W 628/6-2RS1 Bearing Product Overview & Core Advantages
The W 628/6-2RS1 is a metric single row deep groove ball bearing designed for reliable performance in compact spaces. Its key advantage lies in its ability to efficiently handle radial loads while offering a sealed design for enhanced protection. Constructed entirely from stainless steel, this bearing provides excellent corrosion resistance, making it suitable for applications requiring high reliability and longevity. The combination of a sealed design and pre-applied grease ensures consistent performance with minimal maintenance.
W 628/6-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
- W 628/6: Basic model number for a metric, single row deep groove ball bearing with a 6 mm bore.
- -2RS1: Designates the sealing type. "2RS1" indicates that the bearing is fitted with contact seals on both sides, providing effective protection against contaminants and retaining lubricant.
W 628/6-2RS1 Bearing Structural Features & Performance Benefits
The single row deep groove raceway geometry is optimized for high-speed operation and smooth rotation under radial loads. The stainless steel construction of the rings, balls, and cage ensures superior corrosion resistance and operational integrity in harsh environments. The contact seals (2RS1) effectively shield the internal components from dust, moisture, and other contaminants, while the factory-applied grease lubrication provides long-term, maintenance-free operation within the specified temperature range of -30° to 120 °C. With a limiting speed of 30,000 rpm and a P0 tolerance class, this bearing offers a robust and precise solution for demanding applications.
W 628/6-2RS1 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of compact and precision equipment, including:
- Small electric motors and gearboxes
- Medical and dental instruments
- Precision spindles and small machinery
- Office automation equipment (e.g., printers, scanners)
- Food processing machinery (benefiting from its stainless steel construction)
