Industrial machinery generates continuous vibration during operation. If these vibrations are transmitted directly to supporting structures, they can lead to excessive noise, structural fatigue, premature equipment failure, and increased maintenance costs. PSP Bell Mounts are specially designed rubber vibration isolators that effectively absorb vibration and shock while maintaining excellent stability under both static and dynamic loads.
Featuring a compact bell-shaped rubber structure, PSP Bell Mounts provide outstanding vibration isolation, long service life, and easy installation. They are widely used in HVAC systems, industrial machinery, electrical equipment, and power generation applications where reliable vibration control is essential.
What Are PSP Bell Mounts?
PSP Bell Mounts are high-performance rubber vibration isolators consisting of a specially formulated elastomer bonded to precision-machined steel mounting plates. The bell-shaped design distributes stress evenly throughout the rubber body, improving durability and providing consistent vibration isolation over a wide range of operating conditions.
Compared with conventional cylindrical rubber mounts, PSP Bell Mounts offer:
- High load capacity
- Constant installation height
- Excellent dynamic stiffness characteristics
- Superior fatigue resistance
- Outstanding impact absorption
- Low creep deformation
- Long maintenance-free service life
Typical Natural Frequency:
- Axial: 7 Hz
- Radial: 3–5.5 Hz
These characteristics make them particularly suitable for high-frequency vibration isolation.

These mounts help protect sensitive electrical components from continuous mechanical vibration.
Generator Sets
Generator systems create both low-frequency engine vibration and high-frequency mechanical vibration.
PSP Bell Mounts are widely used on:
- Diesel generator sets
- Gas generators
- Marine generators
- Emergency backup generators
- Containerized power stations
- Portable generators
- Mobile power units
They reduce vibration transmission to concrete foundations and surrounding structures while lowering operational noise.
Key Benefits of PSP Bell Mounts
Industrial users choose PSP Bell Mounts because they deliver multiple performance advantages:
- Excellent vibration isolation performance
- High-frequency vibration absorption
- Stable installation height
- Wide load range
- Outstanding fatigue life
- Superior impact resistance
- Low permanent deformation
- Corrosion-resistant metal components
- Compact structure
- Easy installation
- Maintenance-free operation
- Long service life
- Reliable operation in continuous-duty environments
Why Does High-Frequency Vibration Require Special Rubber Mounts?
Many industrial machines operate at high rotational speeds, where vibration frequencies can easily exceed several hundred cycles per minute. Ordinary rubber mounts may become too stiff or lose effectiveness under these conditions.
PSP Bell Mounts are engineered with optimized rubber geometry and carefully selected elastomer compounds that maintain effective isolation at higher operating frequencies. Their low natural frequency allows the mount to isolate vibration instead of amplifying it, improving equipment stability while protecting nearby structures.
How Do PSP Bell Mounts Reduce Maintenance Costs?
Excessive vibration accelerates wear on bearings, seals, couplings, piping, electrical connections, and structural supports.
By isolating vibration at its source, PSP Bell Mounts help:
- Reduce bearing failures
- Prevent pipe fatigue cracks
- Minimize bolt loosening
- Lower equipment noise
- Extend motor life
- Protect electronic components
- Reduce downtime
- Improve operational reliability
For facilities operating around the clock, these benefits can significantly reduce total lifecycle costs.
Frequently Asked Questions
Q1: What equipment is most suitable for PSP Bell Mounts?
PSP Bell Mounts are ideal for equipment that generates continuous vibration, including fans, pumps, compressors, HVAC equipment, transformers, electrical cabinets, generator sets, cooling towers, and various industrial machinery. They are particularly effective where high-frequency vibration isolation is required and where stable equipment support is essential.
Q2: Can PSP Bell Mounts be used outdoors?
Yes. With properly selected rubber compounds and corrosion-protected metal parts, PSP Bell Mounts can operate in outdoor environments. For applications exposed to UV radiation, moisture, salt spray, chemicals, or extreme temperatures, different rubber materials such as EPDM, NBR, CR, or other specialized elastomers can be selected to match the operating conditions and maximize service life.
Q3: Are PSP Bell Mounts maintenance-free?
Generally, yes. Since there are no moving mechanical components, the mounts require very little maintenance. Periodic visual inspection is recommended to check for signs of rubber aging, overload, or environmental damage, especially in harsh industrial environments. Under normal operating conditions, they provide many years of reliable service.
Q4: How should the correct PSP Bell Mount be selected?
Selection should be based on several key factors, including equipment weight, number of mounting points, center of gravity, operating speed, vibration frequency, installation space, environmental conditions, and required vibration isolation performance. Choosing the proper load range ensures the mount operates within its designed deflection, providing optimal vibration isolation and long-term reliability.
Q5: What advantages do PSP Bell Mounts offer over conventional rubber mounts?
The bell-shaped design distributes stress more evenly throughout the rubber body, resulting in higher load capacity, lower creep, improved fatigue resistance, better impact absorption, and superior dynamic performance. Compared with conventional cylindrical rubber mounts, PSP Bell Mounts generally provide more stable vibration isolation, especially for equipment operating continuously under dynamic loading conditions.
