SF695 Bearing Product Overview & Core Advantages
The SF695 is a metric miniature ball bearing designed for precision applications requiring compact dimensions and reliable performance. Constructed entirely from stainless steel, this single row, open bearing offers excellent corrosion resistance. It is engineered to handle primarily radial loads and is characterized by its low weight and suitability for high-speed operation, making it ideal for applications demanding high precision and compact design.
SF695 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF695 | Basic bearing designation indicating the bearing size with a 5mm bore, 13mm OD, and 4mm width. |
| Open | No seals or shields are present. This allows for higher limiting speeds but requires a specific lubrication regime and a clean operating environment. |
| ABEC1 | Specifies the precision class, denoting standard tolerances for runout and dimensions. |
| MC3 | Indicates the radial internal clearance group, which is a "C3" clearance (greater than normal) suitable for applications with thermal expansion or interference fits. |
SF695 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and making the bearing suitable for harsh environments and clean applications.
- High-Speed Capability: The open design and lightweight stainless steel cage contribute to a high limiting speed of 38,700 rpm, enabling use in demanding, high-velocity mechanisms.
- Precision Performance: Manufactured to ABEC1 tolerance class, this bearing ensures consistent running accuracy and smooth operation, which is critical for precision instruments.
- Optimized Internal Geometry: With 8 precision balls of 2mm diameter, the bearing provides a balanced load distribution and low rotational torque.
- Flexible Mounting: The standard MC3 radial clearance allows for stable operation in applications where thermal expansion or press-fits are a factor.
SF695 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of compact and precision devices, including:
- Small Electric Motors (e.g., in drones, RC models, small fans)
- Precision Instruments and optical devices
- Medical Equipment and dental handpieces
- Office Automation Equipment (printers, scanners)
- Textile Machinery spindles
- Various miniature mechanical systems requiring reliable, high-speed rotation
