Angular contact bearing installation precautions 1. Bearing installation should be performed in a dust-free and clean room. Bearings must be carefully selected. Bearing spacers must be ground. The parallelism of the spacers should be controlled at 1um while maintaining the same height of the inner and outer ring spacers. the following; 2. The bearing should be cleaned before installation. When cleaning, the inner ring slope is upward, the hand induction is flexible, and there is no stagnation. After drying, put in a specified amount of grease. 3. Special tools should be used for bearing installation, and the force should be uniform. Knocking is strictly prohibited; 4. The bearings should be stored clean and ventilated, without corrosive gas, and the relative humidity should not exceed 65%. Long-term storage should prevent rust regularly.

Enketo

La QJ206MA estas specifa tipo de Angula Kontakta pilka lagro. Jen rompo de ĝiaj ĉefaj trajtoj kaj specifoj:

1. Type of Bearing:

  • Angula Kontakta pilka lagro: Desegnita por trakti kombinitajn radialajn kaj aksajn ŝarĝojn, these bearings have contact angles that enable them to support higher axial loads compared to deep groove ball bearings. They are typically used in pairs or sets to accommodate loads in both directions.

2. Nomo de Lagro:

  • QJ206MA:
    • QJ: Indikas a four-point contact ball bearing, which is a type of angular contact bearing. It can handle axial loads in both directions and radial loads simultaneously.
    • 206: Specifas la grandecon de la lagro. La “2” indicates a light series, kaj “06” refers to the bore diameter (30 mm).
    • MA: Denotes the material or design specifics. “MAtypically means the bearing has a brass cage (retenero) and is designed for high-speed applications.

3. Dimensioj:

  • Bore Diametro (d): 30 mm
  • Ekstera Diametro (D): 62 mm
  • Larĝo (B): 16 mm

4. Ŝargi Taksojn:

  • Dinamika Ŝarĝo Takso (C): The maximum load the bearing can handle while rotating.
  • Statika Ŝarĝtakso (C0): The maximum load the bearing can handle while stationary.

(Exact load ratings depend on the manufacturer and should be verified from the product datasheet.)

5. Aplikoj:

  • Angular contact ball bearings like the QJ206MA are commonly used in:
    • Maŝinaj ilaj spindeloj
    • Pumpiloj
    • Rapidumujoj
    • Altrapidaj aplikoj
    • Applications requiring precise axial and radial load handling

6. Kaĝo Materialo:

  • La “MAsuffix indicates a brass cage, which is durable and suitable for high-speed operations.

7. Lubrication and Sealing:

  • Tipe, these bearings are lubricated with grease or oil. Sealing options (T.e., rubber seals or metal shields) may vary depending on the application.

8. Muntado:

  • Angular contact bearings are often mounted in pairs (dors-al-dorso, face-to-face, or tandem) por manipuli aksajn ŝarĝojn ambaŭdirekte.

Se vi bezonas pli specifajn detalojn (T.e., ŝarĝaj taksoj, toleremoj, or exact dimensions), refer to the manufacturer’s datasheet or product catalog. Popular manufacturers of such bearings include SKF, NSK, Fag, kaj Timken.
