7419 GAM Bearing Product Overview & Core Advantages
The 7419 is a single row angular contact ball bearing engineered for applications demanding high precision and robust performance. This metric series bearing is designed to accommodate combined loads, efficiently supporting significant radial loads and unidirectional axial loads simultaneously. Its optimized 40° contact angle provides excellent axial load capacity and high rigidity, making it a superior choice for high-speed, high-precision machinery. Manufactured with Chrome Steel rings and balls, and featuring a durable Brass cage, the 7419 ensures reliable operation and long service life in demanding industrial environments.

7419 GAM Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row angular contact design, combined with a 40° contact angle and a robust brass cage, provides exceptional rigidity. This enables the bearing to handle significant combined loads (radial and axial) with high precision.
- Optimized for High-Speed Operation: The open design and precision P6 tolerance class minimize friction and heat generation, supporting a high limiting speed of 3,400 rpm. The brass cage ensures stability and integrity at these elevated speeds.
- Precision Engineering: Manufactured to ABEC-3 (P6) precision standards, this bearing offers tight dimensional control for applications requiring high running accuracy and low vibration.
- Superior Material Construction: The use of Chrome Steel for rings and balls provides high hardness, wear resistance, and a long operational lifespan under heavy loads.
7419 GAM Bearing Typical Application Areas
The 7419 angular contact ball bearing is ideally suited for high-performance machinery where precision, speed, and load capacity are critical. Common applications include:
- Machine Tool Spindles
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Industrial Motors
