NTN is a world-renowned brand that specializes in the production and manufacturing of high-quality bearings, among other products. As a leading manufacturer located in China, we are proud to offer our range of NTN roller bearings to merchants and businesses outside of China.

Our products are widely used in various industries, including the automotive, aerospace, and industrial sectors. Our NTN roller bearings make use of advanced technology and materials which result in a product that meets the highest quality standards.

Some of the features and benefits of our NTN roller bearings include:

· High load capacity: Our roller bearings can withstand heavy loads, ensuring that they can handle the toughest applications.

· Long lifespan: Our bearings have a long service life, making them a cost-effective investment that will save you time and money in the long run.

· Low maintenance: Our roller bearings require minimal maintenance, resulting in less downtime and reduced repair costs.

· Precision manufacturing: Our bearings are manufactured to exacting standards, ensuring consistent quality and precise dimensions.

· Exceptional corrosion resistance: Our bearings are designed to withstand extreme environments and resist corrosion, ensuring that they function reliably in even the most challenging conditions.

Here is an overview of some of our most popular NTN roller bearing products:

Spherical Roller Bearings

Spherical roller bearings are used in heavy-duty applications where rotational speeds are slow and the load is high. These bearings have a spherical outside diameter and are used in applications such as paper mills, roll necks for rolling mills, and heavy machinery.

Cylindrical Roller Bearings

Our cylindrical roller bearings offer high radial load capacity, making them ideal for applications such as machine tool spindles and steel mills. These bearings are also available in various configurations, such as single-row, double-row, and four-row designs.

Tapered Roller Bearings

Our tapered roller bearings have a tapered raceway that allows the bearing to handle both radial and axial loads. These bearings are commonly used in automotive and industrial applications, including gearboxes, axle systems, and wheel hubs.

Needle Roller Bearings

Our needle roller bearings are designed for applications where space is limited and a high radial load is required. These bearings are commonly found in automotive transmissions, power tools, and pumps.

With our commitment to quality and excellence, you can trust that our NTN roller bearings will exceed your expectations. So why wait? Contact us today to learn more about our products and place your order. We look forward to doing business with you!

● Introduction

NTN roller bearings are produced by NTN Corporation. Founded in 1918, NTN Corporation is headquartered in Osaka, Japan. It has 11 factories in Japan and more than 20 wholly-owned production factories abroad. It is a world-renowned comprehensive precision machinery manufacturer, providing various types of machinery products, mainly bearings , mainly engaged in the production and sales of bearings and constant velocity universal joint precision machinery. With advanced precision machining technology and unique proprietary technology, NTN's bearings are widely used in various fields. NTN has many manufacturing plants and many service units in China, and we have maintained good cooperation with NTN and can distribute NTN roller bearings.

NTN bearings are widely used in orbiting satellites, aviation, railways and automobiles, paper making equipment, office equipment, industrial equipment and food machinery, etc.

● Bearing Series

The types of the bearings include deep groove ball bearings, angular contact ball bearings, self-aligning ball bearings, thrust ball bearings, pillow block bearings, needle roller bearings, spherical roller bearings, tapered roller bearings, cylindrical roller bearings and track rollers.

● Production Details

◆ Press forging process

Press forging is the production method of bearing ring forgings adopted by various bearing enterprises. The presses used are generally ordinary mechanical presses and inclined hole reaming machines. Bearing rings are forged on the press. Except for some small forgings that are directly forged on the press, the press is generally connected with the reaming machine, and the assembly line is organized for a fire forging line. The blank before reaming is provided by the press. It reduces the requirements for press forging, expands the size range of the forgings that can be processed, makes full use of the advantages of the rolling process, improves the production efficiency, and improves the dimensional accuracy and intrinsic quality of the forgings.

◆ Selection of bearing ring blanks

What is selected as the blank in actual production should be reasonably selected according to the specific situation. When selecting, consider the production batch size, the structural shape and size of the ferrule, the utilization rate of the workpiece material and the amount of turning, the supply capacity of the bad hair, the specific turning processing capacity (processing method, processing accuracy, etc.) and the satisfaction of bearing users. Special requirements (such as life, corrosion resistance, etc.)

● Bearing Multiple Demagnetization

Multiple demagnetization refers to a demagnetization method that repeats the same batch of products as sub-magnetization. During demagnetization, the demagnetization of a residual magnetism is related to the strength of the demagnetization field at the residual magnetic site and the angle of the residual magnetic direction relative to the direction of the demagnetization field. The closer the angle is to 90 °, the weaker the intensity, the smaller the demagnetization effect, and the distribution of the demagnetization field on the bearing is uneven, and the direction of the residual magnetism is also random, so in When demagnetizing, there will always be some residual magnets in the part where the demagnetization field plays the least, forming adverse factors. From the probability distribution characteristics, it can be seen that this adverse factor declines in equal proportion to the number of demagnetizations, that is, if the adverse factors account for 25% at the first demagnetization, only 6% for the second demagnetization, and only 0.4% are left in the third demagnetization. This is why it is necessary to demagnetize many times, but be careful not to keep the bearing in the same state from beginning to end.
