W 61701-2ZS Bearing Product Overview & Core Advantages
The W 61701-2ZS is a 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 ability to handle radial loads efficiently while offering moderate axial load capacity in both directions. The inclusion of shielded seals (2ZS) and pre-applied grease lubrication ensures long-term, maintenance-free operation, making it ideal for applications demanding high reliability and cleanliness.

W 61701-2ZS Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a 4mm width and a weight of only 0.0028 kg, this bearing is engineered for space-constrained applications without compromising performance.
- Corrosion Resistance: The use of stainless steel for rings, balls, and cage ensures reliable operation in humid or corrosive environments and complies with ROHS and REACH standards.
- Sealed & Lubricated for Life: The shielded seals (2Z) effectively protect against contaminants while retaining the grease lubrication, enabling maintenance-free operation across a wide temperature range of -30°C to 120°C.
- Precision & Speed: Manufactured to P0 tolerance class with CN radial internal clearance, it provides consistent performance and can achieve a limiting speed of 38,000 rpm.
W 61701-2ZS Bearing Typical Application Areas
- Precision Instruments: Optical encoders, measuring devices, and small medical instruments.
- Small Electric Motors: Miniature DC motors, stepper motors, and fan motors.
- Office Automation Equipment: Printers, scanners, and copiers.
- Food & Beverage Machinery: Small conveyors and dispensers where corrosion resistance is critical.
