Bell Type Mounts PDR

PDR 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 12 kilograms to 1200 kilograms.

FAQ

1. I keep hearing about different "bell type" mounts like VBL or PSP. What makes the PDR series specifically different? When should I consider PDR?

That's an excellent question for comparing options. Think of the PDR series as the versatile workhorse within our bell-type family. While all share the efficient "bell" shape, PDR is engineered for reliable, cost-effective performance in standard industrial applications. It's the go-to choice when you need the proven benefits of bell-type isolation—like progressive load deflection and stable damping—for common machinery without requiring the specialized properties of other series. Consider PDR for your general-purpose machine foundation isolation, HVAC unit mounting, or standard production equipment where consistent vibration control is the primary goal.
2. Our factory layout changes occasionally. If we need to move a machine, can we easily reuse the PDR mounts, or are they a one-time installation?

Reusability is a key design advantage of the PDR series. They are built as durable, resilient components meant for long-term service. When a machine is relocated, the PDR mounts can typically be cleaned, inspected, and reinstalled under the new base, provided they show no physical damage like deep cuts or tears. This makes them a sustainable and cost-saving solution for dynamic manufacturing environments, protecting your investment beyond a single machine lifecycle.
3. Can the PDR mount be used in combination with other vibration control methods, like inertia blocks or floating floors?

Absolutely. In fact, PDR mounts are often a preferred component in integrated vibration isolation systems. They work exceptionally well when installed between an inertial mass base (concrete block) and the building floor, or as the primary isolator under equipment on a raised access floor. Their predictable stiffness and damping characteristics make them ideal for hybrid vibration control solutions in sensitive environments like labs or recording studios.
