L217849D Four Row Taper Roller Bearing L-manufacture,factory,supplier from China

Iko tapered roller bearings are also very convenient in terms of installation and maintenance.

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.

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

Tapered roller bearings are separate bearings. Both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single, double and four-row tapered roller bearings according to the number of rollers installed. Single-row tapered roller bearings can support radial loads and axial loads in one direction.The type code of tapered roller bearings is 30,000, and tapered roller bearings are separable bearings.

Single row tapered roller bearing is a common rolling bearing, which is composed of an inner ring, an outer ring, a roller and a cage. Its structure is similar to a conical shape, which is why it gets its name.The contact points on the inner and outer rings are conical and suitable for bearing large loads in both radial and axial directions.

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

Railway shaft double row tapered roller bearings have the following characteristics:High load bearing capacity: Double row tapered roller bearings are designed with two rows of rollers, so they can withstand large radial and axial loads.High temperature resistance: suitable for high-speed operation and high temperature environment, with good heat resistance.Strong aligning ability: can maintain good working performance when bearing installation is not accurate or axial displacement.Easy assembly and disassembly: double row tapered roller bearing structure is relatively simple, easy disassembly

Slewing bearing has four series of toothless, external and internal toothed four-point contact ball bearings, double row angular contact ball bearings cross cylindrical roller bearings, cross tapered roller bearings and three row cylindrical roller composite bearings, of which four-point contact ball bearings have higher static load capacity, cross cylindrical roller has higher dynamic load capacity, The pre-interference of cross-tapered roller bearing can make the bearing have greater support rigidity and rotation accuracy.

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.

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.

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.

Double-row tapered roller bearings are usually used in applications that require large loads and high-speed rotation, such as wind turbines, metallurgical equipment, rolling mills and heavy machinery, etc.

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 important construction modes of the turntable bearing seat are: four-point contact ball bearing seat, double-row angular contact thrust ball bearing seat, interpenetrating cylindrical roller bearing seat, interpenetrating tapered roller bearing seat, and three-row cylindrical roller with turntable bearing seat.According to whether the gear can be carried and the spread of the gear is divided into: toothless, external or internal gear and other different structures.The four-point contact ball turntable bearing seat has a higher static bearing capacity, the interspersed cylindrical roller be

The advantages of UBC tapered roller bearings include large bearing capacity, high rotation accuracy, wear resistance, smooth operation and so on. The inner ring and outer ring can adjust the axial position by adjusting the bearing clearance, so that it is more convenient in the installation and use process.

Railway bearing is a kind of application in railway bearing, wheel bearing railway locomotive vehicle shaft systems with different application conditions with different structural design, locomotives, passenger car axle box, bearing through the axle box connected to the bogie, railway wagon axle box, bearing with bogie side frame connected by load-bearing saddle bearing wheel and impact load between the bogie frame, and more Corners is under the axial load of wheel bearing structure contains a cylindrical roller bearing, cylindrical roller bearing unit, taper roller bearing, tapered roller bea

The raceway with the inclination Angle enables the tapered roller bearing to bear the combined radial and axial loads. The greater the Angle between the outer raceway and the bearing center line, the greater the ability to withstand the axial and radial load ratio. The linear contact between the roller and the raceway makes the tapered roller bearing have a great load bearing capacity. This feature and the ability to withstand radial loads, axial loads and both combined loads make tapered roller bearings ideal for many applications.

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.

The sealing and protection of truck bearings are also very important. Trucks often drive in a variety of harsh road conditions, bearing in dust, water vapor and chemicals and other corrosive environment. In order to extend the life of the bearing, it is necessary to take into account the sealing property in the design, and select the appropriate sealing material and structure.Truck bearings also have certain requirements on installation and maintenance. Proper installation and proper lubrication are the keys to ensure the normal operation of truck bearings.
