Four-row cylindrical roller bearings are available in many different designs.
With cylindrical or conical holes
Open or sealed
Four-row cylindrical roller bearings are used almost exclusively for roll necks of rolling stands, calenders and roll presses. Since these bearings are usually mounted on the roll neck with an interference fit, four-row cylindrical roller bearings are particularly suitable for rolling mill applications with high rolling speeds.
Because four-row cylindrical roller bearings can only carry radial loads, they are installed with deep groove or angular contact ball bearings, or with tapered roller bearings (radial or thrust design) that support axial loads.
Bearing characteristics:
Very high carrying capacity
Due to the large number of rollers, four-row cylindrical roller bearings are suitable for very heavy radial loads.
Low friction (roller end / flange contact area)
The open rib design (Figure 1), along with the roller end design and surface finish, facilitates the formation of the lubricant film, which results in lower friction.
long lasting
The logarithmic profile of the roller reduces the edge stress at the roller / raceway contact (Figure 2). The logarithmic profile also facilitates bearing misalignment and shaft deflection.
Improve operational reliability
The surface treatment of the contact surfaces of the roller and the raceway is beneficial to the formation of a hydrodynamic lubricant film.
Separable and interchangeable
The separate components of SKF four-row cylindrical roller bearings are interchangeable. This facilitates installation, removal and maintenance inspection.
High-speed capability
The cage design is suitable for high speed, fast acceleration and impact loads.
Low cross-section height
The low cross-section height of the four-row cylindrical roller bearing allows the use of a larger roller neck diameter compared to the roller diameter.
