246x313x33mm BA246-2A Bearing Single Row Excavator Slewing Bearing For Construction Excavator
BA246 2A Slewing Bearing 246×313×33mm For Construction Excavators
Basic Parameters
Type and Structure
A single-row ball slewing bearing composed of inner ring, outer ring, rolling elements (steel balls), and cage, featuring a high-rigidity and low-friction design. In the model, "246" corresponds to an inner diameter of 246mm, and "2A" indicates a double-row sealed or reinforced structure.
Dimensional Parameters
Inner diameter:246mm
Outer diameter:313mm
Thickness:33mm
Suitable for compact space requirements and capable of high-load transmission.
Material and Process
Made of high-carbon chromium bearing steel (e.g., GCr15), subjected to quenching and tempering. Surface hardness reaches HRC58-62, with wear-resistant and impact-resistant properties. Raceway precision is above class P5, surface roughness Ra≤0.1μm, and friction coefficient ≤0.0015.
