S20-125E1 Bore 2994.152 Mm, Single Row Vertical Thrust Ball Slewing Rings With External Gears
The S20-125E1 Slewing bearings are widely used in mechanical equipment that needs to bear heavy loads and achieve smooth rotation, such as engineering machinery (excavators, truck cranes), wind power generation (yaw and pitch bearings), port machinery (stack-reclaimers), robots (industrial robot rotary tables), medical equipment (CT scanner rotating frames), and new energy (solar tracking systems), among other fields.
The S20-125E1 bearing is a Single Row Vertical Thrust Ball Slewing Rings With External Gears with an inner diameter of 2994.152 mm , an outer diameter of 3405.0478 mm, a width of 138.176 mm. 50Mn or 42CrMo rings, chrome-alloy steel rolling mlement. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
S20-125E1 bearings ( 2994.152 mm x 3405.0478 mm x 138.176 mm) have the advantages of Integrated transmission, ultra-high load capacity, simplified structure, and are therefore widely used in the Sewage and water treatment, Clarifiers, thickeners and rotary distributors.

The S20-125E1 Slewing bearings mainly consist of an inner ring, an outer ring, rolling elements (steel balls or rollers), spacers, seals, and mounting holes. Gears can be integrated into the inner and outer rings for direct meshing with the drive mechanism to achieve power transmission.
Slewing bearings can simultaneously withstand axial loads, radial loads, and overturning moments, exhibiting high load-bearing capacity and outstanding rigidity. Their integrated structure facilitates installation, minimizes space occupation, ensures smooth operation, and reduces maintenance intervals.
