Four Row Cylindrical Roller Bearings - China

Four-Row Cylindrical Roller Bearings

Product Description

Our Four-Row Cylindrical Roller Bearings are designed to provide exceptional performance and reliability, even in the most demanding environments.

With four rows of rollers arranged in a single assembly, these bearings can handle radial loads of up to 10, 000 kN and axial loads of up to 2, 000 kN.

The cylindrical roller bearings available at Jinfeng Bearing Manufacturing Co., Ltd offer a range of sizes and load capacities to suit different industrial applications.

These bearings offer several advantages over other types of bearings, including high radial load capacity, good resistance to shock and impact, and high-speed capability.

With their low friction, ease of installation and maintenance, and versatility in size and configuration, cylindrical roller bearings are a popular choice for heavy-duty applications.

Structure

Four-row cylindrical roller bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses.

Because they are normally mounted with an interference fit on the roll neck, four-row cylindrical roller bearings are well suited for rolling mill applications where the rolling speed is high.

Cylindrical Roller Bearing Size Chart:

The following table shows the different types of cylindrical roller bearings available at Jinfeng Bearing Manufacturing Co., Ltd, along with their sizes and load capacities:

Bearing Type Size Range (mm) Radial Load Capacity (kN)

N Type 20-200 76-900

NU Type 20-200 76-900

NJ Type 20-200 76-900

NF Type 20-200 76-900

NUP Type 20-200 76-900

NN Type (Double Row) 20-150 76-700

NNU Type (Double Row) 20-150 76-700

As seen in the table, the size range for cylindrical roller bearings varies from 20mm to 200mm.

Additionally, the radial load capacity of each bearing type ranges from 76kN to 900kN.

These variations in size and load capacity allow customers to choose the most suitable cylindrical roller bearing for their specific application needs.

Features and benefits

1 - Exceptional high load carrying capacity

Because of their high number of rollers, four-row cylindrical roller bearings are suitable for very heavy radial loads.

2 - Low friction (Roller end / flange contact area)

The open flange design, together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction.

3 - Enhanced operational reliability

The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.

4 - Separable and interchangeable

Four-row cylindrical roller bearings are interchangeable.

This facilitates mounting and dismounting, as well as maintenance inspections.

5 - High speed capability

The cage designs are suitable for high speeds, rapid accelerations and peak loads.

6 - Low cross-sectional height

The low cross-sectional height of four-row cylindrical roller bearings allows for relatively large roll neck diameters compared to the roll diameter.
