W 61700-2ZS Bearing Product Overview & Core Advantages
The W 61700-2ZS is a miniature metric single row deep groove ball bearing engineered for precision applications requiring compact design and reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its shielded (2ZS) design, which provides effective protection against contaminant ingress while being pre-lubricated for maintenance-free operation. This bearing is ideal for applications demanding high rotational accuracy, moderate speeds, and long service life in challenging environments.
Model Code Breakdown
| Model Segment | Technical Meaning |
|---|---|
| W 61700 | Series designation for a miniature, deep groove ball bearing with a 10mm bore. |
| 2Z | Indicates non-contact shields on both sides. This provides excellent protection against dust and other particles without significantly increasing friction, contributing to the bearing's high limiting speed. |
| S | Denotes that the bearing rings and balls are made from stainless steel, offering superior corrosion resistance. |
W 61700-2ZS Bearing Structural Features & Performance Benefits
- Compact and Lightweight Design: With dimensions of 10mm x 15mm x 3mm and a weight of only 0.0013 kg, this bearing is perfect for space-constrained and weight-sensitive applications.
- Corrosion Resistance: The use of stainless steel for all critical components ensures reliable performance in humid or corrosive environments, expanding its operating temperature range from -30°C to 120°C.
- Maintenance-Free Operation: The combination of non-contact shields and factory-applied lubrication makes the bearing sealed for life, eliminating the need for re-lubrication.
- Precision Performance: Manufactured to ABEC 1 / ISO P0 tolerance class with standard radial internal clearance (CN), it provides consistent running accuracy and smooth operation.
W 61700-2ZS Bearing Typical Application Areas
This miniature deep groove ball bearing is widely used in:
- Precision Instruments: Optical encoders, measuring devices, and small gauges.
- Small Electric Motors: Stepper motors, miniature DC motors, and fan motors.
- Office Automation Equipment: Printers, scanners, and copiers.
- Medical Devices: Small pumps, dental handpieces, and laboratory equipment.
- Radio Control Models and Robotics: Servos, small gearboxes, and joint assemblies.
