Types of Rubber Mounting

Rubber mountings come in a variety of types, each designed for specific applications. Some of the most common types of rubber mountings include the following:

• Cylindrical Mounts:

These are simple and common rubber mounts that are cylindrical in shape, with a bolt running through their center. They are highly effective in isolating noise and vibration in one direction. The rubber used in these mounts is often high-density and high-durometer, which makes them suitable for heavy-duty applications.

• Bobbin Mounts:

Bobbin mounts, also known as conical mounts, are made up of a cylindrical rubber component with a metal component attached to the top and bottom. The metal components are usually threaded, making them ideal for applications that require adjustability. Bobbin mounts can effectively isolate vibration and shock in multiple directions.

• Buffer Mounts:

Buffer mounts are often used to limit the movement of two parts relative to each other. They are commonly found in vehicle suspension systems and industrial machinery. Buffer mounts are available in different shapes, including circular, square, or rectangular, to cater to various design requirements.

• Machine Feet:

As the name suggests, machine feet are used to raise machinery and isolate it from the ground's vibrations. They are commonly used in heavy machinery and equipment. Machine feet are mostly available in bolt-down or stud configurations to accommodate different mounting methods.

• Engine Mounts:

These mounts are specifically designed to support and stabilize engines in vehicles and machinery. They are crucial for reducing noise and vibration transmission while allowing controlled movement of the engine. Rubber engine mounts come in different designs depending on the specific application. For instance, vehicles with front-wheel drive and rear-wheel drive have different engine mount configurations.

• Marine Mounts:

Marine mounts are designed to withstand harsh marine environments. They are commonly used in marine engines to isolate vibration and noise. The mounts are also resistant to corrosion, which is a common challenge in marine applications.

• Machine Isolators:

These are heavy-duty rubber isolator mounts that are designed to isolate machinery and equipment from vibration, shock, and noise. They are commonly used in heavy machinery and industrial equipment. Machine isolators come in various configurations to suit different load capacities and application requirements.

Specification and maintenance of rubber mounting

Machine mounts have various specifications, and users should choose the most suitable one for their application. Here are some general specifications of rubber mounts.

• Material

As mentioned earlier, machine mounts are made of rubber. However, not all types of rubber can be used to make mounts. The most suitable type of rubber is synthetic rubber. Synthetic rubber has good weather resistance, corrosion resistance, high elasticity, and high damping capacity. The rubber can be used to make mounts because it can be stretched and compressed without breaking.

• Load capacity

Load capacity is a key factor that should be considered while choosing a rubber mount. The load capacity of the mount should be slightly higher than the weight of the equipment it supports. This will ensure the mount effectively supports the machine without deforming or breaking.

• Size

The size of a rubber mount depends on how the mount will be used. The mount's size should be compatible with the machine or equipment's mounting point. For example, a large rubber mount cannot fit in a small space.

• Hole size

Hole size is a specification that is often overlooked. The function of a rubber mount is to reduce vibration. If the mount does not fit well on the machine's mounting point, it cannot effectively reduce vibration. Therefore, the hole size of a rubber mounting should be the same as the machine's mounting point.

Machine mounts have many functions, such as damping, noise reduction, and vibration isolation mounts. Over time, the mounts will wear out due to friction, overloading, corrosion, and other factors. Therefore, periodic maintenance of the mounts is essential. Here are some procedures for maintaining rubber mounts.

• Visual inspection

Visual inspection should be done regularly. During visual inspection, users should check the condition of the rubber mount. They should look for signs of wear and tear, such as cracks, deformation, and corrosion.

• Load capacity

As mentioned earlier, the load capacity of a mount should be slightly higher than the weight of the equipment it supports. Therefore, it is important for users to avoid overloading the mount.

• Replace the mount

After a long period of use, the rubber mount will wear out and its performance will be reduced. Therefore, users should replace the anti vibration mounts after a period of time. This will ensure the effective function of the mount and the safety of the equipment.

• Clean the mount

Users should clean the rubber mount periodically. They can use a clean, damp cloth to wipe the mount to remove any dust or debris.

• Check the alignment

During maintenance, users should check the alignment of the rubber mount. Misalignment of the rubber mount may affect the stability of the equipment. If the alignment of the rubber mount is incorrect, users should adjust it in time.

How to Choose Rubber Mounting

• Consider the Load Needs

Consider the load needs of the machinery or equipment when choosing a rubber mount. The mount must support the weight of the equipment or machinery while allowing some movement and vibration control. The rubber mount must also be able to handle the weight of the equipment or machinery without deforming or failing prematurely.

• Check the Mounting Position

Check the mounting position of the equipment or machinery. For example, if the rubber mount is being used to support an engine, consider the available mounting points and the space around the mounting points. Choose a rubber mount that fits the available space and mounting configuration. The rubber mount should be installed securely and in a way that allows it to perform its intended function.

• Assess Environmental Factors

Assess environmental factors such as temperature, moisture, and exposure to chemicals or oils. Choose a rubber mount made from materials that can withstand the environmental conditions of the application. For example, if the rubber mount will be used outdoors or in a damp environment, choose a mount that is resistant to moisture and UV exposure.

• Consider the Type of Vibration

Consider the type of vibration or movement that needs to be controlled. Different types of rubber mounts are designed to control different types of vibration, such as low-frequency or high-frequency vibration. Choose a rubber mount that is designed to control the specific type of vibration present in the application. This will ensure effective vibration control and prevent premature wear or damage to the equipment or machinery.

• Consult a Supplier

Consult a supplier who specializes in rubber mounts. The supplier can recommend the best type of mount for the application based on factors such as load requirements, vibration control needs, and environmental conditions. The supplier can also provide guidance on installation and maintenance of the rubber mount to ensure optimal performance and longevity.

• Test and Evaluate

After selecting a rubber mount, conduct testing and evaluation to ensure it meets the performance requirements of the application. Monitor the mount over time to assess its durability and effectiveness in controlling vibration. If necessary, make adjustments or consider alternative mounts to achieve the desired results.

• Consider Future Maintenance

When choosing a rubber mount, consider future maintenance requirements. Choose a mount that is easy to install and remove, which will simplify maintenance tasks. Additionally, consider the expected service life of the mount and plan for periodic inspections and replacements, if necessary, to ensure continued performance.

How to DIY and replace rubber mounting

Replacing rubber mounts is a straightforward process, and it is one of the most common maintenance procedures. Before changing the mounts, ensure the replacement parts are readily available. Prepare the required tools for the job. A socket wrench set, torque wrench, and ratchet are some of the tools needed for a successful replacement. The process requires the mounting to be measured to ensure the new mounting is the right fit.

Loosen the fasteners and remove the old rubber mount from the equipment or machinery. Clean any debris and dirt that may have built up. This also gives a clear view of the mounting points. The next step is to position the new rubber mount in place and secure it with the fasteners. It is important to use the correct torque settings to avoid over-tightening, as this may damage the rubber mounts.

After securing the mounts, check to ensure they are properly aligned and the machinery is functioning as expected. If any issues arise, it is important to investigate further and address them immediately.
