R18242232X Original Rexroth Linear Bearing Block Parameters
| Parameter | Value | Explanation |
|---|---|---|
| Nominal Size | 25 mm | Indicates the standard size for compatibility with size 25 profiled rail systems. |
| Width of Runner Block | 48 mm (1.89 in) | Defines the width of the block, ensuring proper fit on the guide rail. |
| Length of Runner Block | 115 mm (4.53 in) | Specifies the total length, impacting load distribution and stability. |
| Height of Runner Block | 34 mm (1.34 in) | Height without guide rail, critical for system integration. |
| Height with Guide Rail | 40 mm (1.57 in) | Total height including rail, ensuring compatibility with machinery. |
| Dynamic Load Capacity C100 | 33,300 N (7,480 lbf) | Maximum load the block can handle dynamically over 100,000 m travel (per DIN ISO 14728-1). |
| Dynamic Load Capacity C50 | 41,000 N (9,217 lbf) | Dynamic load capacity for 50,000 m travel, often used for comparison (multiply C100 by 1.23). |
| Static Load Capacity C0 | 76,400 N (17,175 lbf) | Maximum static load the block can withstand without deformation. |
| Dynamic Torsional Moment Load Capacity Mt100 | 432 Nm (318.6 ft-lb) | Torsional moment capacity for dynamic loads over 100,000 m. |
| Static Torsional Moment Load Capacity Mt0 | 990 Nm (729.9 ft-lb) | Maximum static torsional moment the block can endure. |

| Static Longitudinal Moment Load Capacity ML0 | 970 Nm (715.4 ft-lb) | Maximum static longitudinal moment capacity. |
| Maximum Acceleration amax | 150 m/s² (492 ft/s²) | Maximum acceleration under preload, critical for high-speed applications. |
| Maximum Permissible Linear Speed vmax | 4 m/s (13.12 ft/s) | Fastest speed the block can operate without compromising performance. |
| Friction Coefficient μ | 0.0004 … 0.001 | Low friction ensures energy efficiency and smooth motion (excludes seal friction). |
| Permissible Ambient Temperature | -10 °C … +80 °C (14 °F … 176 °F) | Operating temperature range, with brief peaks up to 100 °C (212 °F) permitted. |
| Weight | 0.8 kg (1.76 lb) | Lightweight design reduces overall system weight. |
| Pitch T Guide Rail | 30 mm (1.18 in) | Distance between rail mounting holes, affecting installation spacing. |
| Seal Type | DS (Double-lip seal) | Protects against contaminants, extending service life in harsh conditions. |
