| Code Segment | Technical Meaning |
|---|---|
| F694 | Basic bearing series designation, indicating a flanged miniature bearing with specific dimensional standards. |
| 2RS | Contact Rubber Seals on both sides. Provides superior protection against dust and moisture ingress, retaining lubricant effectively for extended service life. |
F694 2rs Bearing Structural Features & Performance Benefits
- Robust Construction & High-Speed Capability: Manufactured from Chrome Steel rings and balls with a Stainless Steel cage, this bearing ensures durability and stable operation. The optimized design supports a limiting speed of 48,000 rpm, making it suitable for high-velocity applications.
- Effective Sealing & Lubrication: The Nitrile Rubber seals (2RS) provide excellent exclusion of contaminants while retaining grease. This design contributes to a maintenance-free operation in many environments, enhancing reliability.
- Precision & Load Handling: Built to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), it offers consistent performance and can handle dynamic radial loads up to 183 lbf and static loads of 63 lbf.
- Integrated Flange Design: The flange (12.5mm outer diameter) simplifies mounting and axial location, reducing assembly complexity and cost.
F694 2rs Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in miniature DC motors and stepper motors.
- Office Automation Equipment: Used in printers, scanners, and copiers for paper feed rollers and scanner heads.
- Medical Devices: Suitable for handheld medical tools, dental handpieces, and small pump systems.
- Robotics & RC Models: Applied in joint assemblies, gearboxes, and drive wheels of small-scale automated systems and hobbyist models.
- Instrumentation & Measurement Devices: Supports rotating components in encoders, gauges, and other precision instruments.
