61808-2RS1/W64F Bearing Product Overview & Core Advantages
The 61808-2RS1/W64F is a metric single row deep groove ball bearing engineered for compact applications requiring high reliability and precision. This sealed bearing excels in handling radial loads and moderate axial loads in one direction, making it an ideal solution for space-constrained designs. Its solid oil lubrication and sealed construction provide long-term, maintenance-free operation, ensuring consistent performance in demanding environments. The bearing is manufactured to ABEC 1 | ISO P0 tolerance standards, offering excellent value for general precision applications.
61808-2RS1/W64F Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| -2RS1 | Double Contact Seals (NBR Rubber) | Provides superior contamination protection and effective grease retention, enabling operation in dusty or humid conditions. |
| /W64F | Solid Oil Lubrication with Fluorine-based Additives | Ensures maintenance-free operation, eliminates lubricant leakage, and provides stable performance across the specified temperature range (-30°C to 120°C). |
61808-2RS1/W64F Bearing Structural Features & Performance Benefits
Optimized Single Row Design: The deep groove raceway and precision-ground chrome steel components provide excellent radial load capacity (1009 lbf dynamic / 843 lbf static) and smooth operation.
Sealed & Lubricated for Life: The combination of double contact seals (2RS1) and Solid Oil (W64F) creates a completely sealed system. This prevents lubricant washout and contaminant ingress, resulting in a maintenance-free bearing with an extended service life.
High-Speed Capability: The precision construction and effective lubrication allow for a limiting speed of 16,000 rpm, making it suitable for a wide range of high-speed applications.
Standardized Precision: Manufactured to ABEC 1 (ISO P0) tolerance class with CN radial internal clearance, ensuring reliable, consistent performance and easy interchangeability.
61808-2RS1/W64F Bearing Typical Application Areas
- Small Electric Motors: Ideal for spindle and rotor support in fractional horsepower motors, fans, and blowers.
- Office Automation Equipment: Used in printers, scanners, and copiers for precise paper handling mechanisms.
- Medical Devices: Suitable for low-noise, maintenance-free operation in small pumps, dental handpieces, and diagnostic equipment.
- Automotive Auxiliary Units: Applied in idler pulleys, tensioners, and small actuators where reliability is critical.
- Precision Instruments & Gearboxes: Provides smooth, low-friction rotation in compact instrumentation and light-duty transmission systems.
