22207 High Speed Spherical Roller Bearing Self Aligning For Mining Machinery

22207 High-Speed Spherical Roller Bearing (CA+W33 Dual-Optimized Design)

I. Model Positioning and Basic Attributes

• Type: Spherical roller bearing (double-row roller structure, capable of withstanding heavy radial loads + bidirectional axial loads, and accommodating shaft misalignment during installation).
• Basic Dimensions: For model "22207", the bore diameter is calculated as 07×5 = 35 mm (outer diameter and width require manual reference; typical values: outer diameter ≈ 72 mm, width ≈ 23 mm).

II. Suffix Code Interpretation (Core Design)

III. Applications & Advantages

• Typical Scenarios: Mining machinery (crushers), gearboxes, conveyor systems, fans, and other demanding applications requiring high load capacity, self-aligning capability, and lubrication efficiency.
• Core Competitiveness:
  ✔ Self-aligning capability of spherical roller bearings (compensates for shaft misalignment, reducing installation errors).
  ✔ High-speed adaptability of brass cages (higher speed limits vs. steel cages).
  ✔ Long service life guaranteed by W33 lubrication design (continuous lubrication suppresses wear, lowering maintenance frequency).
