Robust Sealing: ZZ-type dual metal shields prevent contamination from dust, moisture, and debris in harsh environments (e.g., farmland, construction sites)78.
High-Speed Capability: Optimized for RPM-intensive applications with grease lubrication (limiting speed: 2,860 rpm)8.
Durability: GCr15 steel construction ensures wear resistance and longevity under shock/vibration loads17.
Versatile Precision: Supports multiple tolerance classes (P0-P2) for balance between cost and accuracy requirements7.
Agricultural Machinery: Sprocket assemblies in rice transplanters, balers, and hay tedders137.
Industrial Equipment: Printing presses, conveyor systems, and light-duty gearboxes56.
Replacement Use: Interchangeable with legacy models like 203RRAR10 in pillow blocks7.
Thermal Mounting Recommended: For high-interference fits, heat bearing to 80-100°C to avoid force damage during installation56.
