F687 2rs Bearing Product Overview & Core Advantages
The F687 2rs is a single row deep groove ball bearing featuring integral rubber seals (2RS) on both sides. This metric series bearing is engineered for reliable performance in applications requiring robust radial load capacity and effective contamination protection. Its compact design, with a 7 mm bore and 14 mm outside diameter, makes it an ideal solution for space-constrained assemblies. The bearing is pre-lubricated and sealed for life, offering a maintenance-free operation within its specified temperature range, delivering high reliability for continuous duty cycles.
F687 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| F687 | Basic bearing designation indicating the specific size series (6) and dimensions (87). | Defines the compact bearing size with a 7mm bore and 14mm OD. |
| 2RS | Contact Nitrile Rubber Seals on both sides of the bearing. | Provides excellent protection against contaminants and retains lubricant, enabling maintenance-free operation. |
F687 2rs Bearing Structural Features & Performance Benefits
The performance of the F687 2RS is derived from its optimized construction:
- Deep Groove Raceway & Single Row Design: This fundamental geometry is highly effective at handling radial loads and moderate combined loads, providing smooth and quiet operation.
- Stainless Steel Cage: The cage ensures proper ball spacing and guidance, contributing to stable operation and extended service life.
- Integrated Rubber Seals (2RS): These contact seals are the primary feature, creating an effective barrier against dust, moisture, and other contaminants. This sealing solution preserves the grease integrity, making the bearing lubricated for life and suitable for applications where re-lubrication is impossible.
- Chrome Steel Components: Both the rings and balls are manufactured from high-grade chrome steel, providing excellent wear resistance and durability for a long fatigue life.
F687 2rs Bearing Typical Application Areas
The F687 2RS is widely specified in compact, motorized, and fractional horsepower devices across various industries. Common applications include:
- Small Electric Motors: Used in fans, blowers, and small appliance motors.
- Precision Instruments: Suitable for optical encoders, gauges, and medical devices.
- Office Automation Equipment: Found in printers, scanners, and copiers.
- Radio Control Models: Ideal for servos and small gearboxes.
- Low-Power Drives: Applicable in small conveyor systems and actuators.
