The NTN 6304 ZZ ball bearing is a popular choice among ***strong, sturdy, durable ball bearings***. It is used in the automotive to aerospace sectors, among many other industrial applications. The NTN 6304 ZZ ball bearing is categorized based on the type, hence the following list.
This is a common ball bearing and can carry radial and axial loads. It is commonly used because it is suitable for various ***rotating applications***.
This bearing looks similar to a single-row deep groove, save for the fact that it has two rows of balls. It allows excellent load-carrying capacity since it can support both radial and axial loads simultaneously. It is ideal for applications with heavy load demands.
The angular contact bearing is specifically designed to support axial loads in one direction. It can also carry radial loads. The characteristic feature that sets these bearings apart from others is that the raceways are oriented at an angle to each other.
The self-aligning bearing comprises an inner ring with two balls and an outer ring. This design allows for some misalignment, which helps accommodate shaft deflections or misalignment.
The 6304 ZZ ball-bearing shield inhibits the intrusion of contaminants such as dust and dirt, which could affect bearing performance. Sealed ball bearings have seals that prevent the entry of contaminants and help retain the lubrication within the bearing.
As previously stated, the NTN ball bearing comprises a steel ball and other components. Often, the materials used in the composition of bearings affect their performance, hence the following list.
The balls, which are made from high-carbon steel or stainless steel, offer excellent hardness and wear resistance. This material was used to provide smooth motion and minimize friction. Steel balls are commonly used because they offer a good balance between strength and durability.
The material for the inner ring is similar to that for the outer ring. High-grade steel is used because it provides the rigidity required to maintain the raceway's geometry. This ensures proper rolling of balls and minimizes wear.
Just like the inner ring, the outer ring is made from high-quality steel. The steel is crafted into a precisely machined groove wherein the balls will roll. The steel ensures it remains durable and able to withstand the stresses associated with ***rotating loads***.
The cage, also known as a retainer or separator, is an integral part of the 6304 ZZ ball bearings. It is commonly made from stamped steel, polymer, or brass. The cage's primary purpose is to hold the balls evenly spaced so that each ball receives equal load during operation.
One other component of the NTN 6304 ZZ ball-bearing shield is that it is pre-filled with grease. The grease comes from the manufacturer and provides optimal lubrication. It reduces friction between moving parts and prevents overheating.
NTN ball bearings are used in many places. Here are some of the more popular applications.
One common application of the NTN ball-bearing shield is in automotive components such as engines, transmissions, wheels, and alternators. In these parts, the bearings provide smooth rotation and support for various moving parts while also enduring heavy loads and ***vibrations***.
These bearings are also used in motors, gearboxes, conveyors, pumps, fans, and other industrial machines. Here, the ball bearings help reduce friction and wear, hence ensuring the machine operates efficiently.
In aerospace, the 6304 ZZ ball bearings are used in critical components like aircraft engines, landing gear, and control surfaces. They help ensure precision, reliability, and performance under extreme conditions. For these properties, the ball bearings are lightweight, durable, and able to withstand high speeds and temperatures.
The 6304 ZZ ball bearings can also be found in various ***built-in and ordinary household appliances***. They are used in the motors and rotors of washing machines, refrigerators, fans, and other appliances that require smooth rotational motion.
In robotics, the NTN shielded ball bearings support joints, wheels, and other moving parts. They enable smooth, precise movement, reducing friction and increasing the robots' longevity.
The 6304 ZZ ball bearings can be customized to suit buyers in bulk for various applications. Here are some common characteristics aspects that can be adjusted.
As far as branding goes for the NTN 6304 ZZ ball bearings, here are some commonly applied branding strategies.
Here are some important considerations business owners should keep in mind when selecting the NTN 6304 ZZ ball bearings for resale.
This bearing's load capacity help determines how much load it can handle without being overstressed. The longer or heavier the load is, the longer the bearing will be required to carry it. Therefore, business owners should ensure the bearing they select has a higher load capacity than the average their customers will require for a specific application.
Like the other ball bearings, the 6304 ZZ is rated for a certain limit rotational speed. Going above this limit can increase bearing wear and minimize its lifespan. Therefore, business owners should get bearings in which the operational speeds of their customers' intended applications are within the bearings' operational speed range.
A fit is a relationship between the rolling element and the rings. It can either be a loose or tight fit. In some cases, the best fit can be influenced by factors like shaft and housing material and the NTN 6304 ZZ ball-bearing operating conditions. Therefore, business owners should get bearings that provide the best fit for their customers' applications.
Customers will often operate their applications in diverse environmental conditions. Some common conditions to consider include corrosive environments, such as the chemical industry, where the bearings may be exposed to harsh chemicals, and high temperatures, where the bearings may be exposed to extreme heat. Business owners should ensure they select bearings able to withstand the environmental conditions of the applications for which they plan to sell the bearings.
The NTN 6304 ZZ ball bearing is protected by a shield, which helps retain its lubrication. However, for the first time, the bearings may need to be lubricated to prolong their lifespan. Therefore, business owners should ensure they select lubricants that will be compatible with the operating conditions of their customers' applications.
Manufacturers of these ball bearings engrave or print the outer race with various identifiers, such as the manufacturer's name, the bearing's part number, and the manufacturer's logo. Customers can start by checking these identifiers. They will also need to check other elements, such as the bearing's size, the information on the packaging, and some personal tests, such as the weight and sound. After this, they should compare all the information with that of the genuine bearing online and on manufacturer's websites. To improve the experience further, customers can use tools like the QR code scanner to automate the process.
The average lifespan of NTN's most popular ball bearings is 10–20 years. However, it is important to note that many factors can influence this, including the application, load, operating environment, and maintenance. So they can't always be expected to last so long.
Enterprises rarely maintain the bearings themselves. In most cases, the maintenance work is done by the OEM department or a certified service provider. These technicians have the knowledge necessary to maintain and service the bearings properly. Furthermore, the 6304 ZZ ball bearings frequently come with maintenance instructions from the manufacturers that detail how to care for and maintain the bearings sufficiently.
To keep its freshness, the 6304 ZZ ball bearings should be carefully kept in a dry and humid environment. They should also be kept from direct sunshine, heat, and contaminants such as dust, dirt, and chemicals. The bearings should also be kept in their original packaging so the shields can protect them. Most importantly, the bearings should be kept at a stable temperature so the lubricants will not be separated.
With multiple applications in the automotive, industrial, aerospace, and home appliance industries, the NTN 6304 ZZ ball bearings have proven themselves a popular choice among ***ball bearing uses***. Its durability, longevity, and low-maintenance requirements make it so. Its customization options and branding strategies also make it a favorite among many businesses. Businesses can confidently purchase it from reputable suppliers on Alibaba.com, knowing it will be in good condition upon arrival.
