F7-13M Bearing Product Overview & Core Advantages
The F7-13M is a metric thrust ball bearing engineered for applications requiring precise axial load handling in compact spaces. This open-type bearing delivers reliable performance in thrust load conditions while maintaining minimal cross-section dimensions. Manufactured with chrome steel rings and balls combined with a durable brass cage, it offers excellent durability and stable operation. Its compact design (7mm bore, 13mm OD, 4.5mm width) makes it ideal for applications where space constraints and axial load capacity are critical factors.
F7-13M Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| F7-13M | Basic designation indicating thrust ball bearing with 7mm bore and 13mm outside diameter in metric system |
| Open | No seals or shields, allowing for direct lubrication access and optimal heat dissipation |
| Grooved Raceway | Precision-ground raceways designed for optimal ball guidance and load distribution |
F7-13M Bearing Structural Features & Performance Benefits
High-Precision Construction: The bearing features chrome steel components with tight dimensional tolerances (bore/OD: -0.008mm to 0) ensuring precise fit and reliable performance in precision applications.
Axial Load Capacity: Specifically designed for thrust load applications, it delivers 320 lbf dynamic and 282 lbf static axial load ratings, providing robust performance in demanding conditions.
Optimized Cage Design: The brass cage ensures proper ball spacing and guidance, contributing to smooth operation and extended service life at speeds up to 4,000 rpm.
Compact & Lightweight: With a minimal cross-section (4.5mm width) and lightweight construction (2.6g), it enables space-saving designs without compromising load capacity.
F7-13M Bearing Typical Application Areas
- Precision instruments and measuring devices requiring accurate axial positioning
- Small electric motors and miniature drives where space is limited
- Office automation equipment including printers, scanners, and copiers
