Design features:
  Tapered Roller Bearing a conical inner and outer ring raceway, Tapered Roller arranged in between, all conical surface projection lines in the bearing axis to meet the same point, this design enables Tapered Roller Bearing particularly suited to bear composite (radial and axial) loads. Tapered Roller Bearings can best way to stress distribution in the Roller Raceway contact with the surface, thereby enhancing the reliability and affordability of error of perspective. LHB provides a wide range of sizes series of Tapered Roller Bearings, single row, matching single, double row, and four Tapered Roller Bearings can meet a wide range of applications.

We can produce the diameter from 15mm~360mm LHB single row tapered roller bearings,Following is the internal structure of LHB different product descriptions.
