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. KMR 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 KMR single row tapered roller bearings,Following is the internal structure of KMR different product descriptions.B    Steeper contact angle than standard designCLN  Reduced tolerances for ring widths and total (abutment) width; corresponds to ISO tolerance class 6XCL0  Accuracy to ABMA tolerance class 0 for inch bearingsCL3     Accuracy to ABMA tolerance class 3 for inch bearingsCL7A  High-performance design for pinion bearing arrangements (superseded by CL7C)CL7C  High-performance design for pinion bearing arrangementsE       Enhanced design.
