628/8-2RS1/W64 Bearing Product Overview & Core Advantages
The 628/8-2RS1/W64 is a metric single row deep groove ball bearing designed for exceptional reliability in compact applications. This sealed bearing features a solid oil lubrication system, providing long-term, maintenance-free operation. Its construction enables it to handle significant radial loads efficiently, making it an ideal choice for applications demanding high precision and consistent performance within a standard tolerance class. The bearing is engineered for durability and stable operation across a wide temperature range.
628/8-2RS1/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 628/8 | Basic bearing series with an 8 mm bore diameter. |
| 2RS1 | The bearing is fitted with two rubber contact seals (one on each side), providing effective protection against contamination. |
| W64 | Indicates the bearing is pre-lubricated with Solid Oil, a polymer matrix saturated with lubricant, ensuring a consistent and long-lasting lubricating film. |
628/8-2RS1/W64 Bearing Structural Features & Performance Benefits
- Robust Sealing & Lubrication: The combination of 2RS1 rubber seals and W64 Solid Oil creates a highly effective, sealed-for-life system. This design prevents lubricant leakage and blocks the ingress of contaminants, resulting in extended service life and maintenance-free operation.
- Radial Load Capacity: The single row deep groove raceway geometry is optimized to support high radial dynamic and static loads relative to its compact size, ensuring reliable performance under demanding conditions.
- Stable Operation & Precision: Manufactured to ABEC 1 | ISO P0 tolerance standards with a CN radial internal clearance, this bearing offers smooth and quiet running, which is critical for precision applications.
- Wide Temperature Suitability: The specified materials and Solid Oil lubrication allow for a functional temperature range from -30°C to 120°C, accommodating various operational environments.
