W 61804-2RS1/W64 Bearing Product Overview & Core Advantages
The W 61804-2RS1/W64 is a single row deep groove ball bearing designed for exceptional performance in compact, high-precision applications. Constructed entirely from stainless steel and featuring integrated sealing with Solid Oil lubrication, this bearing offers superior corrosion resistance and is effectively maintenance-free. Its design is optimized to support high radial loads while accommodating moderate axial loads in both directions, making it an ideal choice for applications demanding high reliability, long service life, and consistent operation within a wide temperature range.
Model Code Breakdown
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| W | Stainless Steel Bearing | Provides excellent corrosion resistance. |
| 61804 | Basic designation for a single row deep groove ball bearing with a 20mm bore. | Defines the bearing dimensions and type. |
| 2RS1 | Contact seals on both sides. | Offers superior protection against contaminants and retains lubricant effectively. |
| /W64 | Solid Oil lubrication. | Ensures a consistent lubricant supply, eliminates leakage, and enables maintenance-free operation. |
W 61804-2RS1/W64 Bearing Structural Features & Performance Benefits
Robust Stainless Steel Construction: Both rings and balls are made from stainless steel, providing inherent resistance to rust and corrosion, which is critical for harsh environments or washdown applications.
Effective Sealing with 2RS1: The double-sided contact seals effectively shield the bearing interior from moisture, dust, and other contaminants while securely retaining the lubricant, significantly extending bearing service life.
Maintenance-Free Operation with Solid Oil: The W64 suffix indicates the bearing is filled with Solid Oil, a polymer matrix saturated with lubricant. This design prevents oil leakage, is not washout, and provides reliable lubrication throughout the bearing's operational life, reducing total cost of ownership.
Precision and Speed: Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing ensures smooth and quiet running. The optimized design and effective lubrication contribute to a high limiting speed of 13,000 rpm.
W 61804-2RS1/W64 Bearing Typical Application Areas
