627-2RSL/LHT23 Bearing Product Overview & Core Advantages
The 627-2RSL is a metric single row deep groove ball bearing designed for reliable performance in compact spaces. Its key advantage lies in its sealed construction (2RSL), which provides robust protection against contamination. This bearing is engineered to handle primarily radial loads efficiently and is manufactured to ABEC 1 (ISO P0) tolerance standards, ensuring consistent quality and performance. Its compact dimensions (7mm bore, 22mm OD, 7mm width) and sealed, pre-lubricated design make it an ideal, maintenance-free solution for a wide range of applications requiring dependable operation.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 627 | Basic bearing series, indicating a metric, single row deep groove design with a 7mm bore. |
| 2RSL | Contact rubber seals on both sides. The "SL" designation often indicates a low-friction, nitrile rubber seal that provides excellent protection while minimizing torque. |
| /LHT23 | Specifies the grease used for lubrication. LHT23 is a high-quality, synthetic grease suitable for a wide temperature range (-30°C to +120°C). |
627-2RSL/LHT23 Bearing Structural Features & Performance Benefits
- Robust Sealing: The 2RSL contact seals effectively shield the bearing's internals from dust, moisture, and other contaminants, significantly extending service life and enabling use in harsh environments.
- Optimized Lubrication: Pre-lubricated with LHT23 grease, this bearing is ready for immediate use and offers long-term, maintenance-free operation across its specified temperature range.
- Precision & Reliability: Manufactured to ABEC 1 (ISO P0) standards with a CN radial internal clearance, it delivers consistent running accuracy and smooth operation.
- High-Quality Materials: Constructed entirely from chrome steel (rings, balls, and cage), providing high strength, durability, and resistance to wear.
- Compact & Lightweight: With a 7mm width and a weight of only 12.7 grams, it is an excellent choice for applications where space and weight are critical constraints.
627-2RSL/LHT23 Bearing Typical Application Areas
- Small Electric Motors (e.g., cooling fans, power tools)
- Office Machinery (printers, scanners, copiers)
- Medical Devices and Equipment
- Precision Instruments and Gauges
- Conveyor Systems (for small rollers and idlers)
- Food Processing Equipment (where seals prevent contamination)
