S6918 2rs Bearing Product Overview & Core Advantages
The S6918 2RS is a single row deep groove ball bearing designed for high-performance applications requiring reliable operation under radial loads. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its sealed design (2RS) provides robust protection against contaminants, while the ABEC-1 precision class ensures consistent running accuracy. This bearing is engineered for applications demanding durability, moderate speed capability, and long-term reliability in challenging environments.
S6918 2rs Bearing Model Code Explained, Specifications & Naming Convention
- S6918: Basic designation for a metric, single row deep groove ball bearing with a 90mm bore.
- 2RS: Denotes the bearing is equipped with two rubber contact seals (RS), one on each side. This provides superior protection against moisture and solid contaminants compared to non-contact shields.
S6918 2rs Bearing Structural Features & Performance Benefits
The bearing's performance is defined by its robust construction. The deep groove raceway and stainless steel cage are optimized for handling significant radial dynamic load ratings (6636 lbf). The double rubber contact seals (2RS) effectively retain lubricant and exclude pollutants, significantly extending service life and reducing maintenance needs. The C0 radial internal clearance is a standard group suitable for most common operating conditions. The all-stainless-steel construction ensures reliable performance across a wide temperature range from -86 to 230 °F, making it ideal for applications where corrosion resistance is critical.
S6918 2rs Bearing Typical Application Areas
The S6918 2RS is well-suited for a variety of industrial and specialized equipment, including:
- Food and Beverage Processing Machinery
- Chemical and Pharmaceutical Processing Equipment
- Marine and Submerged Applications
- Medical Devices and Laboratory Equipment
- Agricultural Machinery
