The structure of Koyo tapered roller bearings mainly includes an outer ring, an inner ring, a rolling body (roller) and a cage. The rolling element is located between the inner ring and the outer ring and is kept in the specified axial position by the cage. The contact Angle between the inner ring and the outer ring is generally between 10° and 30°, and different contact angles will affect the bearing capacity and speed limit.

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 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.

Koyo tapered roller bearings are suitable for applications requiring simultaneous radial and axial loads, such as differential, hub, transmission and other components of automobiles, as well as wind turbines, agricultural machinery, construction machinery and other equipment requiring high load capacity and high rotation accuracy. 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 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.

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.

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:     

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.

Railway Axle BearingsAxle bearings: tapered roller bearings, tapered roller bearing boxes, cylindrical roller bearings, spherical roller bearings. Railway axle bearings can be subjected to high shocks and loads. Mounting space is also limited, so in many cases compact, double-row bearings with high load ratings are used.Railway Axle Box BearingAxlebox bearings should have a large load carrying capacity, be able to resist shock vibration, and must have a high life expectancy, safety and reliability, smaller size and quality.

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.

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

Spruce develops and supplies a wide range of axles, drive units and traction motor bearings for railway rolling stock. These bearings feature high performance, high reliability and long-term maintenance-free service to support railway companies in providing fast, safe and reliable transport.Axle bearings: tapered roller bearings, tapered roller bearing cartridge, cylindrical roller bearings, spherical roller bearings.Railway axle bearings are subjected to heavy impacts and loads.

UBC tapered roller bearing is a kind of rolling bearing with tapered roller, the roller and raceway between the inner ring (cone hub) and the outer ring (cup) intersect at the cone half Angle on the outer surface of the cone, so that the bearing can bear a large load in the radial and axial direction. UBC tapered roller bearings usually include single row, double row and four row structures, which are widely used in automotive, mechanical equipment, aerospace and other fields.

1) Less coefficient of friction, High limiting speed, Large size range, Variations of structure.2) Tapered Roller Bearings are designed such like cup. Cone and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis.3) Single-row tapered roller bearing is able to carry radial and axial load in one directionssimultaneously because an axial component of produced when this type of bearings loadedradically, two bearings are used together facing one another, or two or more bearings arematched and used.

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

The main uses of conical roller bearings include the following aspects1. Construction machinery field: Conical roller bearings are widely used in all kinds of heavy construction machinery and equipment, such as excavators, loaders, bulldozers, road rollers, cranes, etc. These equipment need to withstand large axial load and radial load, and have high speed and accuracy requirements, cone roller bearings can meet these requirements to ensure the normal operation of the equipment.2.

Tapered curler bearing refers to the radial thrust kind rolling bearing whose rolling physique is a tapered roller. There are small cone angles and giant cone angles. The small cone Angle usually bears the radial and axial mixed hundreds ordinarily primarily based on radial loads, regularly used in double, reverse installation, the internal and outer seat rings can be established respectively, and the radial and axial clearance can be adjusted throughout set up and use.

Conical roller bearing is a common mechanical transmission element, mainly used to carry axial and radial loads and can achieve rotation and swing motion. It is mainly composed of an inner ring, an outer ring, a roller and a cage, with large carrying capacity, low friction, suitable for high-speed rotation and high accuracy requirements, so it is widely used in construction machinery, automotive, aerospace, mining machinery, metallurgical equipment and other fields.

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.
