Industrial Vibration and Noise Control with Cylindrical Rubber Mounts
Vibration is one of the quiet costs of production. Left uncontrolled, it shakes bolts loose, wears bearings, cracks pipework and turns rigid floors into loudspeakers. Cylindrical rubber mounts attack the problem at its source: placed between machine and base, they absorb dynamic energy before it reaches the structure. This article covers why they work, how to choose them, and what to expect on quality and delivery. The mounts come from JIUFU (Shanghai Songjiang Jiufu Shock Absorber Co., Ltd.) in Shanghai, China.
1. How Cylindrical Rubber Mounts Work
Each mount pairs an elastic natural-rubber body with white galvanised steel fittings, bonded in a single vulcanised moulding so it can be bolted firmly at both ends while still flexing under load. In service the rubber is deformed in compression and shear, converting vibration into a small amount of heat and damping the machine's movement.
Section Q&A
Q: Why rubber instead of a metal spring?
A: Rubber isolates and damps in one component, so it is compact and needs no separate damper or lubrication - ideal for machinery above 1200 rpm.
Q: Does it also protect the machine?
A: Yes - by absorbing dynamic energy it reduces fatigue on bearings, seals and fasteners, extending machine life.
2. Matching the Mount to the Machine
- VV: double male stud for machine-to-base clamping
- VD: male-female for one-sided mounting
- DD: compact female-female for small equipment
- DE / VE: threaded studs on a rubber body; VE covers M8/M10/M12
Section Q&A
Q: How do I pick between VV, VD and DD?
A: Follow the mounting points - two stud ends mean VV, a stud on one side means VD, two internal threads in a tight space mean DD.
Q: Can you supply non-standard threads?
A: Yes - other threads and dimensions can be produced to order.

Section Q&A
Q: How do I read the hardness value?
A: Harder carries more load with less movement; softer isolates better. Choose according to your point load.
4. Benefits for the Plant Floor
- Quieter operation and less structure-borne noise
- Less wear on bearings, seals and fasteners
- Reliable from -40C to +80C
- Resistance to ageing, heat, wear, moisture and oil
- Eco-friendly rubber, avoiding metal-spring recycling issues
- Fast, tool-free installation and easy replacement
Section Q&A
Q: How much quieter will the site be?
A: It removes the structural route that carries low-frequency rumble into the building. With the right sizing, the difference is clear.
5. Typical Equipment and Installation
Common duties include pumps, fans and air-handling units, generator sets, motors and inverters, compressors, centrifuges and vibration-sensitive instruments. Correct installation is about load and alignment:
- Size each mount by its point load - avoid too soft or too hard
- Confirm thread and height match the mounting points
- Account for temperature, oil and chemical exposure
- Keep the system's natural frequency clear of the machine speed
Section Q&A
Q: Can you recommend a model for me?
A: Yes - provide the equipment weight, speed and mounting dimensions and we will propose a model and hardness.
6. Quality Assurance and Supply
JIUFU products meet the ISO9001 quality system, with some models ROHS compliant. The plated finish passes a 96-hour salt-spray test, rubber-to-metal adhesion is about 40 kg/cm2, and fasteners are grade 8.8. The rubber is eco-friendly natural rubber with no reclaimed material, and we support reverse engineering with 3D drawing approval.
