SF695 2rs Bearing Product Overview & Core Advantages
The SF695 2RS is a single row deep groove ball bearing designed for compact applications requiring reliable performance. This metric bearing features integral rubber seals (2RS) on both sides for effective contamination exclusion. Manufactured entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its primary advantages include a compact flanged design for simplified mounting and axial location, suitability for radial loads, and robust construction for demanding environments. The pre-lubricated and sealed design ensures long-term, maintenance-free operation in a wide temperature range.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| SF695 | Basic bearing designation indicating the bearing size (5mm bore, 13mm OD, 4mm width) and flanged outer ring. |
| 2RS | Signifies contact-type Nitrile Rubber (NBR) Seals on both sides of the bearing. This provides superior protection against dust and moisture ingress compared to non-contact shields. |
SF695 2rs Bearing Structural Features & Performance Benefits
- Flanged Outer Ring: The flange (15mm OD) facilitates precise axial location and simplifies bearing housing design and installation, reducing assembly time and cost.
- Deep Groove Raceway & Single Row Design: This fundamental ball bearing geometry is optimized to handle primarily radial loads efficiently, though it can accommodate moderate axial loads in both directions.
- Full Complement Stainless Steel Construction: The use of stainless steel for all core components ensures high corrosion resistance, making it ideal for applications exposed to moisture, chemicals, or washdowns. The one-piece stainless steel cage provides reliable guidance for the balls.
- Sealed & Pre-lubricated: The double-lipped contact seals (2RS) effectively retain lubricant and exclude contaminants, significantly extending bearing service life and enabling maintenance-free operation. The bearing is supplied with a standard grease suitable for its specified temperature range.
- Precision & Clearance: Built to ABEC1 tolerance class with an MC3 radial internal clearance group, it offers a balance of good running accuracy and operational reliability for a wide range of industrial applications.
SF695 2rs Bearing Typical Application Areas
This versatile, compact, and sealed bearing is commonly specified in:
- Small Electric Motors: Used in miniature DC motors, stepper motors, and fans.
- Precision Instruments & Medical Devices: Ideal for small gearboxes, encoders, pumps, and surgical hand tools.
- Office Automation Equipment: Found in printers, scanners, and copiers.
- Food & Beverage Machinery: Suitable for conveyors and dispensers where corrosion resistance and cleanability are important.
- Robotics & Automation: Used in small joints, guides, and actuators.
