608-2RSH/C3 Bearing Product Overview & Core Advantages
The 608-2RSH/C3 is a sealed single row deep groove ball bearing designed for reliable performance in demanding applications. This metric bearing excels in handling radial loads and, to a lesser extent, axial loads in both directions. Its compact design, featuring a 8 mm bore, 22 mm outside diameter, and 7 mm width, makes it ideal for applications with space constraints. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers consistent precision and high operational reliability.
Model Code In-Depth Explanation
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 608 | Standard deep groove ball bearing series with 8mm bore | Defines the basic bearing dimensions and type. |
| 2RSH | Contact seals on both sides, made of NBR rubber | Provides superior protection against contaminants and retains lubricant effectively. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion, making it suitable for applications with high rotational speeds or temperature fluctuations. |
608-2RSH/C3 Bearing Structural Features & Performance Benefits
Optimized Sealing: The 2RSH contact seals are a key structural feature, offering excellent exclusion of contaminants and superior grease retention compared to non-contact shields. This contributes to a longer service life and reduced maintenance needs.
Radial Internal Clearance (C3): The C3 clearance is a critical performance feature. It prevents bearing seizure by allowing for thermal expansion of the rings and rolling elements under high-speed operation or elevated temperatures, ensuring stable performance.
High-Quality Construction: All core components, including rings, balls, and cage, are manufactured from Chrome Steel, providing high strength, durability, and resistance to wear.
High-Speed Capability: With a limiting speed of 34,000 rpm, this bearing is engineered for high-velocity applications. The combination of precision manufacturing, a robust steel cage, and optimized internal geometry enables smooth operation at high RPMs.
608-2RSH/C3 Bearing Typical Application Areas
The 608-2RSH/C3 is a versatile component found in a wide range of precision machinery and equipment, including:
- Electric Motors: Small motors, fan motors, and servo motors.
- Power Tools: Drills, grinders, and other handheld tools requiring high-speed operation.
- Office Automation Equipment: Printers, scanners, and copiers.
- Medical Devices: Small pumps, dental handpieces, and laboratory equipment.
- Automotive Components: Auxiliary units, alternators, and cooling fans.
