51224 Bearing Structural Features & Performance Benefits
High Load Capacity Design: The bearing's construction enables it to handle significant axial thrust loads with excellent reliability. The 52100 Chrome Steel rings and balls provide superior strength and wear resistance.
Precision Engineering: Tight dimensional tolerances on bore diameter (-0.02mm to 0) and outside diameter (-0.025mm to 0) ensure precise fit and alignment in application assemblies.
High-Speed Capability: The stainless steel cage maintains ball alignment and stability at limiting speeds of 2,200 rpm, reducing friction and heat generation.
Temperature Resilience: Operating temperature range of -30°C to 110°C ensures reliable performance across various environmental conditions.
