The larger the contact angle, the greater the axial load - bearing capacity. Single - row ones can bear radial load and single - direction axial load, and double - row ones can bear radial load and double - direction axial load.Single - row: Machine tool spindles, high - frequency motors, gas turbines, centrifugal separators, front wheels of small cars, differential pinion shafts.Double - row: Oil pumps, Roots blowers, air compressors, various transmissions, fuel injection pumps, printing machines.Self - Aligning Ball BearingWith two rows of steel balls, the outer - ring raceway is spherical, which can automatically adjust the axis misalignment caused by shaft or housing deflection or non - concentricity. Tapered - bore bearings can be easily installed on the shaft by using fasteners, mainly bearing radial loads.Wood - working machinery, textile machinery transmission shafts, vertical mounted self - aligning bearings.Spherical Roller BearingThere are spherical rollers between the spherical outer - ring raceway and the double - raceway inner ring. It has self - aligning performance, and can bear radial load and double - direction axial load.Paper - making machinery, reduction devices, railway vehicle axles, rolling mill gearbox seats, rolling mill roller tables, crushers, vibrating screens, printing machines, wood - working machinery, various industrial reducers, vertical mounted self - aligning bearings.Thrust Spherical Roller BearingThe spherical rollers are arranged obliquely, and the raceway surface of the ring is spherical, which has self - aligning performance. It has a very large axial load - bearing capacity and can also bear a certain radial load while bearing the axial load.Hydro - generators, vertical motors, propeller shafts of ships, reducers for rolling mill rolling screws, tower cranes, coal mills, extruders, forming machines.Tapered Roller BearingIt is equipped with conical rollers, which are guided by the large rib of the inner ring. Single - row bearings can bear radial load and single - direction axial load, and double - row bearings can bear radial load and double - direction axial load, suitable for bearing heavy loads and impact loads.Automobiles: Front wheels, rear wheels, transmissions, differential pinion shafts; machine tool spindles, construction machinery, large - scale agricultural machinery, railway vehicle gear reduction devices, rolling mill necks and reduction devices.Deep - Groove Ball BearingEach ring of the deep - groove ball bearing has a continuous groove - type raceway with a cross - section approximately one - third of the equatorial circumference of the ball. It mainly bears radial load and can also bear a certain axial load. When the radial clearance of the bearing is increased, it has the properties of an angular - contact ball bearing and can bear two - direction alternating axial loads.Automobiles, tractors, machine tools, motors, water pumps, agricultural machinery, textile machinery, etc.Thrust Ball BearingIt is composed of a washer - shaped raceway ring with a raceway, and a ball and cage assembly. The raceway ring matching with the shaft is called the shaft ring, and the raceway ring matching with the housing is called the seat ring. Single - direction bearings can bear single - direction axial load, and double - direction bearings can bear double - direction axial load ( neither can bear radial load ).Automobile steering knuckles, machine tool spindles.Thrust Roller BearingIt is used for shafts that mainly bear axial load and combined radial load, but the radial load shall not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has a lower friction coefficient, a higher rotational speed, and has self - aligning ability.Hydro - generators, crane hooks.Cylindrical Roller BearingThe rollers are usually guided by the two ribs of one bearing ring, and the cage, rollers and guiding ring form an assembly, which can be separated from the other bearing ring, belonging to a separable bearing. Generally, it is only used to bear radial load. Only single - row bearings with ribs on both the inner and outer rings can bear a small constant axial load or a large intermittent axial load.Large - scale motors, machine tool spindles, axle boxes, diesel engine crankshafts, automobile and tractor gearboxes, etc.Four - Point Contact Ball BearingIt can bear radial load and double - direction axial load. A single bearing can replace the angular - contact ball bearings in front - combination or back - combination, and is suitable for bearing pure axial load or combined load with a large axial load component.Aircraft jet engines, gas turbines.Thrust Cylindrical Roller BearingIt is composed of a washer - shaped raceway ring ( shaft ring, seat ring ) and a cylindrical roller and cage assembly. The cylindrical rollers are convex - surface processed, so the pressure distribution between the rollers and the raceway surface is uniform, and it can bear single - direction axial load.Oil drilling rigs, iron and steel making machinery.Thrust Needle BearingThe separable type is composed of a raceway ring and a needle roller and cage assembly, which can be arbitrarily combined with a thin - walled raceway ring processed by stamping or a thick - walled raceway ring processed by cutting. The non - separable type is an integral bearing composed of a raceway ring processed by precision stamping and a needle roller and cage assembly, which can bear single - direction axial load.Speed change devices of automobiles, tractors, machine tools, etc.Thrust Tapered Roller BearingIt is equipped with conical rollers ( the large end is spherical ), and the rollers are accurately guided by the ribs of the raceway ring ( shaft ring, seat ring ). Single - direction bearings can bear single - direction axial load, and double - direction bearings can bear double - direction axial load.Single - direction: Crane hooks, rotary rings of oil drilling rigs.Double - direction: Rolling mill necks.Insert Ball BearingIt is composed of a two - side sealed insert ball bearing and a cast ( or steel plate stamped ) bearing seat. The inner structure of the insert ball bearing is the same as that of the deep - groove ball bearing, but the inner ring of this kind of bearing is wider than the outer ring, and the outer ring has a spherical outer surface, which can automatically align with the concave spherical surface of the bearing seat.Mining, metallurgy, agriculture, chemical industry, textile, printing and dyeing, conveying machinery, etc.Product Description Packaging & Shipping
