7305 BECBY Bearing Product Overview & Core Advantages
The 7305 BECBY is a single row angular contact ball bearing engineered for applications requiring high precision and reliable performance under combined loads. This precision bearing features a 40° contact angle, optimized to support significant axial loads in one direction while simultaneously handling radial loads. Manufactured to P6 (ABEC-3) tolerance class, it ensures exceptional running accuracy and dimensional stability. Its compact design, with a 25 mm bore and 62 mm outside diameter, makes it ideal for space-constrained, high-performance assemblies demanding high rigidity and operational reliability.
7305 BECBY Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7305 | Basic bearing designation indicating a metric series angular contact ball bearing with 25 mm bore diameter and medium cross-section. |
| BE | Designates 40° contact angle and optimized internal geometry for high axial load capacity. |
| CB | Indicates normal internal clearance and standard internal design. |
| Y | Signifies the bearing is pre-lubricated with high-performance grease for immediate operation. |
7305 BECBY Bearing Structural Features & Performance Benefits
The 7305 BECBY incorporates several critical design elements that deliver superior performance:
- High Rigidity & Load Capacity: The single row design with a 40° contact angle provides excellent resistance to combined (radial and axial) loads. The optimized raceway geometry and high-grade chrome steel construction ensure stable operation under demanding conditions.
- Precision & Speed: Manufactured to P6 tolerance class, this bearing guarantees minimal runout and vibration. The brass cage ensures reliable guidance of the balls, contributing to smooth operation and a limiting speed of 15,000 rpm.
- Ready-to-Use & Durable: The bearing comes pre-lubricated, eliminating the need for initial greasing and enabling immediate installation. The open seal type allows for efficient re-lubrication in service, extending operational life within a temperature range of -30°C to 110°C.
7305 BECBY Bearing Typical Application Areas
The 7305 BECBY angular contact ball bearing is ideally suited for high-performance machinery and systems, including:
- Machine Tool Spindles
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Agricultural Machinery
- Material Handling Equipment
