A few Row Cylindrical Roller Slewing Bearings

A few-row cylindrical roller slewing bearings are mainly composed of an interior ring, outer ring, three-row rollers, cage (spacer block), sealing system, and so forth. This slewing bearing design and style is suitable for most huge-scale events with axial load and tilting minute, tremendous radial load, or decrease requirements for the frictional moment. A few-row cylindrical roller slewing bearings can at the same time bear axial, tilting, and radial loads. In comparison with the cylindrical cross roller slewing bearing, the load of each and every roller is decreased. Compared with double row roller slewing bearings, position contact becomes line speak to, and the get in touch with pressure is diminished.

Characteristics of three-row cylindrical roller slewing bearings

• Suited for highest axial loads and tilting times.
• Suitable for large connecting constructions.
• Usually, a few-row cylindrical roller slewing bearings are utilized for some heavy equipment.

The standard constructions of a few-row cylindrical roller slewing bearings are as underneath:

(1) Without having equipment

(2) Exterior gear

(3) Interior equipment

Software of three-row cylindrical roller slewing bearing

3-row cylindrical roller slewing bearing has 3 rings, which different the higher, reduced, and radial races by means of loads of every single row of rollers. It can have diverse loads simultaneously, and its load potential is the premier between the slewing bearings. It is strong and especially suitable for hefty-responsibility equipment which demand a huge working radius, such as bucket-wheel excavators, wheeled cranes, marine cranes, ladle turrets, weighty-obligation mobile cranes, and so forth.
