A bearing is an essential element in machines that enables two parts to rotate smoothly with minimal friction. The bearing 6324 is a radial deep-groove ball bearing with the two-numbered 63 series and a 120mm outer diameter. The function of the 6324 bearing is to support the shaft and allow it to rotate freely. The 6324 bearing is designed to accommodate the axial load from both directions.
Deep groove ball bearings have a raceway constructed in a deep groove shape, which features a big complex of pool and ball. The geometry allows the balls to distribute the loads evenly, including radial and axial loads. Users usually find these bearings in applications with high speeds and moderate loads. The main parts of deep-groove ball bearings are the inner ring, outer ring, cage, and rolling elements (balls). The 6324 bearing will have two seals (named 6324-2Z) or two shields (named 6324-Z) on both sides to prevent the ingress of dirt and other contaminants; with shields, the grease is exposed to view. Sealed bearings will require minimal maintenance and last longer. The 6324 bearing can also come with a single or double groove on the inner ring, which helps to locate axial loads and gives a greater strength.
Industrial bearings are commonly found in the following areas:
The 6324 bearing can come in different materials that will offer varying benefits to the user in terms of load capacity, speed, operating temperature, corrosion resistance, and noise level. The more common ones are as follows:
The bearing's performance depends on 6324 bearing specification and maintenance practices.
Size
Ensure the inner and outer races fit snuggly in the designated shaft and housing. The rolling elements, commonly spherical or cylindrical, are, spacers, cages, and tracks. Choose them to withstand the expected load and movement. For example, a 6324 deep groove ball bearing has an inner diameter of 120 mm, an outer diameter of 300 mm, a width of 62 mm, and a bearing weight of over 10.5 kg. Verify the size against the sizing tables. The bearing's inner diameter (ID), outer diameter (OD), and width (W) correspond to the measurements.
Temprature
A 6324 bearing can operate well in low to high-temperature conditions. However, prolonged exposure to extreme temperature conditions can lead to premature failure. Añ bearing withstands temperatures between -30 °C to +110 °C. Use a thermometer to determine the temperature of the surrounding environment before choosing the bearing.
Lubrication
Deep groove ball bearings need lubrication to reduce friction between the inner and outer races. Lubricate the grooves after assembly and during routine maintenance checks. Many manufacturers pre-lubricate the bearing with grease or oil. Select the type based on the sealing mechanism and operating temperature. For the 6324 bearing, lithium complex greases work well. They are ideal for high-temperature applications and have good water resistance. Other compound soaps, like calcium, are more effective when the surrounding environment has water.
Load requirements
A 6324 bearing can support a radial load of 36,000 kg and an axial load of 3,000 kg. However, repeating the same movement or exposure to the same conditions can lead to fatigue. Consider the load and number of movements the bearing will make. Choose a bearing with a higher load capacity if it will bear a heavy strain.
Sealing
The environment influences whether to seal or shield the bearing. HAZ corrosion, extreme temperatures, dust, and water can cause the bearing to degrade over time. A V ring on the shaft or a lip seal on the outer race will help protect the bearing from harmful agents. Examine any harmful agent that comes in contact with the bearing.
The versatile performance and durability of the 6324 bearings mean they can be used in various industries and applications.
Heavy machinery
The bearing is commonly used in heavy machinery in the construction and mining industries, such as excavators, loaders, crushers, etc. Its ability to smoothly support machine shafts under heavy loads and its high-load capacity make it highly applicable.
Automotive industry
In the automotive industry, 6324 bearings are widely used in hubs and transmissions. Its great support power and ability to lower operating friction raise the shaft rotation's smoothness.
Logistics systems
The logistics system relies heavily on machine parts like conveyors and rollers. A 6324 bearing lowers machinery's friction and makes operation smooth, supporting it solidly.
Agricultural machinery
In agricultural operations, tractors and harvester machines move extensively. The tractor's and machine's axis movement relies on the bearings to lower friction and support smooth movement, solving the problem.
Wind power generation
In the wind power generation field, the bearing is the supporting component of the power generator axis and rotation disc, which supports the internal clockwork and translates the function of energy conversion.
Marine equipment
In the marine equipment field, the 6324 bearing supports the rotating shaft of machinery like cranes and winches, lowering friction to facilitate a smooth rotation and heavy load, thus ensuring the operating stability and reliability of maritime mechanical equipment.
Home appliance
The bearings 6324 also play an essential role in supporting stable and friction-reduced shaft rotation motion in appliances like washing machines and refrigerators.
Industrial buyers shopping for deep groove ball bearings, such as the 6324 bearing, should consider a few key factors.
Nature of Application
Users need to analyze their application and the role the bearing will play. Consider the load the bearing will support, its geometry, and if it will be exposed to contaminants or moisture. If the bearing will work in an application with harsh conditions, look for a high-performance bearing with robust sealing and resilient materials.
Performance Requirements
Consider the required performance of the deep groove ball bearing. Assess the need for load capacity, speed, and efficiency. Higher-performance applications require bearings with large load capacities and high rotational speeds. Choices that fulfill these performance requirements will enhance the efficiency of the equipment.
Lubrication needs
Some deep-ball-groove bearings need regular maintenance and relubrication. This need may pose logistical challenges in some applications. To avoid this issue, opt for bearings with permanent lubrication and extended lifespans.
Compatibility with existing systems
Ensure the bearing selected is compatible with the system it will be used to avoid costly adjustments and redesigns.
Cost-Effectiveness
When selecting deep-groove ball bearings for industrial applications, it is important to strike a balance between quality and cost. Cheap bearings will require frequent replacement, increasing long-term operational costs. Investing in high-quality bearings with excellent performance will save costs in the long run.
Q1: What do the numbers in bearing sizes mean?
A1: The bearing number includes the bearing type, size, design, and variant. For example, the 6324 deep groove ball bearing number indicates that it is a deep groove ball bearing, and 6324 is the size.
Q2: What does the internal bearing number mean?
A2: The internal bearing number indicates the specific way the bearing is made. It describes the internal structure and design, not the same as the external bearing number.
Q3: What do the letters after the bearing number mean?
A3: The letters after the bearing number usually indicate additional features or variations of the bearing, such as seals or tolerances.
Q4: How long will a 6324 bearing last?
A4: A 6324 bearing's lifespan depends on several factors, like the operating environment, load, speed, lubrication, and maintenance. In ideal conditions, the 6324 bearing can last 5-10 years or even longer.
