61818/W64 Bearing Product Overview & Core Advantages
The 61818/W64 is a metric single row deep groove ball bearing engineered for reliable performance in demanding applications. This open-type bearing is designed primarily to handle radial loads efficiently. Its construction from high-grade chrome steel ensures durability and consistent operation. A key advantage is its Solid Oil lubrication system, which provides long-term, maintenance-free service by permanently retaining lubricant within the bearing structure, making it ideal for applications where re-lubrication is difficult or undesirable.
61818/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning | Benefit |
|---|---|---|
| 61818 | Standard designation for a single row deep groove ball bearing with a 90mm bore and 115mm OD. | Indicates standard dimensions for easy interchangeability and sourcing. |
| W64 | Specifies the Solid Oil lubrication system. | Ensures permanent lubrication, eliminates leakage, and enables maintenance-free operation. |
| (Open) | No seals or shields are fitted. | Allows for higher limiting speeds and is suitable for clean environments or where external sealing is provided. |
61818/W64 Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and chrome steel construction provide excellent radial load capacity and reliable operation under standard loads.
- Solid Oil Lubrication: This advanced system replaces traditional grease with a porous polymer saturated with oil. It prevents oil leakage, excludes contaminants, and guarantees consistent lubrication throughout the bearing's service life, supporting a wide temperature range from -30°C to 120°C.
- Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class with a standard (CN) radial internal clearance, ensuring consistent performance and smooth operation for general industrial applications.
- High-Speed Capability: The open design and effective Solid Oil lubrication contribute to a high limiting speed of 7,000 rpm.
61818/W64 Bearing Typical Application Areas
This bearing is well-suited for a variety of industrial applications, including:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment
- Agricultural Machinery
- Pumps and Fans
- Any application requiring a reliable, maintenance-free radial ball bearing solution.
