W 61700 Bearing Product Overview & Core Advantages
The W 61700 is a metric miniature deep groove ball bearing engineered for precision applications requiring compact design and reliable performance. Constructed entirely from stainless steel, this single row, open bearing is optimized for radial loads and offers excellent corrosion resistance. Its small bore diameter of 10 mm and slim width of 3 mm make it ideal for space-constrained assemblies. Operating within a temperature range of -30° to 120 °C and compliant with ROHS and REACH standards, it is a versatile component for demanding environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| W | Manufacturer prefix for a specific series of stainless steel miniature bearings. |
| 61700 | Standard series designation indicating the bearing dimensions (10x15x3 mm). |
| Open (No Seal Suffix) | No contact seals, allowing for higher limiting speeds. Requires a clean operating environment or external sealing. |
| P0 Tolerance Class | Standard tolerance class for normal precision applications. |
| CN Radial Clearance | Standard radial internal clearance for most general applications. |
W 61700 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The rings, balls, and stainless steel cage provide superior corrosion resistance, making the bearing suitable for harsh or washdown environments.
- High-Speed Capability: The open design and precision-ground components minimize friction, supporting a limiting speed of 56,000 rpm for a miniature bearing.
- Radial Load Capacity: The deep groove raceway and single-row design are optimized to handle the specified radial dynamic load rating of 110 lbf efficiently.
- Precision Dimensions: Tight tolerances on the bore diameter, outside diameter, and width ensure precise fit and reliable performance in high-accuracy mechanisms.
- Application Flexibility: With lubrication: none from the factory, it can be customized with a specific grease or oil suited to the application's speed, temperature, and life requirements.
W 61700 Bearing Typical Application Areas
- Precision Instruments: Optical encoders, measuring devices, and small laboratory equipment.
- Small Electric Motors: Spindle support in miniature DC motors and stepper motors.
- Office Automation: Paper feed rollers in printers, scanners, and copiers.
- Medical Devices: Low-noise, corrosion-resistant bearings for handheld surgical tools and diagnostic equipment.
- Robotics and RC Models: Joints and drive systems in small-scale automation and hobbyist models.
