R165111420 Original Rexroth Linear Bearing Block Specifications
| Parameter | Value | Explanation |
|---|---|---|
| Nominal Size | 15 mm (0.59 in) | Defines the size of the block, ensuring compatibility with corresponding guide rails. |
| Format | FNS (Flange, Normal, Standard Height) | Indicates flange width, normal length, and standard height for versatile mounting. |
| Material | Carbon Steel | Provides durability and strength for heavy-duty applications. |
| Preload Class | C1 (Low Preload) | Ensures smooth motion with minimal internal forces, ideal for precision tasks. |
| Accuracy Class | N (Normal) | Standard accuracy suitable for most industrial applications. |
| Dynamic Load Capacity C100 | 9860 N (2215 lbf) | Maximum load the block can handle over 100,000 m of travel. |
| Static Load Capacity C0 | 12700 N (2855 lbf) | Maximum static load the block can withstand without deformation. |
| Maximum Acceleration (amax) | 500 m/s² (1640 ft/s²) | Indicates the block’s ability to handle rapid motion changes. |
| Maximum Linear Speed (vmax) | 5 m/s (16.4 ft/s) | Defines the top speed for safe and reliable operation. |
| Permissible Ambient Temperature | -10 °C to +80 °C (14 °F to 176 °F), 100 °C (212 °F) for short periods | Range of temperatures for reliable performance; consult for negative temperatures. |
| Friction Coefficient (μ) | 0.002–0.003 | Low friction ensures energy efficiency and smooth operation. |
| Weight | 0.2 kg (0.44 lbs) | Lightweight design reduces system load while maintaining strength. |
| Width of Runner Block | 47 mm (1.85 in) | Width dimension for mounting and system integration. |
