61802/W64 Bearing Product Overview & Core Advantages
The 61802/W64 is a metric miniature deep groove ball bearing designed for compact, high-precision applications requiring reliable performance in limited spaces. As a single row bearing with an open design, it excels in handling primarily radial loads. Its key advantages include a compact cross-section, high rotational accuracy from its ABEC 1 (ISO P0) tolerance class, and long-term, maintenance-free operation enabled by its integrated Soild Oil lubrication. This makes it an ideal choice for applications demanding high reliability and minimal maintenance.
61802/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61802 | Standard series designation for a metric miniature deep groove ball bearing with a 15mm bore, 24mm OD, and 5mm width. |
| W64 | Suffix indicating the bearing is pre-lubricated with Soild Oil, a polymer-based lubricant offering excellent life and contamination resistance. |
61802/W64 Bearing Structural Features & Performance Benefits
- Robust Construction & High Precision: Manufactured entirely from chrome steel for rings, balls, and cage, ensuring consistent hardness, wear resistance, and dimensional stability. The ABEC 1 precision and tight dimensional tolerances contribute to smooth, low-vibration operation.
- Optimized Load Capacity: The deep groove raceway geometry is engineered to efficiently support radial dynamic loads up to 427 lbf and radial static loads up to 247 lbf.
- Maintenance-Free & Contamination Resistant: The integrated Soild Oil lubrication is permanently sealed within the bearing structure, eliminating relubrication needs and providing excellent protection against lubricant washout and dust ingress, even in the open configuration.
- Wide Operating Range: Suitable for a broad temperature range from -30°C to 120°C, making it versatile for various industrial environments.
61802/W64 Bearing Typical Application Areas
This bearing is commonly specified in applications where compact size, reliability, and low maintenance are critical. Key sectors include:
- Small Electric Motors: Used in fans, pumps, and precision drives.
- Office Automation Equipment: Such as printers, scanners, and copiers.
- Medical Devices: Including small handheld instruments and diagnostic equipment.
- Instrumentation and Control Systems: For precise rotational guidance in encoders and sensors.
