627-2RSL/C3LHT23 Bearing Product Overview & Core Advantages
The 627-2RSL/C3 is a sealed single row deep groove ball bearing designed for reliable performance in demanding applications. Its compact 7x22x7 mm metric dimensions make it an ideal choice for space-constrained assemblies. A key feature is its C3 radial internal clearance, which accommodates thermal expansion and interference fits, ensuring stable operation under varying thermal conditions. The inclusion of contact rubber seals (2RSL) on both sides provides superior protection against contaminants while retaining lubrication, enhancing service life and enabling use in diverse environments.
Model Code Breakdown
- 627: Basic bearing series, indicating a deep groove ball bearing with a 7 mm bore.
- -2RSL: Designates two integral contact rubber seals (one on each side) for effective sealing against dust and moisture.
- /C3: Indicates a greater than normal radial internal clearance, suitable for applications with shaft expansion or where interference fits are used.
627-2RSL/C3LHT23 Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured from chrome steel for rings, balls, and cage, this bearing offers high strength and durability, contributing to its radial dynamic load rating of 629 lbf and static load rating of 248 lbf.
Effective Sealing: The 2RSL contact seals provide excellent defense against contamination, making the bearing suitable for environments where dirt, dust, or moisture is present. This design helps maintain performance and extends operational life.
Optimized Internal Clearance: The C3 clearance group allows for thermal expansion differences between the shaft and housing, preventing premature failure due to excessive preload, which is critical in applications with operational temperature variations.
Precision & Speed: Built to ABEC 1 | ISO P0 tolerance class, it ensures consistent and reliable performance. The bearing supports a limiting speed of 30,000 rpm, making it suitable for various high-speed applications.
627-2RSL/C3LHT23 Bearing Typical Application Areas
This bearing is widely used in:
- Small Electric Motors (e.g., in power tools, household appliances)
- Precision Instruments and measuring devices
- Office Automation Equipment such as printers and scanners
- Light-duty Gearboxes and transmission systems
- Pumps and Fans requiring reliable, sealed bearing solutions
