• Structure and performance characteristics of double row tapered roller bearings

    The double row tapered roller bearing has many structures, and the large number is 35000 type. There is a double raceway outer ring and two inner rings. There is a spacer between the two inner rings, and the thickness of the spacer can be changed to adjust the clearance. These bearings are capable of withstanding biaxial axial loads while subjected to radial loads and limit axial displacement of the shaft and housing within the axial clearance of the bearing. www.nb-huayi.com read more

  • Structural features of tapered roller bearings

    The type of tapered roller bearing is 30,000, and the tapered roller bearing is a separate bearing. Under normal circumstances, especially in the size range of GB/T307.1-94 "Rolling bearing radial bearing tolerance", the outer diameter of the tapered roller bearing outer ring and the inner component are * universally interchangeable in use. The angle of the outer ring and the outer race diameter have been standardized as the outer dimensions. Changes are not allowed at the time of design and manufacture. So that the outer ring of the tapered roller bearing and the inner component can be univer... read more

  • What are the characteristics of deep groove ball bearings?

    Each ferrule of the structure deep groove ball bearing has a continuous grooved raceway having a cross-section of approximately one-third of the circumference of the equator of the ball. Deep groove ball bearings are mainly used to withstand radial loads and also withstand certain axial loads. When the radial clearance of the bearing is increased, it has the property of an angular contact ball bearing and can withstand the axial load alternating in two directions. Compared with other types of bearings of the same size, this type of bearing has a small friction coefficient, high speed limit and... read more

  • The nature of deep groove ball bearings

    Deep groove ball bearings are the most common type of rolling bearings. Deep groove ball bearings The basic deep groove ball bearings consist of an outer ring, an inner ring, a set of steel balls and a set of cages. The deep groove ball bearing types are single row and double row. The deep groove ball structure is also divided into two types: sealed and open. The open type refers to the bearing without sealing structure. The sealed deep groove ball is divided into dustproof seal and oil proof. seal. The dust seal cover material is stamped from steel plate, which is simple to prevent dust from ... read more

  • What are the causes of vibration damage of deep groove ball bearings (1)

    1. Partial damage: A small number of bearing raceways and rolling elements may be damaged due to handling or installation errors. In operation, rolling a damaged bearing component produces a specific vibration frequency. Vibration frequency analysis identifies damaged bearing components. This principle has been applied to condition monitoring equipment to detect damage to deep groove ball bearings. To calculate the bearing frequency, please refer to the calculation program "bearing frequency". www.nb-huayi.com read more

  • Clearance selection and ferrule processing of double row deep groove ball bearings (2)

    When selecting the double-row deep groove ball bearing clearance, first consider that the elastic tension of the double row deep groove ball bearing and the shaft and the casing hole will lead to the change of the bearing clearance value. Generally, the clearance value will be reduced after the bearing is installed; If the double row deep groove ball bearing is in the process of the mechanism, due to the different heat dissipation conditions of the shaft and the outer casing, a temperature difference between the inner ring and the outer ring will occur, which will result in a reduction in the ... read more
