1209-TVH Bearing Product Overview & Core Advantages
The 1209-TVH is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. This precision bearing features an open design with optimized internal geometry, enabling it to accommodate significant radial loads while simultaneously handling bidirectional axial loads. Its compact dimensions (45mm bore, 85mm OD, 19mm width) make it ideal for space-constrained applications where high load capacity and operational stability are essential. The nylon cage and proper lubrication ensure smooth operation across the specified temperature range.

1209-TVH Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row configuration provides superior radial and moment load capacity compared to single row bearings, ensuring stable operation under heavy combined loads.
Optimized Load Distribution: Precision-engineered raceways and ball complement enable efficient distribution of radial and bidirectional axial loads, extending service life.
Enhanced Speed Performance: The nylon cage reduces friction and enables higher limiting speeds (11,000 rpm) while maintaining operational stability.
Precision Manufacturing: Manufactured with tight dimensional tolerances and CN clearance for consistent performance in precision applications.
Material Excellence: Chrome steel rings and balls provide excellent wear resistance and durability under demanding operating conditions.
