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)

Suffix	Technical Meaning & Value
CA	Brass cage: - Material properties: High strength and low density, enabling higher rotational speeds (outperforming steel cages). - Corrosion resistance: Resistant to mineral oils and alkaline lubricants, suitable for harsh operating conditions. - Temperature adaptability: Brass cages typically ensure stable operation in medium-to-high-temperature environments (industry commonality).
W33	Outer ring oil grooves + 3 lubrication holes: - Lubrication enhancement: Facilitates external lubrication systems (e.g., oil pumps) for continuous grease/oil lubrication, significantly reducing roller wear. - Operating condition adaptability: Optimized for heavy loads, high speeds, or harsh scenarios (e.g., dust, moisture), improving bearing service life and stability.

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).
