 150mm outer diameter size to meet various industrial needs.
Choose the right DD rubber shock absorber to meet specific industrial needs:
- Load bearing capacity: Select appropriate shock absorbers according to equipment weight, ensuring they can withstand both static and dynamic loads
- Material selection: Choose suitable rubber material based on industrial environment requirements (oil resistance, temperature resistance, chemical corrosion resistance)
- Size and shape: Ensure shock absorber dimensions match installation location for effective vibration isolation
- Hardness: Softer rubber typically provides better shock absorption but may have reduced durability
- Working environment: Consider temperature, humidity, and chemical exposure factors that affect performance and lifespan
- Installation and maintenance: Select shock absorbers that are easy to install and maintain to minimize downtime and costs
- Performance parameters: Match static compression, natural frequency, and dynamic stiffness with equipment operating frequency for optimal performance

This DD mount is moulded by Shanghai Songjiang Jiufu Shock Absorber Co., Ltd. in Songjiang District, Shanghai. The company opened its doors in 2003 and has stayed with a narrow specialism ever since: bonding natural and synthetic rubber to steel and aluminium for vibration control. Somewhere between fifty and a hundred people work across compounding, moulding, finishing and inspection.
Because mixing, bonding and curing happen in the same plant, the double deflection geometry of a 30*20 M6 mount can be tuned to a lighter or heavier machine load without the lead time of a new outside toolmaker. A quarter to a half of everything built here ships abroad, mostly to buyers who need drawings honoured batch after batch.
Compounds are mixed on site in natural rubber, EPDM and NBR, with a firm rule that no reclaimed rubber goes into the batch - a detail that matters for a mount expected to hold its 60 Shore A hardness after years of service. Materials are RoHS compliant. Rubber-to-metal adhesive strength is measured at 40 kg/cm2, and every mount is inspected before it is packed rather than sampled at random.

The site holds ISO 9001 certification for its quality system. Material declarations for RoHS and REACH are issued with shipments on request, and a third-party laboratory report can be commissioned where a project calls for one. Routine internal testing covers indentation hardness, static deflection under load, oil swelling and heat ageing, so a compound drift is spotted before a repeat order is packed.
Send the machine mass, fixing holes and available height - the engineers here will size compound and hardness to match.
The factory's certifications are not a marketing line: the scans below are the ISO management system certificates and the RoHS conformity document issued for the rubber expansion joint range, all currently in force.
b. For custom products, sample fee is determined by the detailed sample requirements. Normally, it takes 7-15 days.
1. You can provide 3D drawing to us, then our engineers and production teams evaluate the design and quote you the precise cost.
2. If you don't have 3D drawing, you can provide 2D drawing or draft with features details with full dimensions, we can draft 3D drawing for you with fair charge.
3. You can also customize Logo on the product surface, package, color box or carton.
4. We also provide assembly service for the OEM parts.
Additional Notes
Understanding the DD 30*20 M6 Double Deflection Rubber Mount Natural Rubber Oil and Weather Resistant Anti Vibration Mount: the mount pairs a resilient rubber body with plated steel fittings, absorbing vibration while keeping the fixing rigid. Correct sizing is the difference between effective isolation and premature wear.
- The natural-rubber element is ROHS compliant and free of reclaimed material.
- A temperature window of -40 C to +80 C covers cold stores and warm plant rooms.
- 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. Send your application details and our engineers will recommend a rating that keeps vibration and noise within your target.
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.
