Single row conical roller Du bearings are the most commonly used conical roller bearings.In recent years, Zhi has also used small-sized Dao double-row conical roller bearings in the front wheel hub of cars.Four-row conical roller bearings are used in heavy-duty machines such as large cold and hot rolling mills.

Single-row conical roller bearings have an outer ring with an inner ring and a set of conical rollers enclosed in an inner ring component by a basket holder.The outer ring can be separated from the inner ring assembly. According to the ISO Conical Roller Bearing Shape Size Standard, the outer ring or inner ring assembly of any standard type of conical roller bearing should be internationally interchangeable with the same type of outer ring or inner ring assembly.That is, the outer ring of the same type must meet the requirements of ISO492 (GB307) in addition to the outer dimensions and tolerances, the conical angle of inner ring components, the cone diameter of components, etc. must also conform to the relevant provisions of interchange.

Generally, the conical angle of the outer ring raceway of a single-row conical roller bearing can withstand both the radial and the directional loads of the bearing before the conical angle is between 10 and 19 degrees.The larger the cone angle, the greater the ability to withstand the axial load.Bearing with large conical angle, with rear code plus B and conical angle between 25 and 29 degrees, can withstand large axial load.In addition, single-row conical roller bearings can adjust the clearance size during installation.

The outer (or inner) ring of a double-row conical roller bearing is a whole.The small end faces of the two inner rings (or outer rings) are similar, with a diaphragm in the middle, and the clearance is adjusted by the thickness of the diaphragm, or by the thickness of the diaphragm, the pre-overload of the double-row conical roller bearing can be adjusted.

Tapered roller bearings mainly bear combined radial and axial loads.Bearing bearing capacity depends on the raceway angle of the outer ring, the larger the angle, the larger the bearing capacity.This type of bearing is a separate bearing, which is divided into single-column, double-column and four-column conical roller bearings according to the number of columns of the rollers in the bearing.Single-row tapered roller bearing clearance requires user adjustment during installation; double-column and four-column tapered roller bearing clearance has been given at the time of product shipment according to user requirements without user adjustment.

Tapered roller bearings have conical raceways with inner and outer rings arranged in between.All projection lines on the conical surface meet at the same point on the axis of the bearing.This design makes conical roller bearings particularly suitable for composite (radial and axial) loads.The axial load capacity of bearings is largely determined by the contact angle alpha; the larger the angle alpha, the higher the axial load capacity.Angle size is expressed by the calculation factor e; the larger the e value, the larger the contact angle, the greater the suitability of bearing to withstand axial load.

Tapered roller bearings are usually segregated, that is, conical inner ring components consisting of inner rings with rollers and retainer components can be mounted separately from the conical outer rings (outer rings).
