Its key advantages include robust construction with chrome steel components, a lightweight nylon cage for smooth operation, and integrated seals for contamination protection, making it a versatile and durable solution for various industrial and precision applications.
627-2RSLTN9/C3GMG Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| 627 | Standard bearing series designation with 7mm bore, 22mm OD. | Defines the core bearing dimensions. |
| 2RSL | Contact seals on both sides made of Nitrile Rubber (NBR). | Provides effective sealing against dust and moisture, enhancing bearing life. |
| TN9 | Polyamide (Nylon) cage, glass fiber reinforced, molded type. | Lightweight cage contributes to low friction, quiet running, and is suitable for higher speeds. |
| C3 | Greater than normal radial internal clearance. | Accommodates thermal expansion in applications with high operating temperatures or heavy loads. |
| GMG | Indicates the bearing is supplied with a lithium soap based grease. | Pre-lubricated for immediate use, offering a wide temperature range from -30°C to 120°C. |
627-2RSLTN9/C3GMG Bearing Structural Features & Performance Benefits
This bearing's performance is derived from its specific design features. The single row deep groove raceway is optimized for handling radial loads efficiently. The use of high-grade chrome steel for rings and balls ensures high durability and wear resistance. The TN9 nylon cage minimizes friction and allows for a high limiting speed of 30,000 rpm, making it suitable for high-speed applications. The 2RSL contact seals effectively retain lubricant and exclude contaminants, significantly extending service intervals and promoting reliable, maintenance-free operation. The C3 radial clearance provides operational stability in environments prone to thermal expansion.
