Four Row Taper Roller Bearing

Rolling mills use four-row taper roller bearing products to deliver high-performance and long-life performance. These bearings increase operational effectiveness while lowering maintenance costs. They also have a brand-new kind of steel that improves strength and durability in harsh environments. This substance was created specifically for high-load bearings.

These four row tapered roller bearing  are especially well suited for large combined loads and have a very high axial load capacity. The rollers’ contact angle determines the axial load capacity, and the greater the contact angle, the greater the axial load capacity. They also have a four row layout, which aids in evenly distributing the load among the rollers. Additionally, for highly contaminated operations, we provide sealed four-row taper roller bearings. Additionally, these bearings have a high level of corrosion resistance and a long lifespan.

These tapered roller bearings have high bearing capacities and are primarily used for radial and axial loads. They can also restrict a shaft’s or housing’s axial movement in a single direction. They can also be paired head-to-head, back-to-back, or in tandem.

There are single-row, double-row, and four-row versions of these bearings available. A single axial load can be supported by a single-row taper roller bearing. Axial component force is created when a single-row taper roller bearing is overloaded with axial load. By pointing in the opposite direction, the bearings must balance this force.

Multi-row bearings include four-row taper roller bearings. They can support radial and axial loads and come in a variety of designs. A high degree of stiffness is also possible with this design. They can be used with equipment that operates at high speeds and for a variety of other purposes.

There are numerous sizes and designs of four-row taper roller bearings. They are frequently used as work roll and backup roll bearings in rolling mills. This kind of bearing is capable of supporting significant axial and radial loads. Simple roll neck bearing arrangements are also possible.

taper roller bearings with four rows
An example of a rolling mill bearing with four rows of rollers is a four-row taper roller bearing. These bearings’ layout maximizes a roller’s carrying capacity in a small assembly area. They have a long service life and can withstand heavy loads.

Four-row taper roller bearings perform similarly to double-row bearings when compared to other types of taper roller bearings, but they can withstand higher radial loads and have a slower maximum speed. Heavy engine machines are the main applications for these bearings. They come in both single-row and double-row arrangements.

The thrust load capacity of a single-row bearing is equal to 60% of its radial capacity. Double-row bearings can support their full radial load capacity. Additionally, they can manage thrust loads in both directions thanks to their double-row construction. The rollers’ contact lines are designed to either converge or diverge from the axis of rotation.

The contact state between the inner ring and the guiding flange serves as the foundation for the design of a double-row tapered roller bearing. Additionally, the angular misalignment of the flange and the external load on the bearing both have an impact. These three elements affect how long it remains fatigued. As a result, it’s crucial to select the right kind of bearing for the job.

High capacity is offered by four-row taper roller bearings, which are primarily used in rolling mill applications. They are ideal for applications where high capacity is required because they also have thin cross sections. Four-row taper roller bearings offer more capacity at slower speeds than their double-row equivalents.

taper roller bearings with four rows
In heavy machinery, four-row taper roller bearings are frequently used. These bearings’ caged design offers high dimensional accuracy and performance. Additionally, they last a lot longer than standard bearings do. To satisfy different needs, they come in a variety of designs. Some of these bearings have multiple seals, which extends their lifespan and lowers the amount of lubricant they require.

In inch and metric sizes, taper roller bearings are offered in single- and double-row configurations. They can support heavy loads thanks to their converged apexes and tapered surfaces.

Compared to double-row taper roller bearings, single-row taper roller bearings are more compact. They share two outer rings.
