W 608-2RS1/R799 Bearing Product Overview & Core Advantages
The W 608-2RS1/R799 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Constructed entirely from stainless steel, it offers superior corrosion resistance. Its key advantage lies in its sealed design (2RS1) with pre-lubrication (R799), providing long-term, maintenance-free operation by effectively excluding contaminants and retaining lubricant. This bearing is engineered to handle primarily radial loads and is characterized by its compact dimensions, high limiting speed, and reliable operation across a wide temperature range, making it an ideal choice for applications requiring high reliability and durability.
Model Code Breakdown
- W: Bearing series designation.
- 608: Standard bore diameter (8 mm), outer diameter (22 mm), and width (7 mm) dimensions.
- 2RS1: Signifies the bearing is fitted with two rubber contact seals, one on each side. This provides excellent protection against dust, moisture, and other contaminants.
- R799: Indicates the bearing is pre-lubricated with a specific, high-quality grease (R799) suitable for the specified operating temperature range.
W 608-2RS1/R799 Bearing Structural Features & Performance Benefits
Robust Sealed Construction: The 2RS1 rubber contact seals are the cornerstone of this bearing's durability, offering superior contaminant exclusion compared to non-contact shields, thereby extending service life in harsh environments.
Maintenance-Free Operation: The combination of effective seals and factory-applied R799 grease eliminates the need for re-lubrication, reducing maintenance costs and downtime.
High-Speed Capability: The precision single row deep groove raceway and optimized internal geometry contribute to a high limiting speed of 48,000 rpm, enabling efficient performance in high-speed applications.
Corrosion Resistance: Manufactured from stainless steel for both rings and balls, this bearing is highly resistant to corrosion, making it suitable for use in wet, humid, or chemically aggressive environments.
W 608-2RS1/R799 Bearing Typical Application Areas
The W 608-2RS1/R799 is ideally suited for a wide range of applications where reliability, corrosion resistance, and sealed operation are critical. Common uses include:
- Electric Motors and small gearboxes
- Food and Beverage Processing Equipment (due to stainless steel construction and sealing)
- Medical Devices and laboratory equipment
- Agricultural Machinery
- Conveyor systems, rollers, and material handling equipment
- Various industrial machinery requiring compact, sealed ball bearings
