7317 BECBY Bearing Product Overview & Core Advantages
The 7317 BECBY is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. This precision bearing is designed to accommodate significant axial loads in one direction simultaneously with radial loads, making it ideal for high-rigidity and high-speed configurations. Manufactured to a P6 (ABEC-3) tolerance class, it ensures exceptional running accuracy and operational reliability. Its optimized 40° contact angle provides excellent axial load capacity, while the open design facilitates efficient lubrication management for demanding operational conditions.

| Suffix Code | Technical Meaning | Performance Advantage |
|---|---|---|
| BE | Increased internal clearance and optimized internal design | Enhanced performance under thermal expansion and high-speed conditions |
| CB | Specific internal clearance and contact angle configuration | Optimized for combined load applications and precise axial positioning |
| Y | Special cage design and guidance system | Improved high-speed capability and stability |
7317 BECBY Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The single row angular contact design with a 40° contact angle provides exceptional stiffness and can accommodate substantial combined loads. With a radial dynamic load rating of 35,100 lbf and static load rating of 29,700 lbf, this bearing delivers reliable performance in demanding applications.
Precision Engineering: Manufactured to P6 tolerance class (equivalent to ABEC-3), the bearing ensures minimal runout and consistent performance. The brass cage provides excellent guidance and stability at high speeds, contributing to the limiting speed of 4,800 rpm.
Optimized Geometry: Critical dimensions including shoulder diameters (outer ring: 144.95 mm, inner ring large-side: 122.3 mm) are precisely controlled to ensure proper mounting and load distribution. The 76 mm distance from side face to load point enables accurate positioning in the application.
Material Quality: Constructed from chrome steel for both rings and balls, the bearing offers high durability and wear resistance. The brass cage ensures smooth operation across the entire temperature range of -30° to 110°C.
