Product Description
Imported bearings are a concept contrasted with Chinese-made bearings. Imported bearings not only provide strong brand support, advanced scientific concepts and innovation, but also perfect after-sales service and strong expansion of product range.
Well-known brands of imported bearings include: SKF, FAG, IKO, INA, NSK, NTN and others.
Characteristics
1. Design and performance characteristics of tapered roller thrust bearings
In thrust tapered roller bearings, the rolling elements are tapered rollers. Due to the fact that the rollers and the raceways of the thrust bearing rings converge at one point on the bearing axis, the rolling surfaces can provide clean rolling, and their maximum rotation speed is higher than that of cylindrical roller thrust bearings.
Tapered roller thrust bearings are capable of supporting one-way axial loads.
The designation of the type of thrust tapered roller bearings is 90000.
Due to the small volume of production of thrust tapered roller bearings, most of the models produced have non-standard overall dimensions, and series and standard sizes with standard overall dimensions are produced in limited quantities. Therefore, at present there is no national standard for the overall dimensions of bearings of this type.
2. Design and performance characteristics of thrust angular contact ball bearings
Thrust angular contact ball bearings typically have a contact angle of 60°. The most commonly used thrust angular contact ball bearings are usually double-sided. They are primarily used in precision machine tool spindles, usually in combination with double row cylindrical roller bearings. They can bear double-sided axial loads and have the advantages of high precision, good rigidity, low heating, high rotation speed, and easy installation and disassembly.
3. Design and performance characteristics of double row tapered roller bearings
Double row tapered roller bearings come in a variety of designs. The most common is the 35000 type, which consists of an outer ring with two raceways and two inner rings, between which a spacer ring is installed. Changing the thickness of the spacer ring allows you to adjust the gap. This type of bearings is capable of supporting radial loads and simultaneously bilateral axial loads, as well as limiting the axial displacement of the shaft and housing within the axial clearance of the bearing.
4. Design features of tapered roller bearings
The symbol for the type of tapered roller bearings is 30000. Tapered roller bearings are split bearings. In general, especially within the size range provided for by GB/T 307.1-94 “Rolling bearings. Radial bearings. Tolerances, outer rings and inner assemblies of tapered roller bearings are completely interchangeable. The outer ring angle and outer race diameter, along with the overall dimensions, are standardized. Changing these parameters during design or manufacturing is not permitted. This makes the outer rings and inner assemblies of tapered roller bearings interchangeable worldwide.
Tapered roller bearings are primarily designed to carry combined radial and axial loads with a predominant radial component. Compared to angular contact ball bearings, they have a higher load capacity, but a lower maximum rotation speed. Tapered roller bearings are capable of supporting axial loads in one direction and limiting the axial displacement of a shaft or housing in one direction.
5. Features of deep groove ball bearings
Structurally, each deep groove ball bearing ring has a continuous grooved raceway whose cross-section is approximately one-third the circumference of the ball's center. Deep groove ball bearings are primarily used to carry radial loads, but can also carry certain axial loads. As the radial clearance in the bearing increases, they acquire the properties of angular contact ball bearings and can absorb alternating axial loads in both directions. Compared with other types of bearings of similar sizes, these bearings have low friction coefficient, high limiting speed and high precision, making them the preferred type for consumers to choose. Deep groove ball bearings have a simple structure and are easy to operate. This is the most popular and widely used type of bearings.
