627-2RSLTN9/C3LHT23 Bearing Product Overview & Core Advantages
The 627-2RSLTN9/C3 is a single row deep groove ball bearing designed for exceptional reliability in compact applications. This sealed bearing excels in handling significant radial loads while offering moderate axial load capacity in both directions. Its compact design (7mm bore, 22mm OD) makes it ideal for space-constrained, high-speed applications up to 30,000 rpm, requiring minimal maintenance due to its integral seals and pre-defined internal clearance.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 627 | Basic bearing series, indicating a metric deep groove design with specific dimensions (7x22x7mm) |
| 2RSL | Double Contact Seals on both sides, providing superior protection against contamination |
| TN9 | Nylon Cage (Polyamide), enabling smooth operation and reduced friction at high speeds |
| C3 | Greater Radial Internal Clearance than normal, suitable for applications with thermal expansion or where interference fits are used |
627-2RSLTN9/C3LHT23 Bearing Structural Features & Performance Benefits
Optimized Sealing & Protection: The 2RSL double-contact seals effectively retain lubrication and exclude contaminants like dust and moisture, significantly extending service life in demanding environments. This makes the bearing suitable for maintenance-free operation throughout its service life.
High-Speed Capability: The lightweight TN9 nylon cage ensures excellent dimensional stability and low friction, contributing to the bearing's high limiting speed of 30,000 rpm. This is critical for applications requiring rapid rotation with minimal vibration.
Robust Load Handling: Manufactured from chrome steel for both rings and balls, this bearing delivers a dynamic load rating of 629 lbf and a static load rating of 248 lbf. The deep groove raceway geometry is optimized to support substantial radial loads and moderate axial loads from both directions.
Thermal & Fit Adaptability: The C3 radial internal clearance provides operational stability in applications prone to thermal expansion or where press fits are employed, preventing premature failure due to excessive preload.
