S63801 2rs Bearing Product Overview & Core Advantages
The S63801 2RS is a metric single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity and compact design. Manufactured entirely from stainless steel with integrated seals (2RS), it offers excellent corrosion resistance and protection from contaminant ingress. Its ABEC-1 precision class ensures consistent operation, making it an ideal choice for applications demanding high reliability and long service life in challenging environments.
S63801 2rs Bearing Model Code Explained, Specifications & Naming Convention
The model designation S63801 2RS can be broken down as follows:
- S6: Indicates a bearing manufactured from stainless steel for enhanced corrosion resistance.
- 3801: Denotes the specific bearing size series with a 12mm bore, 21mm outside diameter, and 7mm width.
- 2RS: Signifies that the bearing is equipped with contact seals on both sides. These seals provide superior protection against dust and moisture compared to shielded variants, contributing to the bearing's maintenance-free characteristics when used within specified conditions.
S63801 2rs Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All components, including rings, balls, and cage, are made from stainless steel. This provides outstanding resistance to rust and corrosion, extending bearing life in humid or chemically aggressive environments.
- Effective Sealing Solution: The double-sided contact seals (2RS) effectively retain lubricant and exclude contaminants, making the bearing suitable for applications where low maintenance is a priority.
- Optimized for Radial Loads: The deep groove raceway and single-row design are engineered to handle significant radial dynamic load ratings (388 lbf), ensuring stable performance under primary radial forces.
- Precision Operation: Built to ABEC-1 tolerance class with controlled radial internal clearance (C0), this bearing delivers smooth and quiet running, minimizing vibration and power loss.
S63801 2rs Bearing Typical Application Areas
This bearing is well-suited for a variety of precision equipment and devices, including:
- Food processing and packaging machinery
- Medical and dental equipment
- Small electric motors and gearboxes
- Precision instruments and optical devices
- Agricultural sprayers and marine applications
