F698 2rs Bearing Product Overview & Core Advantages
The F698 2RS is a metric single row deep groove ball bearing designed for reliable performance in compact spaces. Featuring integrated rubber seals (2RS) on both sides, this bearing provides excellent protection against contamination while retaining lubrication. Its chrome steel construction and precision manufacturing ensure consistent operation under radial loads with moderate axial capacity. The F698 2RS is particularly valued for applications requiring compact dimensions (8mm bore × 19mm OD × 6mm width) and maintenance-free operation due to its pre-lubricated, sealed design.
Model Code Detailed Breakdown
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| F698 | Basic bearing designation indicating metric dimensions: 8mm bore, 19mm OD, 6mm width | Standardized sizing for easy replacement and integration |
| 2RS | Contact rubber seals on both sides | Superior contamination protection and lubricant retention |
F698 2rs Bearing Structural Features & Performance Benefits
Deep Groove Raceway Design: Optimized for handling radial loads with capability for moderate axial loads in both directions, making it versatile for various mounting configurations.
Double Rubber Seals (2RS): Nitrile rubber seals provide effective barrier against dust, moisture, and other contaminants while maintaining low friction operation. The contact seals offer superior protection compared to non-contact shields.
Precision Components: Manufactured with chrome steel rings and balls combined with a stainless steel cage that ensures stable ball guidance and reliable performance at speeds up to 36,000 rpm.
ABEC1 Precision Class: Provides consistent running accuracy suitable for most industrial applications where high precision is not the primary requirement.
MC3 Radial Clearance: Standard radial internal clearance (0.002-0.013mm) ensures proper operation across typical temperature ranges and fit conditions.
F698 2rs Bearing Typical Application Areas
- Small Electric Motors: Ideal for compact DC motors, fan motors, and miniature power tools
- Office Equipment: Printers, scanners, copiers, and other precision office machinery
- Medical Devices: Small medical instruments and laboratory equipment requiring reliable, maintenance-free operation
- Consumer Electronics: Computer cooling fans, small appliances, and recreational equipment
- Automotive Accessories: Small pumps, actuators, and auxiliary drives where space is limited
- Industrial Automation: Small conveyor systems, positioning devices, and light-duty robotic joints
