Rolling Mill Used Four-row Taper Roller Bearing 381168 Bearing-manufacture,factory,supplier from China

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.

Iko is a well-known company specializing in the production of various types of bearing products, and its tapered roller bearings are one of its product series. Tapered roller bearing is a common type of bearing, mainly used in mechanical transmission fields, such as automotive, aerospace, engineering machinery and other fields.Iko tapered roller bearings have the following characteristics: First, the structural design is reasonable, mainly composed of inner ring, outer ring, roller and cage.

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

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.

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.

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

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

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.

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

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.

Cross roller bearing is a special kind of rolling bearing, which is widely used in mechanical field. It is designed to meet large size equipment that needs to operate under the requirements of high load capacity, high rigidity and high rotational accuracy. The cross roller bearing is composed of inner and outer rings, rollers, sealing rings and cages, and its structural advantages are that it can withstand both radial and axial loads, with high torque rigidity and running accuracy. The following will introduce the characteristics and applications of cross roller bearings in detail.

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 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

Bearing seat is a mechanical part for mounting bearings, which usually has two parts: a seat body fixed on the machine tool and a bearing seat sleeve fixed with the seat body. The role of the bearing seat is to support the bearing and ensure that the bearing can be correctly installed on the shaft of the machine equipment to withstand the load brought by the bearing in the rotating motion.The bearing seat is usually made of a high-strength metal or steel material to ensure that it has sufficient strength and stiffness to support the bearing.

(1)Linear motion bearing is a kind of low-cost metal for producing linear motion system, which is used for infinite stroke cylindrical shaft.. Because point contact ball bearing with shaft, so using the load is small.  (2) the flange linear bearing can be divided into: round flange type, method type, elliptical flange type, guided round flange, guiding method, guide the elliptical flange type, extended round flange type.(3)According to the specification is divided into two series of LM and LME series.
