623 2rs Bearing Product Overview & Core Advantages
The 623 2RS is a metric single row deep groove ball bearing designed for exceptional reliability in compact applications. This sealed bearing features integral rubber contact seals (2RS) on both sides, providing superior protection against contaminants and retaining lubricant. Engineered from chrome steel with a stainless steel cage, it offers robust performance for radial loads and is pre-lubricated for immediate use. Its compact dimensions (3mm bore, 10mm OD) make it ideal for applications where space is limited but dependable operation is critical.
Model Code Breakdown
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 623 | Basic bearing series designation, indicating a metric deep groove ball bearing with a 3mm bore and 10mm outside diameter. | Standardized dimensions for easy interchangeability and sourcing. |
| 2RS | Contact seals (RS) made of Nitrile Rubber (Buna-N) on both sides (2). | Provides excellent exclusion of contaminants and retention of grease, leading to extended service life and reduced maintenance. |
623 2rs Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High-Quality Steel: The deep groove geometry, combined with chrome steel rings and balls, enables efficient handling of radial dynamic loads up to 121 lbf and provides smooth, low-friction operation.
- Robust Sealing Solution: The Nitrile Rubber contact seals (2RS) create an effective barrier against dust, moisture, and other fine particles. This design is crucial for maintaining performance in contaminated environments.
- Stainless Steel Cage: The cage, manufactured from stainless steel, offers high strength and corrosion resistance, ensuring stable ball guidance and reliable performance at the limiting speed of 50,000 rpm.
- Standard Internal Clearance (MC3): With a radial internal clearance of 0.002mm to 0.013mm, this bearing is suitable for a wide range of standard applications, accommodating typical fits and operating temperatures from -30°C to 110°C.
