R162339420 Original Rexroth Linear Bearing Block Features
The R162339420 Linear Bearing Block is designed for applications demanding high precision and reliability. Here are the key technical features:
| Parameter | Specification | Explanation | Industry Standard Comparison |
|---|---|---|---|
| Preload Class | C0 – No Preload | Indicates a preload-free design, ensuring minimal clearance in the linear motion system. | ISO 14728-1, JIS B 1192 |
| Accuracy Class | N – Normal | Standard precision suitable for most linear motion systems, offering a balance of performance and cost. | DIN H tolerance |
| Dynamic Load Capacity (C100) | 66,700 N (14,980 lbf) | Indicates the maximum load the bearing can handle during dynamic movement without failure. | DIN ISO 14728-1 |
| Static Load Capacity (C0) | 116,000 N (26,106 lbf) | Represents the maximum static load the bearing can bear without permanent deformation. | ISO 14728 |
| Maximum Linear Speed | 5 m/s (16.4 ft/s) | The maximum allowable linear speed for this bearing block under normal operational conditions. | Standard linear motion systems |
| Friction Coefficient (μ) | 0.002 to 0.003 | Low friction allows for smoother motion and reduced wear on the linear bearing system. | DIN 6485 |
| Temperature Range | -10°C to +80°C (14°F to 176°F) | Permissible ambient temperature range for the linear bearing block, ensuring operational stability across various environments. | ISO 14728 |
