Neutral - 3806/139.7/P5 | Four Row Tapered Roller Bearing | 139.70 × 200.02 × 157.16 mm

Details

Neutral 3806/139.7/P5 is a four row tapered roller bearing with inner diameter 139.70 mm, outer diameter 200.02 mm and width 157.16 mm. Additional specifications include bore type CYLINDRICAL, cage STANDARD and lubrication STANDARD.

These bearing is a specialized, large-scale four-row tapered roller bearing. This industrial-grade component is engineered primarily for heavy-duty metallurgy applications, such as rolling mills and oil drilling machinery. Standard single-row tapered alignments accept pure radial or single-direction axial loading vectors. This four-row consolidated architecture handles massive, multi-directional combination axial thrust and crushing radial pressures simultaneously. Material : Case-hardened 20Cr2Ni4A alloy steel (or premium GCr15 chrome steel) for an ultra-hard outer shell and shock-absorbing core. Features are : Logarithmic Roller Profile, Vibration Reduction, Low Heat Generation, Misalignment Tolerance, Integrated Spacer System, Enhanced Lubrication Paths, Superior Fatigue Limit Performance. Applications : Mining & Mineral Processing, Heavy Construction & Infrastructure Machinery, Renewable Energy Generation, Pulp & Paper Manufacturing, Aerospace & Defense Infrastructure. P5=Precision and Tolerance Class 5.
