SF698 2rs Bearing Product Overview & Core Advantages
The SF698 2RS is a single row deep groove ball bearing designed for exceptional performance in compact spaces. Engineered with stainless steel rings and balls, it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RS), which provides robust protection against contaminants while retaining lubricant, making it a reliable, low-maintenance solution for applications requiring durability and consistent operation within its specified temperature range.
SF698 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF698 | The basic bearing designation, defining the core bearing dimensions (8mm bore, 19mm OD, 6mm width). |
| 2RS | Indicates the bearing is fitted with two contact seals (one on each side) made of Nitrile Rubber (NBR). This provides superior sealing compared to non-contact shields, effectively keeping contaminants out and lubricant in. |
SF698 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing for Enhanced Lifespan: The dual 2RS contact seals are the cornerstone of this bearing's reliability. They protect the stainless steel components and lubricant from dust, moisture, and other pollutants, significantly extending service life and enabling use in demanding environments.
- High Corrosion Resistance: Constructed entirely from stainless steel (rings, balls, and cage), this bearing is ideal for applications exposed to moisture, chemicals, or washdowns, preventing rust and premature failure.
- Optimized for Radial Loads: The deep groove raceway and complement of 7 precision balls are engineered to efficiently handle the specified radial dynamic load rating of 385 lbf, providing smooth and stable operation.
- Precision and Consistency: Manufactured to ABEC1 tolerance class, this bearing ensures consistent running accuracy and low vibration, suitable for a wide range of general precision applications.
SF698 2rs Bearing Typical Application Areas
- Food and Beverage Processing Equipment
- Medical and Laboratory Devices
- Small Electric Motors and Gearboxes
- Office Automation Equipment (Printers, Scanners)
- Conveyor Systems in Clean or Corrosive Environments
- Agricultural Machinery Components
