Bell Type Mounts PDRS

PDRS series shock absorbers, with a simple structural design and the cooperation of metal parts, are easy to install. Natural rubber provides a relatively large static disturbance. It has a good shock absorption effect at a vibration frequency of 15 Hz (900 revolutions) - it can reduce 90% of the vibration. The load range is wide, from 60 kilograms to 400 kilograms.

FAQ

1. The product code has an "S" in it. Does PDRS mean it's a "special," "safety," or "heavy-duty" version of your standard PDR mounts?

You're right to notice the suffix. In our PDR series, the "S" often designates variants with specific enhanced performance characteristics or construction features. While the core bell-type design provides excellent isolation, the PDRS models may incorporate elements like higher-grade damping compounds, integrated steel safety housings, or specialized platings for particular challenges. It's best to tell us about your specific application's needs—whether it's for heavy cyclic loading, enhanced stability in safety-critical installations, or operation in chemically aggressive environments—and we can confirm if a PDRS variant is the optimal match for your demanding industrial vibration control project.
2. Our primary concern is safety and stability. If a machine's mount fails, it could be catastrophic. How does the PDRS design address failure risks compared to a basic rubber pad?

Safety is paramount, and the PDRS design philosophy incorporates inherent fail-safe characteristics and robust construction. Unlike a simple pad that can split or squish out, the bell-type geometry and reinforced structure are engineered to contain the rubber element and maintain integrity even under extreme overloads. Many PDRS variants are designed for predictable, controlled deflection, meaning the machine will settle safely in a known manner if massively overloaded, rather than collapsing suddenly. This makes them a preferred choice for safety-conscious plant engineering and risk mitigation in machinery installation.
3. We sometimes have issues with mounts "walking" or creeping out of position over time due to machine vibrations. Does the PDRS design help prevent this?

Yes, this is a common issue that the PDRS series is well-suited to address. The combination of its inherently stable geometric shape and high-friction elastomer surfaces provides significant resistance to lateral movement or "walking." For applications with pronounced lateral forces, many PDRS models can be specified with integrated bolt-down holes or mounting flanges, allowing for positive mechanical attachment to both the machine and the foundation, ensuring permanent, maintenance-free positioning for your equipment.
