Product Description

Customizable High Speed Roller Bearings 22207 Standard Size Bearings For Mining Machinery

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

Model Positioning and Basic Attributes

Type: Spherical roller bearing with 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 35 mm (07×5 calculation) with typical outer diameter ≈ 72 mm and width ≈ 23 mm

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
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

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)
