W 61809-2RZ Bearing Product Overview & Core Advantages
The W 61809-2RZ is a metric single row deep groove ball bearing engineered for precision applications requiring reliable performance. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RZ) with pre-applied grease, providing effective protection against contaminants and enabling maintenance-free operation. This bearing is designed to handle primarily radial loads and is characterized by its compact cross-section, making it ideal for applications where space is limited and high reliability is demanded.
W 61809-2RZ Bearing Model Code Explained, Specifications & Naming Convention
The model number W 61809-2RZ can be broken down as follows:
- W: Denotes a bearing with a stainless steel construction.
- 61809: The basic bearing designation, indicating a deep groove ball bearing with a 45 mm bore, 58 mm outside diameter, and 7 mm width.
- 2RZ: This suffix indicates the sealing type. "2" means two seals, one on each side. "RZ" specifies non-contact rubber seals with steel reinforcements, offering effective protection with low friction.
W 61809-2RZ Bearing Structural Features & Performance Benefits
- Full Stainless Steel Construction: Provides superior corrosion resistance, making the bearing suitable for harsh environments and applications requiring washdown.
- Sealed for Life: The 2RZ seals effectively shield the internal components from dust, moisture, and other contaminants. Combined with the pre-applied grease, this creates a maintenance-free solution, reducing lifecycle costs.
- Precision and Low Friction: Manufactured to P0 tolerance class and featuring a low-friction seal design, this bearing ensures smooth operation and is suitable for applications with a limiting speed of 12,000 rpm.
- Robust Load Capacity: With a dynamic load rating of 1111 lbf and a static load rating of 1124 lbf, it is capable of handling significant radial loads for its compact size.
W 61809-2RZ Bearing Typical Application Areas
This bearing is commonly used in:
- Electric Motors and Small Gearboxes
- Medical and Dental Equipment
- Food and Beverage Processing Machinery
- Precision Instruments and Optical Devices
- Conveyor Systems and Material Handling Equipment
