7220 BEP Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The 40° contact angle and optimized raceway geometry enable the bearing to efficiently handle significant combined radial and axial loads in one direction. The single row design with reinforced shoulders provides excellent axial rigidity for precise shaft positioning.
High-Speed Performance: The lightweight nylon cage ensures smooth operation at the limiting speed of 4,000 rpm, reducing centrifugal forces and maintaining stability. The open construction facilitates efficient lubrication management for thermal control.
Precision Engineering: Manufactured to P6 tolerance class with strict dimensional control on bore diameter (100 mm), outside diameter (180 mm), and width (34 mm), ensuring consistent performance in precision applications.
Material Excellence: Constructed from chrome steel for both rings and balls, providing high hardness, wear resistance, and durability across the operating temperature range of -30°C to 110°C.
7220 BEP Bearing Typical Application Areas
- Machine Tool Spindles: High-precision machining centers and grinding spindles
- Industrial Pumps: Centrifugal pumps and compressor systems
- Gearboxes: Precision transmission systems requiring axial positioning
