Four Row Tapered Roller Bearing

• Inner Diameter: 150-1580mm
• Outer Diameter: 210-1960mm
• Weight: 16.5-7800kg

The four-row taper roller bearing is a most common radial roll bearing. A bearing with such structure has a high bearing capacity and can bear the combined load which is mainly consisted by the radial load. Its radial loading capacity is 2.5 -3.5 times that of a single-row bearing. It can bear both very high radial and axial loads. Compared to a four-row cylindrical roller bearing, it has a relatively low speed due to the restriction of its structure.

The four-row tapered roller bearing can bear axial loads in double directions, so it can be used as a bidirectional thrust bearing.

The four-row tapered roller bearings are mainly used in the working roll necks of hot or cold rolling mills, and roll neck of cogging mills. They usually clearance fit with roll necks to being mounted and dismouted conveniently.
