W 625-2RS1 Bearing Product Overview & Core Advantages
The W 625-2RS1 is a metric miniature deep groove ball bearing designed for precision applications requiring compact dimensions and reliable performance. This single row bearing excels at handling primarily radial loads and is sealed on both sides (2RS1) with contact seals for effective contamination protection. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its compact design, with a 5 mm bore and 16 mm outside diameter, makes it ideal for applications where space is limited and high reliability is paramount.
Model Code Breakdown
The model designation "W 625-2RS1" provides key technical specifications:
- W: Indicates a bearing with a wide inner ring.
- 625: Standard bearing designation for a series with a 5 mm bore and 16 mm outside diameter.
- 2RS1: Denotes the sealing type. "2" means two seals, "RS" indicates contact seals made of Nitrile Rubber (NBR), and "1" specifies the seal design. This provides superior protection against dust and moisture ingress.
W 625-2RS1 Bearing Structural Features & Performance Benefits
- Robust Sealed Construction: The double-sided contact seals (2RS1) effectively retain the factory-applied grease and exclude contaminants, ensuring long-term performance and reduced maintenance needs.
- Corrosion Resistance: All components, including rings, balls, and cage, are made of stainless steel, making the bearing suitable for harsh environments and applications requiring washdown.
- Precision and Reliability: Built to P0 tolerance class and standard CN radial internal clearance, this bearing offers consistent performance for a wide range of general-purpose applications.
- Pre-Lubricated for Long Life: The bearing is pre-lubricated with grease, providing reliable operation within its specified temperature range of -30°C to 120°C and contributing to its limiting speed of 28,000 rpm.
W 625-2RS1 Bearing Typical Application Areas
This bearing is commonly used in:
- Small electric motors and gearboxes
- Precision instruments and medical devices
- Office automation equipment (printers, scanners)
- Radio control models and drones
- Food processing and packaging machinery (due to stainless steel construction)
