The selection of suitable Koyo tapered roller bearings can improve the efficiency and reliability of machine equipment, reduce maintenance work and costs, and is an important bearing product widely used in various fields.

Tapered roller bearings are a type of bearing widely used in industrial fields. In the industry, tapered roller bearings are mainly used in machinery and automobiles, such as pharmaceutical equipment, hydraulic machinery, machine tools, automotive differentials, etc. These mechanical equipment are used in a mix of dynamic and static loads, there are different friction factors in the environment.

Tapered roller bearings are widely used in various mechanical fields, such as automobiles, aviation, machine tools, etc., because of its large bearing capacity, high precision, good reliability and other advantages, it has been widely concerned and applied in the industrial field.

Koyo tapered roller bearing is a common rolling bearing, usually used in automobiles, mechanical equipment, wind turbines and other fields.

Tapered roller bearings are separated bearings, and the inner and outer rings of the bearings are equipped with tapered raceways. This kind of bearing is divided into single row, double row and four row tapered roller bearings and other different structural types according to the number of rows of rollers installed. Single-row tapered roller bearings can withstand radial loads and axial loads in a single direction.

The range of four-row tapered roller bearings is wide, including not only the traditional design with an intermediate ring between the outer ring and/or the inner ring, but also the modification of the four-row tapered roller bearings with an integrated middle ring and the bearing ring.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter (mm)Width(mm)Cr(kN)Cor(kN)Grease lubrication speed (r/min)Oil lubrication speed (r/min)Weight (kg)302027202E15351114.913.412000160000.053302037203E17401220.821.89000120000.079302047204E20471428.230.58000100000.126302057205E25521532.2377000900

As one of the largest taper roller manufacturers in Shandong, China, in addition to the tapered roller bearings introduced above, we can also provide the following tapered roller types.

NTN tapered roller bearings are mainly used to bear radial and axial combined loads mainly based on radial loads, with high stiffness and rotation accuracy, and have large bearing capacity and low limit speed compared with angular contact ball bearings. Its carrying capacity depends on the Angle of the raceway of the outer ring, and the greater the Angle, the greater the carrying capacity.

Four row tapered roller bearings are mainly used for work rolls, support rolls, and billet breakers of various plate and strip rolling mills. The clearance of the bearing is changed by adjusting the thickness of the spacer to make it more suitable for the working condition.1. Strong bearing capacity: four row tapered roller bearings can withstand greater loads under the same size, because it is shared by multiple rollers, so it has higher carrying capacity and better distribution performance.2.

A double-row tapered roller bearing is a common bearing type that consists of two tapered rollers mounted on an inner ring and an outer ring. It can withstand large radial and axial loads and is able to maintain high accuracy and stiffness while rotating at high speeds.Double row tapered roller bearings are designed so that the inner and outer rings can be adjusted separately to achieve axial and radial preloading.

Thrust tapered roller bearings can form a very compact bearing configuration, which can withstand very heavy axial loads, is not sensitive to impact loads, and has good rigidity. LYTBZ produces unidirectional tapered roller bearings and bidirectional tapered roller thrust bearings. The screw fixed bearing constitutes a specially designed unidirectional tapered roller thrust bearing and is filled with rollers.Thrust tapered roller bearing features:This bearing is used for rolling mill screw fixed bearing configuration.

The working principle of Koyo tapered roller bearings is to use the rolling body to roll between the inner and outer rings, thereby reducing the contact area and reducing friction resistance. When the external radial or axial load is applied, the roller will bear the load between the inner and outer rings to achieve the function of supporting and transferring the load of the bearing. Rollers are designed so that they can equally share load when rotating, reduce local stress and extend service life.

Inch taper/tapered roller bearings belong to separable bearing, as the outer ring, also called cup, is separable and easy for assembly.

Iko tapered roller bearings have high load bearing capacity and wear resistance. Because of the conical roller design, the bearing can share the load evenly when bearing heavy loads, and the bearing capacity is effectively improved. At the same time, the use of high-quality materials and advanced manufacturing technology to ensure the bearing's wear resistance and extend the service life.Iko tapered roller bearings have high rotation accuracy and running stability.

A single-row tapered roller bearing has an outer ring, and its inner ring and a group of tapered rollers are enclosed by a basket cage into an inner ring assembly, and the outer ring and the inner ring assembly can be separated. In addition, single-row tapered roller bearings can adjust the size of the clearance during installation.

Tapered roller bearings are suitable for bearing radial loads, unidirectional axial loads and radial and axial combined loads. The axial load capacity of tapered roller bearings depends on the contact Angle α, that is, the Angle of the outer ring raceway, the greater the contact Angle α, the greater the axial load capacity. Generally tapered roller bearings do not allow Angle errors, but the surface of the roller and raceway can be specially designed to allow 2'~4' Angle errors.

In engineering applications, rotary support bearings play an important role. For example, in construction machinery, rotary support bearings are widely used in cranes, tower cranes, excavators and other equipment to support and rotate various arms, booms and rotating seats to ensure smooth operation and accurate positioning of equipment. In ships and port machinery, rotary support bearings are used to support various rotating devices to help ships navigate and cargo handling.

High load carrying capacity    The cage bars are displaced relative to the roller pitch diameter to enable the rollers to be placed closer to each other, creating room for additional rollers  High stiffness    The increased number of rollers increases radial stiffness.    High speed capabilityThe cage designs are suitable for high speeds, rapid accelerations and peak loads.  Long service life  The black oxide coating of rings and rollers (designation suffix L4B) contributes to extended service life by improving:     

Rotary support bearings are widely used in various mechanical equipment and construction machinery, such as cranes, rotary tables, machine tools, wind power equipment, drilling RIGS, excavators and so on. In these equipment, the rotary support bearing assumes the important role of supporting the rotating member, ensuring the normal operation of the equipment. At the same time, it is also widely used in high-end fields such as aerospace, ocean engineering, and automated production lines.
