Vibration isolation is a critical engineering consideration due to the detrimental effects that vibrations can impose on mechanical systems and structures. These effects include accelerated fatigue, increased wear, excessive noise, impaired operational precision, human discomfort, and potential structural damage.
By installing a vibration isolator between a vibration source and its mounting base or supporting structure, the transmission of vibrational energy is significantly reduced. In industrial environments, proper vibration isolation enhances equipment service life, improves operational efficiency, lowers noise levels, and safeguards both machine foundations and adjacent equipment from harmful dynamic forces. We mainly produce Rubber Mounts / Anti-Vibration mounts.
Common Shapes
-
Cylindrical Mounts: Provide uniform load distribution and are suitable for vertical and horizontal vibration isolation.
-
Conical Mounts: Offer greater flexibility and superior shock absorption for dynamic applications such as engines or compressors.
Rubber anti-vibration mounts generally consist of two main components: metal attachment elements and an elastomeric body.
- Metal Components:
These include washers, plates, threaded studs (male), threaded bushes (female), or various combinations such as male/male or male/female configurations, which facilitate secure attachment to machinery and supporting structures.
- Rubber Element:
The elastic core is commonly made from natural rubber (NR) or synthetic compounds—including SBR, NBR, CR, EPDM, or silicone—selected based on operational requirements such as temperature range, chemical resistance, oil compatibility, and environmental conditions.
- Hardness and Sizing:
Rubber hardness is customized according to application needs, typically specified in Shore A scales such as 45±5, 55±5, or 65±5 for cylindrical mounts.
Sizes vary widely; for example, cylindrical bobbin-type mounts may range from 6 mm to 200 mm in diameter, with heights from 4 mm to 100 mm, and accommodate threads from M3 to M24.
- Specialized Variants:
For harsh or corrosive environments, mounts may be constructed using stainless steel (AISI 304 or 316) and specialized rubber formulations that offer enhanced resistance to oils, high temperatures, or chemicals.
- Load Capacity and Design:
These mounts are engineered to support loads in compression, shear, or a combination of both, allowing for versatile performance across different vibration isolation scenarios.
Cylindrical or conical rubber-metal anti-vibration mounts are simple yet highly effective components for isolating machinery vibrations and shocks. Their key value lies in their ability to reduce vibration transmission, thereby protecting equipment, structures, and products. When selected properly for load, direction, rubber hardness, environment, and machine dynamics, they deliver good durability and cost-effectiveness.
