Three Row Cylindrical Roller Slewing Bearing

The Triple-row Roller Slewing Bearing has three seating rings, which separate the upper, lower and radial raceways. It can specify the loads of each row of rollers. Moreover, its load carrying capacity and it can bear different loads simultaneously. Due to the solid structure and the large axial and radial dimensions, it is applicable to the heavy equipment with large diameter such as bucket-wheel excavator, wheeled crane, ship crane, harbor crane, ladle turrets and heavy-duty mobile crane, etc.

Range of external diameter: 300mm to 6000mm

Ring material: 42CrMo / 50Mn/ C45

Ball/roller material: GCr15

Cage material: steel 20 or ZL102 cast aluminum alloy

Spacer material: nylon 6 / nylon 66

Quenching hardness of raceway: HRC55-62

Overview of Three Row Cylindrical Roller Slewing Bearing 

The LTZC three row cylindrical roller combined slewing bearing mainly consists of the components such as inner ring, outer ring, three rows of rollers, cage (spacing blocks), a seal device etc. This slewing bearing design is suitable for most applications where a large axial load and tilting moment, or with a larger radial load, or with a low requirement for friction moment.

Features of Internal Gear Slewing Bearing

The Triple-row Roller Slewing Bearing has three seating rings, which separate the upper, lower and radial raceways. It can specify the loads of each row of rollers. Moreover, its load carrying capacity and it can bear different loads simultaneously. Due to the solid structure and the large axial and radial dimensions, it is applicable to the heavy equipment with large diameter such as bucket-wheel excavator, wheeled crane, ship crane, harbor crane, ladle turrets and heavy-duty mobile crane, etc.
Note:
1.n1 is the number of holes of lubricant, equally spaced, with oil cup M10×1 JB/T7940.1-JB/ T7940.2
2.The fastening holes n-dn1 and n-dn2 can be replaced by the tapped hole; the tooth width b can be changed to H-h
3.The tangential force of the internal gear is the maximum tangential force; the rating tangential force is the half of the maximum tangential force

4.The addendum modification coefficient of internal teeth is 0.2
