WDJM four-row tapered roller bearing is a specially designed rolling bearing with a structure composed of four rows of tapered rollers. This bearing design is designed to carry both radial and axial loads and is capable of handling appropriate deflection loads. The following is a general introduction to four-row tapered roller bearings:

Structural features: Four-row tapered roller bearings consist of inner rings, outer rings, rollers and cages. Compared with two-row tapered roller bearings, four-row tapered roller bearings have more rolling elements and therefore can withstand higher radial and axial loads.

Carrying capacity: Four-row tapered roller bearings are suitable for applications that need to bear large radial and axial loads, such as rolling mills, metallurgical machinery, excavation equipment, etc. Due to its special structural design, it can provide high load-bearing capacity and good rigidity.

Application fields: Four-row tapered roller bearings are commonly used in rolling mill equipment in steel, aluminum and other metal processing industries, and are used for rolling steel plates, aluminum plates and other materials. In addition, it is also widely used in some heavy machinery equipment and construction machinery.

Aligning performance: Some four-row tapered roller bearings have an aligning function and can adapt to different working conditions and axial deviation, thereby improving the performance and service life of the bearing.

Lubrication and maintenance: In order to ensure the normal operation of four-row tapered roller bearings, regular lubrication and maintenance are necessary. Proper lubrication can reduce friction and wear and extend the service life of bearings.

In general, four-row tapered roller bearings play an important role in heavy machinery and equipment due to their high load-bearing capacity, good alignment performance and reliability. They are one of the key components that are indispensable in many industrial fields.

BT4B series: For example, BT4B 328817 E1/C475, BT4B 332822/HA1, etc.

BT4 series: For example, BT4-8022 G/HA1VA919, BT4B 332967/HA4, etc.

BT4-000 series: For example, BT4-0004 G/HA1, BT4-0009 G/HA1VA901, etc.

BT4B 330742 A/HA4: This is another common model, suitable for some heavy machinery equipment, such as rolling mills.

BT4-8014 G/HA1VA901: This is another common model, commonly found in equipment in metallurgy, mining and other industries.

These models are just some of them. There are actually more four-row tapered roller bearing models, and each model may have different sizes, load-bearing capacities, and applicable scenarios. Selection of the appropriate model should be determined based on specific application needs and equipment parameters. It is recommended to consult a professional mechanical engineer or bearing manufacturer for more accurate advice during selection and application.
