FOUR ROW TAPER ROLLER

Four row tapered roller bearings can accommodate combined (radial & axial) loads at low to moderate speeds. They are used almost exclusively in work roll applications such as rolling mills.

BEARING FEATURES

Depending on their design, four-row tapered roller bearings provide the following main features and benefits:

Long service life

The four-cup design (four separate outer rings) provides optimal load distribution over all four rows of rollers.

Enhanced Operational Reliability

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

Improved Wear Resistance

In particular , SKF explorer bearings are made of extremely clean and homogenous steel and undergo a unique heat treatment, which improve the resistance to wear.

Description

Four-row tapered roller bearings are a type of rolling-element bearing designed to support both radial and axial loads in large machinery, such as rolling mills. Here are some key features and characteristics of four-row tapered roller bearings:

1. Design: Four-row tapered roller bearings consist of four rows of tapered rollers arranged in a single inner ring and two outer rings. The inner and outer rings have tapered raceways that converge at a common point on the bearing axis, allowing the bearing to accommodate both radial and axial loads.

2. Load Capacity: Four-row tapered roller bearings can support high radial and axial loads and are designed for use in heavy-duty applications, such as rolling mills and gearboxes.

3. Tapered Rollers: The tapered shape of the rollers enables the bearings to support axial loads in one direction, while still providing good radial support. The angle of the taper is designed to optimize the bearing’s ability to handle both types of loads.

4. Variants: Four-row tapered roller bearings are available in several variants, including different designs of the inner and outer rings, as well as different cage designs. These variants allow for customization to suit specific application requirements.

5. Precision and Tolerance: Four-row tapered roller bearings are manufactured to high precision and have tight tolerances to ensure smooth operation and long service life in demanding applications.

6. Lubrication: Proper lubrication is essential for four-row tapered roller bearings to ensure smooth operation and prevent premature wear. They can be lubricated with grease or oil, depending on the application requirements.

7. Applications: Four-row tapered roller bearings are used in various industries and applications, including rolling mills, gearboxes, and heavy machinery, where high load capacity and durability are required.

Overall, four-row tapered roller bearings are known for their high load capacity, durability, and ability to handle both radial and axial loads in heavy-duty applications. They are a popular choice in industries where reliable performance under heavy loads is critical.
