K19020AR0 Bearing Structural Features & Performance Benefits
High Precision Construction: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore tolerance: -0.025mm to 0, OD tolerance: -0.03mm to 0) ensuring consistent performance in precision applications.
Superior Load Capacity: The 30° contact angle enables exceptional axial load capacity (13,631 lbf static) while maintaining substantial radial load capacity (12,495 lbf static). The single row design with optimized raceway geometry provides efficient load distribution.
Premium Material Selection: Constructed with chrome steel rings and chrome steel balls for durability and wear resistance. The brass cage ensures stable operation and reduced friction at various speeds.
Thin Section Advantage: With only 20mm width and large 190mm bore, this bearing offers maximum space utilization while maintaining structural integrity and high rigidity.
Wide Temperature Range: Operating temperature range from -30°C to 110°C makes it suitable for diverse industrial environments.
