7316 BECBM Bearing Product Overview & Core Advantages
The 7316 single row angular contact ball bearing is a precision bearing engineered for applications requiring high accuracy and reliability. Its defining feature is a 40° contact angle, which enables it to support combined loads—significant radial loads and substantial axial loads in one direction simultaneously. Manufactured to a P6 (ABEC-3) tolerance class, it guarantees exceptional running accuracy. The open design allows for versatile lubrication options, making it suitable for high-speed operations up to 6,300 rpm. Its robust construction from chrome steel ensures durability and long service life in demanding environments.
7316 BECBM Bearing Model Code Explained, Specifications & Naming Convention
The model number 7316 can be broken down into its core components. Unlike bearings with extensive suffixes, this model's strength lies in its fundamental, high-performance design.
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 7316 | Basic Bearing Number | Indicates a metric, single row angular contact ball bearing with an 80 mm bore, 170 mm OD, and 39 mm width. |
| Open (No Seal) | Seal Type | Allows for high-speed capability and the use of advanced lubrication systems (oil jet, oil mist) for optimal performance. |
| P6 | Tolerance Class | Equivalent to ABEC-3, denoting high precision dimensions and running accuracy. |
7316 BECBM Bearing Structural Features & Performance Benefits
- Optimized Internal Geometry: The 40° contact angle and precisely calculated shoulder diameters (inner ring: 115.2 mm / 97.07 mm) are designed to maximize axial load capacity while maintaining excellent radial load performance.
- High-Speed Brass Cage: The brass cage provides superior strength and guidance at high rotational speeds, contributing directly to the bearing's limiting speed of 6,300 rpm.
- Superior Rigidity and Load Capacity: With a dynamic load rating of 32,175 lbf and a static load rating of 26,550 lbf, this bearing offers high rigidity and is capable of handling demanding combined loads.
- Precision-Grade Materials: Constructed from high-grade chrome steel for both rings and balls, ensuring high fatigue life and operational reliability.
7316 BECBM Bearing Typical Application Areas
The 7316 angular contact ball bearing is ideally suited for high-performance machinery where precision and speed are critical.
- Machine Tool Spindles: Provides high rigidity and accuracy for milling, grinding, and turning centers.
- High-Speed Pumps and Compressors: Handles combined radial and axial loads at high operational speeds.
