Bell Type Mounts PSP

The PSP series shock absorbers are designed to offer excellent radial and axial flexibility, making them ideal for isolating both vertical and horizontal vibrating components in suspended machinery.

The PSP base consists of two flat metal parts. The top metal plate is circular and features an internally welded nut for securing the mount to the machine frame. The lower metal plate has an elliptical shape with two holes for fastening to the machine's supporting structure.

These shock absorbers are particularly suitable for applications with low to moderate dynamic amplitudes, as their mounting stiffness ratio ensures effective vibration isolation.

FAQ

1. What is the difference between PSP Bell Type Mounts and ordinary rubber pads? Why does the price seem higher?

Your observation is correct. PSP Bell Type Mounts are not simple rubber blocks; they are engineered structural damping elements. Their unique "bell" (or lantern) shape allows for multi-directional, uniform deformation under compression, providing greater compression travel and more stable support. They typically feature an internal reinforcement layer and are made with durable, special-grade rubber. Therefore, they can handle higher loads and more frequent impacts. In short, they function more like an "active buffer system" rather than just passive pads, offering a higher level of protection for your heavy-duty precision equipment. Their long-term value far exceeds the initial price difference.
2. We have several large stamping presses in our workshop with significant vibration and noise. Can PSP mounts solve this? Is the effect noticeable?

This is precisely where the PSP series excels. For strong vibration and shock sources like large stamping presses and forging equipment, the high energy absorption and damping properties of PSP mounts are crucial:
1. Vibration Reduction: They significantly reduce the impact force transferred from the machine to the foundation. You will feel a substantial decrease in floor and surrounding structural vibration.
2. Noise Reduction: They interrupt the main path of structure-borne noise transmission. The "banging" impact noise of the machine becomes duller and quieter, leading to a notable drop in overall environmental noise.
3. Machine Stabilization: They reduce the machine's own shaking, improving operational smoothness. The effect is immediate. Many customers report a fundamental improvement in comfort levels in the surrounding area after installation.
3. Is the installation complicated? Do we need to damage our existing concrete floor?

Installation is very convenient, featuring a typical "drop-in-place" design. In most cases, no damage or special treatment of the existing floor is required. The standard procedure is to place the PSP mounts directly between the equipment base and the foundation during relocation or initial installation. Their wide base provides excellent stability. For equipment requiring precise leveling, some models come with height adjustment bolts. We provide detailed installation layout guides, and your engineering team can easily handle the installation.
4. If we need to move or reconfigure our equipment layout in the future, can these mounts be reused?

Absolutely. As long as the PSP mounts show no structural damage (such as severe tearing or permanent bulging), they will largely return to their original shape and performance after the equipment is removed. This makes them ideal for flexible equipment layout adjustments—a one-time investment with long-term benefits. Simply clean the surface before reinstallation.
