1.Angular Contact Ball Bearing
Angular contact ball bearings are designed with a contact angle between the ring and the ball. The standard angles are 15°, 30°, and 40°. A larger contact angle results in a greater axial load capacity, while a smaller angle facilitates high-speed rotation. A single row can handle radial loads and one-way axial loads, and two single-row bearings combined can handle radial loads and two-way axial loads.
Uses: machine tool spindle, high-frequency motor, gas turbine, centrifuge, small car front wheel, differential pinion shaft.
2.Aligning Ball Bearing
Aligning ball bearings consist of double rows of steel balls and an inner spherical outer ring raceway. This design allows for automatic adjustment of shaft deflection or misalignment, and they primarily bear radial loads.
Applications: woodworking machinery, textile machinery drive shaft, vertical aligning bearing with seat.
3.Aligning Roller Bearing
Aligning roller bearings have spherical rollers between the outer spherical raceway ring and the inner double raceway ring. They come in four types - R, RH, RHA, and SR - and have aligning performance, capable of automatically correcting axis errors caused by shaft or shell deflection or misalignment. They can handle radial loads and two-way axial loads.
Applications: papermaking machinery, reduction gear, railway vehicle axle, rolling machine gear box seat, rolling machine roller, crusher, vibrating screen, printing machinery, woodworking machinery, industrial reduction gear, vertical aligning bearing with seat.
4.Thrust Aligning Roller Bearing
Thrust aligning roller bearings have spherical rollers arranged at an angle, with aligning performance due to the spherical raceway surface of the seat. They can handle a significant amount of axial load and a limited amount of radial load, and use oil lubrication.
Applications: hydraulic generator, vertical motor, ship propeller shaft, rolling screw reducer, tower crane, coal mill, extruder, forming machine.
5.Tapered Roller Bearing
Tapered roller bearings consist of circular table rollers, guided by the inner ring's large guard edge. The raceway surfaces of the inner ring and outer ring and the cone surface of the rollers intersect at a point on the bearing center line. Single-row bearings can handle radial and one-way axial loads, while double-row bearings can handle radial and two-way axial loads, making them suitable for heavy and impact loads.
Applications: Automobile: front wheel, rear wheel, transmission, differential pinion shaft. Machine tool spindle, construction machinery, large agricultural machinery, railway vehicle gear reduction device, rolling mill neck and reduction device.
6.Deep Groove Ball Bearings
Deep groove ball bearings have continuous groove raceways in each ring, with a cross-section that makes up about one-third of the equatorial circumference of the ball. They mainly handle radial loads but can also handle a limited amount of axial load. With an increased radial clearance, they can handle axial loads alternating in two directions. They have low friction coefficients, high limit speeds, and high precision, making them the preferred choice for users.
Applications: automobile, tractor, machine tool, motor, water pump, agricultural machinery, textile machinery, etc.
7.Thrust Ball Bearing
Thrust ball bearings consist of a washer-shaped raceway ring with a raceway, ball and cage assembly. The raceway ring matching the shaft is referred to as the shaft ring, while the raceway ring matching the shell is called the seat ring. Two-way bearings are matched with a middle ring
Angular Contact Ball Bearings:
These bearings are used to support radial and axial loads. They have lower friction and better speed and alignment capabilities compared to other types of bearings. Applications include hydraulic generators and crane hooks.
8.Thrust Roller Bearings:
These bearings are designed to support axial loads, with a maximum of 55% of the load being meridional. The asymmetrical spherical roller of type 29000 reduces relative sliding between the stick and raceway, resulting in lower friction, high speed, and better alignment. The long, large diameter roller with a large number of rollers provides high load capacity and is usually lubricated with oil, with low speeds lubricated by grease. Applications include crane hooks and hydraulic generators.
9.Cylindrical Roller Bearings:
These bearings consist of a roller guided by two bearing rings, with the cage roller and guide ring forming a component that can be separated from another bearing ring. They are easy to install and disassemble, especially when the inner and outer rings need to fit with a shaft and shell. Cylindrical roller bearings are mainly used to support radial loads, with single row bearings capable of supporting small steady axial loads or large intermittent axial loads. Applications include large motors, machine tool spindles, axle boxes, diesel crankshafts, automobiles, and gearboxes.
10.Four Point Contact Ball Bearings:
These bearings support radial loads and two-way axial loads. They can replace the front or back combination of angular contact ball bearings and are suitable for bearing pure axial loads or larger axial load components. The ring and ball form three-point contact, allowing these bearings to support axial loads in any direction. Applications include aircraft jet engines and gas turbines.
11.Thrust Cylindrical Roller Bearings:
These bearings are composed of a washer-shaped raceway ring, cylindrical roller, and cage assembly. The cylindrical roller has a convex surface, ensuring uniform pressure distribution between the roller and raceway surface. They can support one-way axial loads and have high axial rigidity. Applications include oil drilling machines and iron and steel making machinery.
12.Thrust Needle Roller Bearings:
These separable bearings consist of a raceway ring with needle roller and cage assembly, while non-separated bearings are integral bearings composed of raceway rings, needle roller, and cage components. They support one-way axial loads and are compact, making them suitable for use in compact machinery designs. Applications include automobiles, cultivators, and machine tools.
13.Thrust Tapered Roller Bearings:
These bearings consist of a circular table roller guided by a raceway ring and guard edge. The shaft ring, seat ring, and roller's cone surface intersect at a point on the bearing centerline, allowing for one-way or two-way axial load support. Applications for one-way bearings include crane hooks and oil rig rings, while bidirectional applications include roller necks.
14.Outer Spherical Ball Bearings with Seat:
These bearings consist of a spherical ball bearing with seals on both sides and a cast or stamped steel bearing seat. The inner structure is the same as a deep groove ball bearing, but the inner ring is wider than the outer ring and has a truncated spherical outer surface. This allows for automatic alignment when matched with the concave spherical surface of the bearing seat. Applications include mining, metallurgy, agriculture, chemical industry, textiles, printing and dyeing, and conveying machinery.
