Tapered roller bearing 32012/32013/32014/32015/32016/32017/32018/32019
● Tapered roller bearings are separable bearings.
● It can be easily mounted on the journal and bearing pedestal.
● It can withstand an axial load in one direction.And it can limit the axial displacement of the shaft relative to the bearing seat in one direction.
-
Tapered Roller Bearings
● Are separable bearings with tapered raceway in the inner and outer rings of the bearings.
● Can be divided into single row, double row and four row tapered roller bearings according to the number of rollers loaded.
-
Single Row Tapered Roller Bearings
● Single row tapered roller bearings are separable bearings.
● It can be easily mounted on the journal and bearing pedestal.
● It can withstand an axial load in one direction. And it can limit the axial displacement of the shaft relative to the bearing seat in one direction.
● Widely used in automobile, mining, metallurgy, plastic machinery and other industries.
-
Double Row Tapered Roller Bearings
● Double row tapered roller bearings are of various construction
● While bearing radial load, it can bear bidirectional axial load
● Radial and axial combined loads and torque loads, which are mainly capable of bearing large radial loads, are mainly used in components that limit the axial displacement in both directions of the shaft and housing
● Suitable for applications with high rigidity requirements. Widely used in the front wheel hub of a car
-
Four-Row Tapered Roller Bearings
● Four-row tapered roller bearings have a wide range
● Simplified installation due to fewer components
● The load distribution of four-row rollers is improved to reduce wear and prolong service life
● Due to the reduction of inner ring width tolerance, the axial positioning on the roll neck is simplified
● The dimensions are the same as those of conventional four-row tapered roller bearings with intermediate rings
-
Cylindrical Roller Bearing
● The internal structure of cylindrical roller bearings adopts the roller to be arranged in parallel, and the spacer retainer or isolation block is installed between the rollers, which can prevent the inclination of the rollers or the friction between the rollers, and effectively prevent the increase of rotating torque.
● Large load capacity, mainly bearing radial load.
● Large radial bearing capacity, suitable for heavy load and impact load.
● Low friction coefficient, suitable for high speed.
-
Single Row Cylindrical Roller Bearings
● Single row cylindrical roller bearing only by radial force, good rigidity, impact resistance.
● It is suitable for short shafts with rigid supports, shafts with axial displacement caused by thermal elongation, and machine accessories with detachable bearings for installation and disassembly.
● It is mainly used for large motor, machine tool spindle, engine front and rear supporting shaft, train and passenger car axle supporting shaft, diesel engine crankshaft, automobile tractor gearbox, etc.
-
Double Row Cylindrical Roller Bearings
●Has cylindrical inner hole and conical inner hole two structures.
●Has the advantages of compact structure, large rigidity, large bearing capacity and small deformation after bearing load.
●Can also adjust the clearance slightly and simplify the structure of the positioning device for easy installation and disassembly.
-
Four-Row Cylindrical Roller Bearings
● Four row cylindrical roller bearings have low friction and are suitable for high speed rotation.
● Large load capacity, mainly bearing radial load.
● It is mainly used in the machinery of rolling mill such as cold mill, hot mill and billet mill, etc.
● The bearing is of separated structure, bearing ring and rolling body components can be conveniently separated, therefore, the cleaning, inspection, installation and disassembly of the bearing are very convenient.
-
Spherical Roller Bearings
● Spherical roller bearings have automatic self-aligning performance
● In addition to bearing radial load, it can also bear bidirectional axial load, can not bear pure axial load
● It has good impact resistance
● Suitable for installation error or deflection of the shaft caused by Angle error occasions
-
Needle Roller Bearings
● Needle roller bearing has large bearing capacity
● Low friction coefficient, high transmission efficiency
● High load bearing capacity
● Smaller cross section
● The inner diameter size and load capacity are the same as other types of bearings, and the outer diameter is the smallest
-
Needle Roller Thrust Bearings
● It has a thrust effect
● Axial load
● Speed is low
● You can have deflection
● Application: machine tools cars and light trucks trucks, trailers and buses on two and three wheels
