W 61708 Bearing Product Overview & Core Advantages
The W 61708 is a metric single row deep groove ball bearing engineered for high-precision radial load applications. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its compact design, with a 6 mm width, makes it ideal for space-constrained assemblies requiring reliable performance and a P0 tolerance class for general precision. The open seal type allows for easy re-lubrication if required, providing flexibility in various operational conditions.
Model Code Breakdown
The model number W 61708 can be interpreted based on standard bearing nomenclature:
- W: Manufacturer's prefix or series identifier.
- 6: Series code, often indicating a deep groove design.
- 17: Bore diameter code. For metric bearings, this typically corresponds to a 40 mm bore.
- 08: Dimension series code, relating to the outer diameter and width.
Key specifications derived from the model and data include: Open construction, Stainless Steel material, and standard CN radial internal clearance.
W 61708 Bearing Structural Features & Performance Benefits
The bearing's performance is defined by its robust construction and material selection:
- All-Stainless-Steel Construction: Provides superior corrosion resistance, making it suitable for harsh environments and applications requiring washdown.
- Single Row Deep Groove Design: Optimized for handling radial loads efficiently. The deep raceways support smooth, high-speed operation.
- High-Speed Capability: With a limiting speed of 16,000 rpm, it is well-suited for high-speed applications.
- Precision & Reliability: Manufactured to P0 tolerance class and standard CN radial internal clearance, ensuring consistent performance and interchangeability.
- Lightweight & Compact: Weighing only 0.021 kg, it minimizes rotational inertia and is perfect for lightweight designs.
