W 617/6 R Bearing Product Overview & Core Advantages
The W 617/6 R is a single row deep groove ball bearing designed for compact applications requiring high precision and reliability. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to efficiently handle radial loads, making it an ideal solution for space-constrained assemblies where dependable performance is critical. The open design facilitates easy lubrication integration and contributes to its lightweight profile.
Model Code Breakdown
- W 617/6: Indicates the bearing series and size designation (6 mm bore).
- R: Signifies the presence of a flange on the outer ring, which simplifies mounting and positioning within a housing.
- Open Seal Type: The bearing is supplied without seals or shields, allowing for higher limiting speeds and custom lubrication options.
- P0 Tolerance Class: Denotes standard dimensional and geometrical accuracy, suitable for a wide range of general applications.
- CN Radial Clearance: Specifies the standard (normal) internal clearance group.
W 617/6 R Bearing Structural Features & Performance Benefits
The bearing's performance is derived from its robust construction. The single row deep groove raceway is optimized for smooth operation under radial dynamic loads (rated at 64 lbf). The integral stainless steel flange provides secure axial location, enhancing mounting rigidity and simplifying assembly. The use of stainless steel for all components, including the cage, ensures consistent performance across the specified temperature range of -30°C to 120°C and resists corrosion. The open design, combined with a standard CN clearance, contributes to its limiting speed of 75,000 rpm, making it suitable for high-speed operation when appropriately lubricated.
W 617/6 R Bearing Typical Application Areas
This miniature flanged bearing is commonly specified in applications requiring compactness and precision, such as:
- Small electric motors and miniature gearboxes
- Precision instruments and optical devices
- Office automation equipment (e.g., printers, scanners)
- Medical devices and laboratory equipment
- Radio-controlled models and drones
