S6702 Bearing Product Overview & Core Advantages
The S6702 is a metric single row deep groove ball bearing engineered for precision radial load applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance and reliable performance. Its compact design, with a 4 mm width and low weight of 3.6 g, makes it ideal for space-constrained assemblies. The bearing operates effectively across a wide temperature range from -86 to 230 °F and adheres to ABEC-1 tolerance standards, ensuring consistent quality and fit.
S6702 Bearing Model Code Explained, Specifications & Naming Convention
The S6702 model code indicates its standard, open design. Below is a breakdown of its key specifications:
- S67: Denotes a specific series of miniature, stainless steel deep groove ball bearings.
- 02: Indicates the bore diameter code. For this series, "02" corresponds to a 15 mm bore diameter.
- No Sealing Suffix: The absence of a sealing suffix (e.g., -2RS) confirms this is an open bearing, requiring external lubrication for optimal performance.
- No Clearance Suffix: The standard radial internal clearance is C0 (Normal).
S6702 Bearing Structural Features & Performance Benefits
- All-Stainless Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and suitability for harsh environments, including washdowns or chemical exposure.
- Deep Groove Raceway: The geometry of the deep groove raceway enables the bearing to handle not only radial loads but also moderate axial loads in both directions.
- High-Speed Capability: With a limiting speed of 9,900 rpm, this bearing is well-suited for high-speed applications such as small precision spindles and high-RPM motors.
- Precision Engineering: Manufactured to ABEC-1 tolerance class, it ensures smooth, quiet operation and reduced vibration, contributing to the overall precision of the application.
- Compliance: The bearing is compliant with ROHS and REACH regulations, making it suitable for use in products with strict environmental and safety standards.
S6702 Bearing Typical Application Areas
The S6702 is commonly specified in applications requiring a compact, corrosion-resistant, and precision bearing:
- Precision Instruments: Optical encoders, medical devices, and laboratory equipment.
- Small Electric Motors: High-speed fans, miniature DC motors, and servo drives.
- Office Automation Equipment: Printers, scanners, and copiers.
- Food and Beverage Machinery: Equipment requiring frequent washdowns due to its stainless steel construction.
- Robotics and Automation: Joints, guides, and small actuators.
