Tapered roller bearings are mainly bears radial, axial joint load radial based. Racewayangle bearing capacity depends on the outer ring of the bearing capacity, the larger the angle the greater. This kind of bearing is separable bearings, roller bearings according to the number of rows into a single row, double row and four row taperedroller bearing. Single row tapered roller bearing clearance required user adjustmentwhen in installation; double row and four row tapered roller bearing clearance has been in the factory according to user requirements given, the user does not have to adjust.

Tapered roller bearings with tapered inner and outer ring raceway, tapered roller are arranged in between. All lines of conical surface projection at the same meet the bearing axis. This design makes the tapered roller bearings are particularly suitable to withstand complex (radial and axial load). Axial load bearing capacity is largely determined by the contact angle; alpha angle is larger, the axial load capacity is higher. Angle by calculating coefficients of e to say; the bigger the E value, the contact angle the greater the axial load is bigger.

Tapered roller bearings are usually separated type, namely the cone assembly with roller and cage assembly composed of conical outer ring and inner ring can beinstalled separately (outer ring).

Tapered roller bearings are widely used in cars, rolling mill, mine, metallurgy, plasticsmachinery industry.
