6218-2RS1/W64 Bearing Product Overview & Core Advantages
The 6218-2RS1/W64 is a single row deep groove ball bearing engineered for exceptional reliability in demanding applications. This sealed bearing excels at handling radial loads while also accommodating moderate axial loads in both directions. Its compact design and metric dimensions make it an ideal, space-saving solution. A key advantage is its Solid Oil lubrication system, which ensures consistent performance and significantly extends service intervals, making it a robust choice for applications requiring high operational reliability and minimal maintenance.
6218-2RS1/W64 Bearing Model Code Explained, Specifications & Naming Convention
The model number 6218-2RS1/W64 provides detailed technical specifications:
- 6218: Standard designation for a single row deep groove ball bearing with a 90 mm bore and 160 mm outside diameter.
- 2RS1: Indicates the bearing is fitted with two rubber contact seals (one on each side). These seals provide superior protection against contamination and retain lubricant effectively.
- W64: Denotes that the bearing is pre-lubricated with Solid Oil. This advanced lubrication technology offers excellent resistance to washout, extends relubrication intervals, and is suitable for a wide operating temperature range.
6218-2RS1/W64 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for both rings, balls, and cage, this bearing offers high strength and durability. It features a high radial dynamic load rating of 21,604 lbf and a static load rating of 16,074 lbf, enabling it to withstand significant operational stresses.
- Superior Sealing & Lubrication: The 2RS1 rubber contact seals effectively shield the internal components from contaminants like dust and moisture. Combined with the Solid Oil (W64) filling, the bearing is protected against lubricant leakage and is essentially maintenance-free for its entire service life under normal conditions.
- Precision & Speed Performance: Built to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, it ensures smooth and quiet operation. The bearing is capable of operating at a limiting speed of 4,000 rpm, making it suitable for a wide range of industrial speeds.
6218-2RS1/W64 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Pumps and Compressors
