Product Overview and Core Advantages
The 7319 BEGAP is a single row angular contact ball bearing designed for high-precision applications requiring superior performance under combined loads. This precision bearing features a 40° contact angle, enabling it to efficiently support substantial radial loads and unidirectional axial loads simultaneously. Manufactured to P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy and rotational stability. The bearing comes pre-lubricated and is constructed with chrome steel rings and balls combined with a nylon cage, making it ideal for applications demanding high reliability and high-speed operation up to 4,300 rpm.

|---|---|
| 7319 | Basic bearing designation indicating bearing dimensions (95mm bore, 200mm OD, 45mm width) |
| BE | Designates 40° contact angle and optimized internal geometry |
| GA | Indicates pre-lubricated condition for immediate operation |
| P | Specifies P6 tolerance class (equivalent to ABEC-3) for precision applications |
Structural Features and Performance Benefits
Optimized Internal Geometry: The 40° contact angle provides an ideal balance between radial and axial load capacity, making it suitable for combined loading conditions.
High-Speed Capability: The nylon cage reduces friction and enables smooth operation at limiting speeds of 4,300 rpm, while the precision manufacturing ensures minimal vibration.
Superior Load Capacity: With dynamic load rating of 40,500 lbf and static load rating of 36,675 lbf, this bearing delivers reliable performance under demanding conditions.
Precision Engineering: Manufactured to P6 tolerance class with tight dimensional control (bore tolerance: -0.015mm to 0), ensuring consistent performance and easy installation.
Ready-to-Use Design: The pre-lubricated construction eliminates the need for initial lubrication, reducing installation time and ensuring proper lubrication from startup.
