7084 BGM Bearing Product Overview & Core Advantages
The 7084 metric angular contact ball bearing represents a premium precision bearing solution engineered for demanding applications. Designed as a single row bearing with a significant 40° contact angle, it is optimized to handle high axial loads in one direction while simultaneously supporting substantial radial loads. Manufactured to a P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy and rotational stability. Its robust construction from chrome steel and brass cage ensures high reliability and long service life in high-performance machinery.
7084 BGM Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Interpretation |
|---|---|
| 7084 | Basic bearing designation indicating the bearing size with a 420 mm bore and 620 mm outside diameter. |
| Open (Seal Type) | No integral seals or shields, designed for applications where external sealing is provided or where maximum limiting speed is critical. |
| P6 (Tolerance Class) | Denotes a precision bearing with dimensional and running accuracy superior to standard (P0) grades, equivalent to ABEC-3. |
| 40° (Contact Angle) | Specifies a steep contact angle, which is the key design feature enabling its high axial load capacity. |
7084 BGM Bearing Structural Features & Performance Benefits
- High Axial Rigidity and Load Capacity: The 40° contact angle and optimized internal geometry are specifically engineered to support very high one-direction axial loads and combined loads, providing exceptional stiffness and stability.
- Precision Performance: Manufactured to P6 tolerance, this bearing ensures minimal runout and vibration, which is critical for the accuracy of high-speed spindles and precision machinery.
- Optimized for High-Speed Operation: The brass cage provides excellent strength and guidance at the limiting speed of 1000 rpm, while the open design reduces friction and heat generation.
- Robust Material Construction: Components made from chrome steel offer high hardness, wear resistance, and durability, ensuring a long operational lifespan under heavy loads.
- Clear Internal Geometry: Defined shoulder diameters on both the inner and outer rings ensure precise axial location and secure mounting.
7084 BGM Bearing Typical Application Areas
This bearing is ideally suited for heavy-duty industrial applications requiring high precision and axial stiffness, including:
- Machine Tool Spindles
- Large Industrial Pumps and Compressors
- Gearboxes and Power Transmission Systems
- Precision Turntables and Indexing Tables
- Mining and Construction Equipment
