Key Features:
The double row configuration significantly increases load capacity and structural rigidity compared to single row bearings, making this bearing exceptionally suitable for applications requiring superior stiffness and combined loading conditions. The 25° contact angle provides an optimal balance between radial and axial load handling capabilities. The dual cover design (2ZR) effectively protects the bearing against contamination and moisture while maintaining slightly increased radial clearance for flexibility in installation and thermal expansion accommodation. The polyamide cage ensures smooth, reliable operation with reduced friction and enhanced durability.
Typical Applications:
- Heavy-duty gearboxes and transmission systems
- Large industrial electric motors
- Machine tool spindles and precision machinery
- Automotive transmission components
- Industrial pumps and compressors
- Turbomachinery and rotating equipment
- Construction and mining equipment
- High-capacity industrial bearings for demanding environments
