61905/W64 Bearing Product Overview & Core Advantages
The 61905/W64 bearing is a metric single row deep groove ball bearing designed for exceptional reliability in radial load applications. Its compact design, featuring a 9 mm width, provides a space-saving solution without compromising performance. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing ensures consistent operation and is pre-lubricated with Soild Oil for long-term, maintenance-free service. Its robust construction from chrome steel makes it a durable choice for a wide range of industrial machinery.
61905/W64 Bearing Model Code Explained, Specifications & Naming Convention
The model number 61905/W64 can be broken down as follows to understand its technical specifications:
- 61905: Indicates the bearing series and size. The "6" denotes a single row deep groove ball bearing. The "1905" specifies a 25 mm bore and a 42 mm outside diameter.
- W64: This suffix signifies that the bearing is lubricated with Soild Oil, a solid polymer-based lubricant that is permanently retained within the bearing, offering excellent resistance to wash-out and enabling long-term, maintenance-free operation.
61905/W64 Bearing Structural Features & Performance Benefits
- High Precision & Reliability: Built to ABEC 1 (ISO P0) tolerance class with a standard CN radial internal clearance, this bearing delivers smooth and precise rotation, minimizing vibration and noise.
- Robust Load Capacity: With a dynamic load rating of 1578 lbf and a static load rating of 967 lbf, it is engineered to handle significant radial loads in demanding applications.
- Maintenance-Free Operation: The integration of Soild Oil lubrication eliminates the need for re-lubrication, reduces contamination risk, and ensures consistent performance across its operating temperature range of -30°C to 120°C.
- Optimized for Speed: The open design and effective lubrication contribute to a high limiting speed of 22,000 rpm, making it suitable for high-speed applications.
61905/W64 Bearing Typical Application Areas
This versatile bearing is ideally suited for applications requiring high reliability and minimal maintenance, including:
- Small Electric Motors and Gearboxes
- Office Automation Equipment (Printers, Scanners)
- Medical Devices and Instrumentation
- Cooling Fans and Blowers
- Conveyor System Idler Rolls
