W 61701 Bearing Product Overview & Core Advantages
The W 61701 is a metric single row deep groove ball bearing engineered for high-performance applications requiring precision and reliability. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its primary function is to support radial loads efficiently. With a compact design featuring a 4 mm width and an open construction, this bearing is ideal for space-constrained assemblies where high limiting speeds are necessary. Its P0 tolerance class and standard CN radial internal clearance ensure consistent performance for general precision applications.
Model Code Breakdown
The model number W 61701 can be interpreted based on common industry nomenclature for miniature and instrument bearings:
- W: Often denotes a manufacturer series or a specific product line.
- 6: Typically indicates a single row deep groove ball bearing type.
- 17: Specifies the bore diameter code. For metric bearings, this often corresponds to a 17 mm bore, but in this case, it designates a 12 mm bore, which is common in miniature bearing series where numbering does not directly correlate to dimensions.
- 01: Frequently relates to a specific dimensional series or variant within the size group.
Key Specification Highlights:
- Seal type: Open - Allows for custom lubrication schemes but requires a clean operating environment.
- Lubrication: None - The bearing is supplied without grease, providing flexibility for the application of specialized lubricants.
- Tolerance class: P0 (Normal) - Standard grade for general applications.
W 61701 Bearing Structural Features & Performance Benefits
The performance of the W 61701 is derived from its robust construction and material selection:
- Full Stainless Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and making the bearing suitable for harsh environments, including those requiring washdown or exposure to certain chemicals.
- High-Speed Capability: The open design and precision-ground components contribute to a high limiting speed of 48,000 rpm, which is critical for applications like small spindles and high-speed rotors.
- Radial Load Capacity: Engineered to handle significant radial dynamic load (118 lbf) and radial static load (60 lbf) for its compact size, ensuring durability and long service life.
- Precision & Stability: Manufactured to P0 tolerance with standard CN clearance, this bearing offers reliable and predictable running accuracy, minimizing vibration and noise.
W 61701 Bearing Typical Application Areas
The compact size, high-speed performance, and corrosion resistance of the W 61701 make it suitable for a wide range of precision equipment and devices, including:
- Precision Instruments and Optical Encoders
- Small Electric Motors and Miniature Gearboxes
- Medical Devices and Dental Handpieces
- Office Automation Equipment (e.g., Printers, Scanners)
- Robotics and Small Actuators
- Radio Control Models and Drones
