Description

As a manufacturer, we understand that when it comes to choosing the right bearings, there are a lot of options available in the market. However, our Matched Tapered Roller Bearings stand out for a number of reasons.

Firstly, each of our bearings is made from high-quality materials that ensure durability and reliability. We use premium-grade steel and state-of-the-art production techniques to craft bearings that can withstand the demands of various applications.

Secondly, our Matched Tapered Roller Bearings are designed to provide exceptional performance. Unlike other types of bearings, the tapered design allows for greater contact surface between the rollers and the outer raceway, resulting in increased load capacity and reduced friction. This means that our bearings are suitable for heavy-duty applications and can operate with greater efficiency, leading to increased productivity and lower costs.

Our Matched Tapered Roller Bearings are also highly customizable, and we can tailor them to meet the specific needs and requirements of a particular application. We offer a wide range of sizes, designs, and configurations to suit various applications, making our bearings versatile and adaptable.

Furthermore, we place great emphasis on quality control and rigorous testing to ensure that each bearing meets stringent international standards. All of our Matched Tapered Roller Bearings undergo thorough inspections and testing to ensure that they are free from defects and are suitable for use in a variety of applications.

Finally, we pride ourselves on our commitment to providing exceptional customer service. We have a team of highly trained and experienced professionals who are dedicated to meeting the needs and expectations of our clients. We work closely with our customers to understand their requirements and provide them with the best possible solutions.

In summary, our Matched Tapered Roller Bearings are a superior choice for those who are looking for high-quality, durable, and efficient bearings. With our focus on quality, customization, and customer service, we are confident that our products will meet and exceed your expectations. Contact us today to learn more about our Matched Tapered Roller Bearings and how they can benefit your business.

● Introduction

The outer ring or inner ring of matched tapered roller bearings is a whole, the small end faces of the two inner rings or outer rings are similar, and there is a spacer in the middle. The clearance is adjusted by the thickness of the spacer, and it can also be used to adjust the pre-interference of double-row tapered roller bearings. As with single row tapered roller bearings, bearing assemblies are separable and interchangeable for easy installation, removal and maintenance. The bearing can bear two-way axial load while bearing radial load, and it can limit the axial displacement of the shaft and the casing within the range of the bearing's axial clearance. It has a specific axial clearance or bearing preload. The bearing clearance has been given according to the user's requirements when the product leaves the factory, and the user does not need to adjust the bearing clearance. Matched tapered roller bearings have low friction, low noise, low vibration, long service life and high load carrying capacity for heavy radial and axial loads. Compared with the open structure bearing, the bearing life is increased by 20% to 40%, and the lubricant consumption is reduced by 80%.

Bearings are widely used in automobiles, trains, gearboxes, crushers, mining, metallurgy, industrial machinery, heavy machinery and other industries.

● Bearing Series

The types of the bearings include 313..-N11CA series, 320..-N11CA series, 322..-N11CA series and 329..-N11CA series.

● Production Details

◆ Processing of rollers

As the component that bears the load when the bearing is running, the roller is the weakest part in the roller bearing, and its quality greatly affects the working performance of the bearing (such as rotation accuracy, vibration, noise and flexibility, etc.), which is the main factor affecting the service life of the bearing factor.

There are many types of rollers, which can be divided into tapered rollers, cylindrical rollers, spherical rollers, spiral rollers and various needle rollers according to their shape and size. According to the accuracy, it is divided into 0, 1, 2 and 3 grades, which are respectively used in P2, P4, P5 and P6 and P0 bearings. The production of rollers at all levels has corresponding technical conditions. In addition, needle rollers are divided into three grades G2, G3 and G5.

◆ Process monitoring and measurement effectiveness

The role of the ISO 9001:2000 standard on "monitoring and measurement of processes" is that "when the planned results are not achieved, appropriate corrections and corrective actions shall be taken to ensure product conformity".

Monitoring and measurement of process output results, if it is shown that the expected specified goals are not achieved, it proves that the ability of the process to achieve the results is insufficient, and measures should be taken immediately, from the factors affecting the process: men, machinery, material, method and environment, namely 4MIE factors . Identify the main reasons, improve key processes, and ensure that the process achieves expected goals and product conformity by improving the process. Therefore, it is necessary to grasp each customer-oriented process, clarify input and output requirements, and set process goals. Provide appropriate resources, controls and procedures. Measure performance goals, evaluate whether the company has the ability to continuously and stably achieve process goals and produce qualified products, check the control of the process, and provide opportunities for improvement, which is conducive to the company's analysis and decision-making to ensure product compliance.

● Rolling Bearing Fault Diagnosis Technology

There are many fault diagnosis technologies for rolling bearings, mainly including vibration diagnosis technology, ferrography diagnosis technology, acoustic diagnosis technology, temperature diagnosis technology, oil film diagnosis technology and optical fiber monitoring technology. Among them, vibration diagnosis technology is the most widely used. It can realize online monitoring and fast diagnosis, it is especially suitable for fault monitoring of bearings in rotating machinery.
