S636 2rs Bearing Product Overview & Core Advantages
The S636 2RS is a sealed single row deep groove ball bearing engineered for precision applications requiring reliable performance in compact spaces. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its primary advantage lies in its ability to handle radial loads efficiently while the integrated Nitrile rubber seals (2RS) on both sides protect against contamination and retain lubrication, making it suitable for applications demanding low maintenance and long service life in various environmental conditions.
S636 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| S636 | Basic bearing designation indicating a metric, single row deep groove ball bearing with a 6mm bore, 22mm OD, and 7mm width. | Defines the core bearing dimensions and type. |
| 2RS | Denotes contact seals made of Nitrile Rubber (NBR) on both sides of the bearing. | Provides effective protection against dust, dirt, and moisture ingress, and helps retain lubricant for extended service intervals. |
S636 2rs Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All critical components—inner ring, outer ring, balls, and cage—are manufactured from stainless steel, providing superior corrosion resistance and durability, ideal for harsh or washdown environments.
- Optimized Radial Load Capacity: The deep groove raceway and complement of 7 precision balls enable high radial dynamic load rating (574 lbf) for its compact size, ensuring reliable performance under significant stress.
- Effective Sealing Solution: The 2RS contact seals effectively shield the internal bearing components from contaminants, significantly extending bearing life and reducing the need for maintenance in dirty or humid conditions.
- Precision & Smooth Operation: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3), this bearing offers consistent and smooth running characteristics suitable for a wide range of industrial applications.
S636 2rs Bearing Typical Application Areas
The S636 2RS is ideally suited for applications where compact size, corrosion resistance, and sealed operation are critical. Common uses include:
- Small Electric Motors and Gear Motors
- Medical and Dental Equipment
- Food Processing and Packaging Machinery
- Precision Instruments and Optical Devices
- Office Automation Equipment (e.g., printers, scanners)
