Four-row tapered roller is a rolling bearing element with special structure and performance.
Double-row tapered roller bearings are a kind of bearings with inner and outer rings (refers to the two tapered surfaces) and diameter, keyway, keep frame and tapered roller.
Four-row tapered rollers are usually made of high-quality steel and have excellent load-carrying capacity. With their unique conical shape design, they are able to withstand combined radial and axial loads and play an important role in a variety of industrial fields.
Four-row tapered roller bearings have a wide range, including not only the traditional design with an intermediate ring between the outer ring and the inner ring, but also the modification of the intermediate ring and the bearing ring into a single-piece of these four-row tapered roller bearings without an intermediate ring. The specific advantages include the following points:
-Because it has fewer parts, it will be easier to install;
-The load distribution of the four rows of rollers is improved, which reduces the wear of the rollers and prolongs the service life of the bearing;
-The axial positioning on the roll journal is simplified due to the reduction of its inner ring width tolerance;
-its dimensions are the same as those of conventional four-row tapered roller bearings with intermediate rings.
Four rows of tapered roller bearings have important applications in the automotive industry, aerospace field, engineering machinery and iron and steel metallurgy industry, which can withstand high-speed rotation and large loads, play a role in supporting and transmitting power to ensure the normal operation of a variety of mechanical equipment.
Tapered roller bearing is a kind of bearing that can withstand complex loads and is characterized by high precision, high reliability and wear resistance. It consists of four parts, which are the inner ring, outer ring, roller and cage.
The inner ring and outer ring are conical with a certain oblique angle, capable of sharing axial and radial loads. The roller is conical, with the same bevel angle as the inner and outer rings, and can withstand axial and radial loads as it rotates. The cage holds the rollers in place so that they do not collide with each other.
Double-row roller bearings can withstand greater radial and axial loads than single-row roller bearings. The double-row roller design provides better stability and reduces bearing wobble and vibration during operation.
