627-2RSH/C3 Bearing Product Overview & Core Advantages
The 627-2RSH/C3 is a sealed single row deep groove ball bearing engineered for high reliability in demanding applications. This metric bearing excels at handling primarily radial loads and offers robust performance due to its sealed construction and optimized internal geometry. Its compact design, featuring a 7 mm bore, 22 mm outside diameter, and 7 mm width, makes it an ideal choice for applications where space is at a premium without compromising on load capacity or operational longevity.
627-2RSH/C3 Bearing Model Code Explained, Specifications & Naming Convention
- 627: Basic bearing designation, indicating a single row deep groove ball bearing with a 7 mm bore.
- 2RSH: Signifies that the bearing is equipped with two contact seals (RSH type) on both sides. These seals provide superior protection against contamination and are designed for effective grease retention.
- C3: Indicates a greater radial internal clearance than the standard C0 group. This is beneficial for applications involving thermal expansion, such as those with high operational temperatures or where fits create a reduction in internal clearance.
627-2RSH/C3 Bearing Structural Features & Performance Benefits
The performance of the 627-2RSH/C3 is a direct result of its precision construction. Manufactured from chrome steel for both rings and balls, it ensures high durability and resistance to wear. The contact seals (2RSH) are a critical feature, offering excellent protection against dust, moisture, and other contaminants, thereby significantly extending the bearing's service life and enabling its use in harsh environments. The C3 radial internal clearance provides operational stability in applications prone to thermal expansion. With a limiting speed of 30,000 rpm and a dynamic load rating of 629 lbf, this bearing delivers a robust combination of high-speed capability and reliable load-bearing performance.
627-2RSH/C3 Bearing Typical Application Areas
- Small Electric Motors (e.g., for power tools, household appliances)
- Precision Instruments and medical devices
- Office Automation Equipment such as printers and scanners
- Computer Cooling Fans and spindle drives
- Various light-duty industrial machinery requiring a reliable, sealed bearing solution.
