W 61705 Bearing Product Overview & Core Advantages
The W 61705 is a metric single row deep groove ball bearing engineered for precision radial load applications. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its compact design, with a minimal cross-section, is ideal for applications where space is limited and high reliability is required. The bearing features a P0 tolerance class and standard CN radial internal clearance, ensuring consistent performance and interchangeability.
W 61705 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation |
|---|---|
| W | Designates a stainless steel bearing series. |
| 61 | Indicates the bearing series with a very thin cross-section. |
| 7 | Bore diameter code (specific to the series). |
| 05 | Bore diameter code representing a 25 mm bore. |
| Open (from spec) | No seals or shields, allowing for higher limiting speeds and easy re-lubrication if required. |
W 61705 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: Provides superior corrosion resistance, making it suitable for harsh environments, including those requiring wash-down or exposure to certain chemicals.
- High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 26,000 rpm, ideal for demanding rotational applications.
- Precision Radial Load Support: As a single row deep groove ball bearing, it is primarily designed to carry significant radial loads efficiently.
- Compact and Lightweight: With a width of only 4 mm and a weight of just 0.0063 kg, it is perfect for compact assemblies and reducing overall system weight.
- Standard Tolerance and Clearance: The P0 tolerance class and CN radial internal clearance ensure reliable, predictable performance for a wide range of general-purpose applications.
