51315 Bearing Structural Features & Performance Benefits
High Load Capacity Design: The 51315 features optimized raceway geometry and high-quality 52100 Chrome Steel components, enabling it to handle axial dynamic loads up to 36,675 lbf and axial static loads up to 87,750 lbf. This makes it suitable for heavy-duty thrust applications.
Precision Engineering: With tight dimensional tolerances (bore diameter: -0.015mm to 0, outside diameter: -0.025mm to 0) and stainless steel cage construction, the bearing ensures smooth operation and minimal vibration at limiting speeds up to 2,400 rpm.
Thermal Stability: The bearing operates effectively within a temperature range of -30°C to 110°C, maintaining performance across various environmental conditions. The open design allows for efficient heat dissipation and custom lubrication solutions.
Material Excellence: Utilizing 52100 Chrome Steel for both rings and balls provides excellent wear resistance and fatigue life, while the stainless steel cage offers corrosion resistance and dimensional stability.
