elastomeric bearings

Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.Integral sea

Elastomeric bearings are a type of bearing used in various structural and mechanical applications to provide support, flexibility, and shock absorption. Here's a detailed introduction to elastomeric bearings:

1. Functionality:

• Elastomeric bearings are designed to support loads while allowing for movement and flexibility in structures. They are particularly useful in applications where there is a need for vibration isolation, shock absorption, and flexibility against misalignment.

2. Materials:

• These bearings are made from elastomeric materials, which are synthetic rubber-like polymers. The most common materials used include natural rubber, neoprene, EPDM (ethylene propylene diene monomer), and silicone. These materials offer high elasticity, durability, and resistance to weathering and aging.

3. Construction:

• Elastomeric bearings can be simple slabs or more complex shapes, such as cylinders or cones, depending on the application. They often have a steel reinforcement layer to provide additional strength and resistance to compression.

4. Applications:

• Bridges: Elastomeric bearings are widely used in bridge construction to accommodate thermal expansion and contraction, as well as to provide seismic isolation.

• Buildings: They are used in building structures, especially in areas prone to earthquakes, to absorb vibrations and provide flexibility.

• Pavement Joints: In pavements and roads, elastomeric bearings can be used in expansion joints to allow for thermal and traffic-induced movements.

• Machine Isolation: They can be used to isolate machinery from the structure they are mounted on, reducing the transmission of vibrations and noise.

5. Advantages:

• Durability: Elastomeric bearings have excellent resistance to UV radiation, ozone, and aging, making them suitable for outdoor applications.

• Maintenance-Free: They require minimal maintenance and have a long service life.

• Vibration Damping: They provide excellent damping properties, which help in reducing structural vibrations.

• Load Distribution: They can distribute loads evenly, reducing stress concentrations.

6. Disadvantages:

• Temperature Sensitivity: Elastomeric materials can be sensitive to high temperatures, which may affect their performance.

• Compressive Creep: Over time, the material may experience compressive creep, leading to a gradual loss of height.

7. Maintenance:

• While elastomeric bearings are low-maintenance, regular inspections are necessary to check for signs of wear, tear, or environmental damage. They should be replaced if they show significant deformation or cracking.

8. Environmental Considerations:

• Elastomeric bearings are often preferred over steel bearings in environmentally sensitive applications due to their recyclability and lower environmental impact.

In summary, elastomeric bearings offer a flexible and durable solution for applications requiring load support, vibration isolation, and flexibility. Their use in construction, infrastructure, and machinery is widespread due to their ability to withstand environmental exposure and provide long-term performance with minimal maintenance.
