W 623-2RS1 Bearing Product Overview & Core Advantages
The W 623-2RS1 is a metric miniature deep groove ball bearing engineered for precision and reliability in compact spaces. As a single row, sealed bearing, it is specifically designed to handle radial loads efficiently. Its construction from stainless steel throughout (rings, balls, and cage) provides excellent corrosion resistance, making it suitable for applications requiring cleanliness and durability. The combination of a P0 tolerance class and CN radial internal clearance ensures consistent, high-quality performance, while the pre-applied grease lubrication and integrated seals offer a maintenance-free solution for the bearing's operational life.
W 623-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Advantage |
|---|---|---|
| W | Stainless Steel Deep Groove Ball Bearing | Indicates full stainless steel construction for enhanced corrosion resistance. |
| 623 | Bore: 3 mm, OD: 10 mm, Width: 4 mm | Defines the compact bearing dimensions (3x10x4 mm). |
| 2RS1 | Contact Seals on Both Sides | Provides superior protection against contaminants and retains lubricant effectively, contributing to a maintenance-free and long service life. |
W 623-2RS1 Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The 2RS1 contact seals effectively shield the bearing's internals from dust, moisture, and other contaminants. This design preserves the grease lubrication, ensuring smooth operation and significantly extending the bearing's lifespan without requiring re-lubrication.
- High Precision & Consistency: Manufactured to P0 tolerance class and CN radial internal clearance, this bearing guarantees precise running accuracy and low vibration, which is critical for sensitive and high-precision mechanisms.
- Corrosion-Resistant Construction: The use of stainless steel for all key components (rings, balls, and cage) makes the bearing ideal for applications exposed to humid or corrosive environments, such as medical devices, food processing equipment, and laboratory instruments.
- Compact and Lightweight: With dimensions of just 3x10x4 mm and a weight of only 0.0015 kg, this bearing is an optimal solution for applications where space and weight are critical constraints.
W 623-2RS1 Bearing Typical Application Areas
The W 623-2RS1 is ideally suited for a wide range of small, precision-driven equipment, including:
- Small Electric Motors and Gearboxes
- Medical and Dental Hand Tools
- Precision Instruments and Optical Devices
- Office Automation Equipment (e.g., printers, scanners)
- Radio Control Models and Drones
- Food and Beverage Machinery (due to its stainless steel construction)
