Product Description
About the tapered roller bearings
Tapered roller bearings can be separated by the inner ring and roller, maintains a together make up components and outer ring can be installed separately. Roller and roll the contact point of the fixed way contact wires can reduce stress concentration.
Tapered roller bearings can withstand the big radial direction load and the axial load. Due to the circular cone roller bearings can only transfer one-way axial load, therefore, to transfer the opposite direction of the axial load will need another with the installation of symmetric circular cone roller bearings. Tapered roller bearings is the largest amount of single row circular cone roller bearings. In the front of the car wheel, recent years have used the small size of the double row circular cone roller bearings. Four row circular cone roller bearings used in large cold, ReGaJi and other heavy machine.
Features of Tapered Roller Bearings:
Single-row tapered roller bearings have an outer ring, and an inner ring assembly consisting of an inner ring and a group of tapered rollers embraced by the basket-shaped cage. The outer ring(cup) is separable from the inner ring assembly. According to standardized dimensions of tapered roller bearing specified by ISO, the outer ring or inner ring assembly of any tapered roller bearing with standardized dimension could make international exchange with the outer ring or inner ring assembly of the same series. That is to say, besides external dimensions, tolerances shall be in accordance with the provisions of the ISO492 (GB307), the cone angle of the inner ring assembly and cone diameter of assembly must also comply with the relevant provisions of the exchange.
Generally, when cone angle of outer ring raceway of single-row tapered roller bearings is from 10°to 19°, they could withstand axial loads and radial loads spontaneously. The big the cone angle, the larger the axial loads carrying capacity. Large-sized tapered roller bearings with post code plus B, the cone angle is from 25° to 29°, they carry large axial loads. In addition, single-row tapered roller bearings have the ability to adjust clearance during installation. The inner ring (or outer ring) of double row tapered roller bearings is a whole part. The small end face between two inner rings (or outer rings) is similar, there is one middle spacer ring between two inner rings, and the clearance is adjusted by thickness of spacer ring, which can also be used for adjusting the pre-interference of double row tapered roller bearings.
