Triple Row Roller Slewing Bearings


Type: External gear, Internal gear, No gear
Feature: 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. The solid structure and the large axial and radial dimensions.
Application: 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.
Material: 50Mn/42CrMo/S48C/42CrMo4/16Mn

Triple row roller slewing bearings are specifically designed for extremely heavy-duty applications requiring exceptional load capacity and maximum structural stability. Featuring three separate rows of rollers—dedicated to carrying axial loads, radial loads, and overturning moments respectively—this bearing design ensures optimal load distribution and superior performance under complex working conditions.

The separated load paths significantly reduce internal stress and enhance rigidity, allowing the bearing to withstand very high axial forces, radial loads, and tilting moments simultaneously. Compared with ball-type and cross roller slewing bearings, triple row roller slewing bearings offer the highest load-carrying capacity and outstanding resistance to shock, vibration, and deformation.

Manufactured from high-quality bearing steel with precision-machined raceways, these bearings deliver smooth rotation, low wear, and long service life even in harsh environments. Triple row roller slewing bearings are widely used in large cranes, ship deck machinery, bucket wheel excavators, stackers and reclaimers, offshore equipment, and heavy material-handling systems.

Available with internal or external gears and customizable dimensions, triple row roller slewing bearings provide reliable, long-term performance for large rotating structures operating under extreme loads.
