Bearing the specific classification

Time:2016-06-27 15:23:15  From:Website    Back

According to the loading direction can be divided into: (1) the radial humanistic bearing, also called radial bearing, bear radial load. (2) the thrust bearing, say again thrust bearing, bear axial load. (3) radial thrust bearing, also called radial thrust bearing, and at the same time, bear radial load and axial load. Work according to the bearing friction properties can be divided into sliding friction bearing (hereinafter referred to as sliding bearing) and rolling friction bearing (hereinafter referred to as rolling bearing) two kinds big.
Deep groove ball bearing
The most representative rolling bearing, wide range of USES
Can bear radial load and two-way axial load
It is applicable to high-speed rotating and requirements of low noise, low vibration occasions
With steel plate dust cover or rubber sealing ring seal type Harbin bearing inner advance filling the right amount of grease’s outer ring has anti-rotation ring or flange bearing, namely easy to axial positioning, and convenient for the installation of the enclosure
Maximum duty bearing size and standard bearing the same, but the inner and outer one place filling tank, increase the loading ball number and improve the rated negative.
The main applicable cage: steel plate stamping cage (waveform, crown... single row; S shape... double column)
Copper alloy or phenolic resin cutting cage, synthetic resin forming cage
Main application: car: rear wheel, gear boxes, electrical installation components
Electrical: general motor, household electrical appliances
Other: instrument, internal combustion engine, construction machinery, railway vehicle, loading and unloading handling machinery, agricultural machinery, all kinds of industrial machinery
Angular contact ball bearing
Ring and ball between contact Angle, the standard contact Angle is 15 ° and 30 ° and °The greater the Angle of contact axial load capacity is bigger also Contact Angle is smaller, the better the high speed rotating Single row bearing can bear radial load and unilateral axial load DB combination, DF combination and double bearing can bear radial load and two-way axial load DT combination suitable unilateral axial load is bigger, a single bearing rated load shortage situation High speed with ACH type bearing ball diameter small, ball number, mostly used for machine tool spindle Angular contact ball SKF bearing is suitable for high speed and high precision rotary The structure for the combination of the two single row angular contact ball bearing common inner ring and outer race, can bear radial load and two-way axial load No filling tank bearing also have sealed typeThe main applicable cage: steel plate stamping cage (bowl... single row; S form, crown... double column) Copper alloy or phenolic resin cutting cage, synthetic resin forming cage Main application: single row: machine tool spindle, high frequency motor, gas turbine, centrifugal separator, small car wheel, differential pinion shaf Double: oil pump, roots blower, air compressor, all kinds of transmission, fuel injection pump, printing machines Four contact ball FAG bearing can bear radial load and two-way axial load A single bearing can replace positive combination on the back or combination of angular contact ball bearing Applicable to inherit pure axial load or axial load component large synthetic load This kind of bearing bear any direction axial load can form one of the contact Angle (alpha, so ring and ball always in a contact line double dealing point contact The main applicable cage: copper alloy cutting cage Main use: the plane jet engines, gas turbine Self-aligning ball bearing
Due to the outer raceway hand deliver spherical, with self-aligning properties, so it can automatic adjustment for shaft or shell of deflection or different heart is caused by the axis Cone hole bearing through the use of fasteners can easily installed in shaft Steel plate stamping cage: chrysanthemum form... 12, 13, 22... 2 rs, and... 2 rs Kwai form... 22, 23 Woodworking machinery, textile machinery transmission shaft, vertical set-contained self-aligning bearing Cylindrical roller bearing

Cylindrical roller and roller way a line contact, radial load capacity, which is designed to withstand heavy loads and shock load, also suitable for high speed rotating N type and NU type can be axial movement, can adapt for thermal expansion or installation error caused by the shaft and housing relative position changes, the most adapt to used for free end bearing NJ type and NF type can bear a certain degree of unilateral axial load, NH type and NUP type can bear a certain degree of two-way axial load inner ring or their cups are separable for easy loading and NNU type and NN type resistance to radial load strong rigidity, mostly used for machine tool spindle
The main applicable cage: steel plate stamping cage (Z), copper alloy cutting cage, pin type cage, synthetic resin forming cage
Main application: medium and large motor, generator, internal combustion engines, gas turbine, machine tool spindle, speed reducer, loading and unloading handling machinery, all kinds of industrial machinery
Entity type needle roller bearing
Have the basic structure of bearing inner ring and NU type cylindrical roller bearing the same, but because the needle, the volume can be reduced, and can withstand large radial load without inner ring of bearing the has an appropriate precision and hardness of the shaft installation surface as raceway surface use
The main applicable cage: steel plate stamping cage
Main application: automobile engine, transmission, pump, excavator crawler wheel, hoist, bridge crane, compressor
Tapered roller bearing
This kind of bearing with frustum of a cone shape roller, roller by inside circle big guard guide
Design makes the inner ring raceway surface and outer raceway surface and roller rolling the each cone vertex intersection in the bearing center online point
Single row bearing can bear radial load and unilateral axial load, double bearing can bear radial load and two-way axial load
Applicable to withstand heavy loads and shock load
According to the contact chest (alpha different, divided into small cone Angle, the cone Angle and the big cone Angle three type, the greater the contact Angle axial load capacity is bigger also
Outside and internal components (inner ring and roller and cage components) separable, easy to put down
Rear auxiliary code "J" or "JR" bearing with international compatibility
This kind of bearing has many use English series products
The main applicable cage: stamping steel cage, synthetic resin forming cage, pin type cage
Main application: car: front, rear wheel, transmission and differential pinion shaft. Machine tool spindle, construction machinery, large agricultural machinery, railway vehicle gear reducer, mill roll neck and reduction gear.
