Rubber shock absorber also known as rubber damper, rubber vibration isolator and rubber mounts. Rubber shock absorber has been widely used in machinery, motor vehicle, locomotive, water transportation, airplane and other aircraft. Rubber shock absorber can be used in anyplace where need to absorb and isolate shock. Rubber has high elasticity and flexibility, thus, its an excellent material to absorb shock and insulate noise. Besides, rubber has hysteresis and internal friction, they usually signify it in loss factor, the larger of the loss factor, the more obvious of the damping and themogenesis. Rubber shock absorber has excellent damping effect.
The shape of rubber shock absorber can be designed depends on customer needs, rigidity is adjustable, its damping ratio is larger than spring, shearing resistant, tension resistant, compression resistant and easy to install. While it has inferiors such as short service life, high inherent frequency, much limitation of using environment, some using environment should be controlled within -50℃ to 130℃, and chemical corrosive environment should choose suitable rubber material for the shock absorber. At present, NR, CR and NBR are three most commonly used rubber material for shock absorber.
Product features of rubber shock absorber:
- Applicable frequency range is 5-15Hz.
- Rubber shock absorber can isolate shock both in axial, lateral direction and turning direction.
- The damping of rubber material is much higher than metal material, and rubber is easy to form, and can closely bond with metal, therefore, we can deign and produce various shapes of rubber shock absorber, and they are in light weight, small volume and easy to install and change.
Application range of rubber shock absorber:
- Vibration isolation and noise control for high frequency rotary mechanical equipment. For example: draught fan, water pump, generator set, air-condition main engine, etc.. When rotational frequency larger than 1000rpm, it’s better to use rubber shock absorber.
- Stamping equipment, the impacting frequency had better avoid the inherent frequency of rubber shock absorber. For example: punching machine, die-cutting machine, press machine, etc..
- Since rubber shock absorber has vibration reduction function at any directions, so it has been widely used in automobile, aerospace and navigation.
- Other mechanical equipments.
Rubber is not suitable to all environments. Firstly, rubber will become embrittlement under -50℃, it will lose elasticity, so rubber shock absorber can not be used in over cold environment. Secondly, if temperature is higher than 125℃, rubber might be kindled up. So over-high temperature environment is not suitable for rubber material.
According to function, rubber shock absorber can be divided into:
- Rubber shock absorber which used for supporting all kinds of devices;
- Rubber bumper which used for absorbing impact;
- Rubber spring which used as machinery parts;
- Rubber shock absorber which used for eliminating specific vibration frequency;
- Rubber coupling also belongs to one kind of rubber shock absorber.
According to shape, rubber shock absorber can be divided into:
- Compression type. Rubber shock absorber which mainly used in compression direction, it has advantages of large loading bearing capacity.
- Shear type. Rubber shock absorber which mainly used in shear direction, it has small loading bearing capacity.
- Compound type. Rubber shock absorber which mainly used in compression direction and shear direction, it has features of both compression type and shear type.
- Tubular type. It can be used to reduce vibration at vertical direction, axial direction and warping direction.
Rubber shock absorber application sites includes: vibration isolation and noise control for high frequency rotary mechanical equipment, stamping equipment, automobile, aerospace and navigation.

- Rubber has high elasticity and viso-elasticity.
- Comparing to steel material, rubber has large elastic deformation and small elasticity modulus.
- Rubber’s impact rigidity is larger than dynamic rigidity, and dynamic rigidity is larger than static rigidity, which helps to reduce blastic deformation and dynamic deformation.
- Rubber is incompressibility material(Poisson ratio is 0.5);
- Rubber shape and hardness can be adjusted, which satisfied different requirements on rigidity and strength.
