Detailed Product Description

Definition of Tapered Roller Bearings
Tapered roller bearings can be separated from the inner ring and roller, cage together make up the components and the outer ring can be installed separately. Roller and raceway contact at the contact line can be modified to reduce stress concentration. Tapered roller bearings can support large radial load and axial load. As the tapered roller bearing can only pass one-way axial load, Therefore, in order to pass in the opposite direction of the axial load will need to install another with symmetrical tapered roller bearings.
Tapered roller bearings are single row in the largest amount of tapered roller bearings. In the car front wheel hub in recent years to spend the small size of the double-row tapered roller bearings. Four-row tapered roller bearings used in large-scale cold and hot-rolling mill and other heavy machines.
Single row tapered roller bearing has an outer ring, its inner ring and a set of tapered roller by a basket-shaped cage into an inner component inclusive. The outer ring and inner components can be separated, in accordance with ISO tapered roller bearings standard dimensions, any one standard model of tapered roller bearing outer ring or inner components and the same model should be able to outer or inner component to achieve an international exchange. The outer ring of the same model except that the Department of dimensions, tolerances required to comply with ISO492 (GB307) provided, the inner components of the cone angle, cone diameter and other components must also comply with the relevant provisions of the swap.
Typically, single row tapered roller bearing outer ring raceway of the cone angle is 10 ° ~ 19 ° prior to simultaneously withstand bearing loads and radial loads to the combined effects. Cone angle greater the ability to withstand greater axial load. Large cone angle of the bearing, post code plus B, cone angle 25 ° ~ 29 ° between, it can withstand a large axial load. In addition, the single row tapered roller bearings can be adjusted during the installation process clearance size.
Double-row tapered roller bearing outer ring (or inner) is a whole. Two inner (or outer) small-end close, with a gutter ring, clearance depends on every other ring to adjust the thickness, and can also be used to adjust the thickness of every other ring double row tapered roller bearings are pre-Interference.
Tapered roller bearings to bear the main radial-based radial and axial joint load. Bearing load capacity depends on the angle of the outer ring raceway, the greater the angle the greater the carrying capacity. Type of bearings is a separated type bearings, the rolling bearing body according to the number of rows into single row, double row and four row tapered roller bearings. Single row tapered roller bearing clearance required to install the user to adjust; double row and four row tapered roller bearing clearance in the factory based on user requirements for a given, do not need the user to adjust.
Tapered roller bearings have tapered inner and outer ring raceways, tapered rollers arranged in between. All conical surface of the projection lines of the same point in the bearing axis together. This design makes tapered roller bearings particularly suitable for bear compound (radial and axial) loads. The axial load bearing capacity of most of the decision by the contact angle α; α the angle the greater the higher the axial load capacity. Angle size of the computational coefficient e to represent; e larger the value, contact angle of larger bearings to withstand the application of axial load will be.
Tapered Roller Bearings are usually separated type, that is, with a roller and cage component of the inner components of the composition of the inner cone with tapered outer ring (outer ring) installed separately.
