W 61906-2RS1 Bearing Product Overview & Core Advantages
The W 61906-2RS1 is a single row deep groove ball bearing designed for high-performance applications requiring reliability and precision. As a metric sealed bearing, it excels in handling radial loads efficiently while offering protection against contamination. Constructed entirely from stainless steel, it provides excellent corrosion resistance. Its compact design, with a 9 mm width, makes it ideal for space-constrained assemblies. The bearing is pre-lubricated with grease, enabling immediate installation and maintenance-free operation across its specified temperature range, ensuring long service life and consistent performance.
W 61906-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W | Designates a stainless steel bearing series. |
| 61906 | The basic bearing designation: "6" for deep groove type, "19" for the dimension series (specifically, a thin section), and "06" for a 30 mm bore diameter. |
| 2RS1 | Indicates the bearing is fitted with two rubber contact seals (RS) on both sides. The "1" suffix often specifies a particular seal design, providing effective protection against contaminants and retaining lubricant. |
W 61906-2RS1 Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All components, including rings, balls, and cage, are made from stainless steel, offering superior corrosion resistance and suitability for harsh environments or washdown applications.
- Effective Sealing with 2RS1: The double rubber contact seals effectively shield the internal components from dust, moisture, and other contaminants while securely retaining the lubricant, contributing to a longer operational life and reduced maintenance.
- Optimized Load Capacity: The deep groove raceway and single-row design are engineered to handle significant radial dynamic and static loads (1403 lbf and 1124 lbf respectively), ensuring reliable performance under demanding conditions.
- Pre-lubricated for Immediate Use: Filled with grease, the bearing is ready for installation and offers smooth, quiet operation from the start, supporting a limiting speed of 8,500 rpm.
- Standard Tolerances and Clearance: Manufactured to P0 tolerance class and CN radial internal clearance, it provides consistent and predictable performance for a wide range of general-purpose applications.
