S635 2rs Bearing Product Overview & Core Advantages
The S635 2RS is a metric single row deep groove ball bearing engineered for precision and reliability in demanding applications. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RS), which effectively retains lubricant and excludes contaminants, making it a robust, low-maintenance solution. This bearing is designed to primarily handle radial loads and is characterized by its compact dimensions (5mm bore, 19mm OD, 6mm width), making it ideal for applications where space is limited and operational integrity is critical.
S635 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| S | Stainless Steel Construction | Provides superior corrosion resistance. |
| 635 | Bore Size Code (5mm) | Standardized sizing for easy integration. |
| 2RS | Double Contact Seals (Nitrile Rubber) | Offers excellent protection against contaminants and grease leakage, enabling maintenance-free operation. |
S635 2rs Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and stainless steel cage provide stable operation and reliable performance under radial dynamic loads up to 402 lbf.
- Optimized Sealing: The double-lipped Nitrile rubber seals (2RS) ensure a well-protected internal environment, significantly extending bearing service life in dusty or humid conditions.
- Precision & Speed: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3: 0.002mm to 0.013mm), ensuring smooth running and a high limiting speed of 28,800 rpm.
- Material Integrity: Full stainless steel construction ensures consistent performance across a wide temperature range from -30°C to 110°C and resists corrosion.
S635 2rs Bearing Typical Application Areas
This bearing is ideally suited for:
- Precision Instruments and small medical devices
- Electric Motors and small gearboxes
- Food processing and packaging machinery (benefiting from its stainless steel and sealed design)
- Office automation equipment, such as printers and scanners
- Various low-torque, high-speed drives and spindles
