Product Introduction

The performance of four row tapered roller bearings is basically the same as that of double row tapered roller bearings, but they have a greater ability to withstand radial loads and a lower limit speed. Four row tapered roller bearings can adapt to combined (radial and axial) loads at low and medium speeds, and are almost exclusively used in rolling mill applications, such as rolling mills. These bearings are designed for extremely high radial and axial loads as well as high-speed and impact loads, and are used in extreme adverse environmental conditions such as high temperature, water, and pollution. The new performance bearings can significantly reduce the overall life cycle cost of rolling mills.

Characteristics and advantages

● Long service life

The four cup design (four independent outer rings) provides optimal load distribution on all four rows of rollers.

● Improve operational reliability

Optimizing the surface treatment of the contact surface between the roller and the raceway is beneficial for the formation of a hydrodynamic lubricating oil film.

● Improved wear resistance

The bearings are made of extremely clean and uniform steel, which has undergone unique heat treatment to improve wear resistance.

● Complete interchangeability of bearings

Both with and without spacer bearings, as well as open and sealed bearings, are available in the same external size model

Product Application

Almost exclusively used in rolling mill applications, such as strip mills, profile mills, steel pipe mills, etc
