R18245232X Original Rexroth Linear Bearing Block Specifications
The following table outlines the critical technical parameters of the Rexroth R18245232X linear bearing block, providing a clear comparison of its capabilities and their practical implications.
| Parameter | Value | Engineering Explanation |
|---|---|---|
| Nominal size | 55 mm | Defines the size compatibility with guide rails, ensuring proper fit in linear motion systems. |
| Format | SLH (slimline, long, high) | Compact width, extended length, and increased height for enhanced stability and load capacity. |
| Material | Unalloyed carbon steel | Provides high strength and durability for heavy-duty applications. |
| Preload class | C2 (medium preload) | Balances rigidity and smooth motion, reducing play under load. |
| Accuracy class | H (high) | Ensures precise positioning for applications requiring tight tolerances. |
| Seal | DS (double-lip seal) | Protects against contaminants, extending service life in harsh environments. |
| Width of runner block | 100 mm (3.94 in) | Determines the block’s footprint, critical for system integration. |
| Length of runner block | 209.65 mm (8.25 in) | Extended length enhances stability and load distribution. |
| Height of runner block | 68 mm (2.68 in) | Contributes to the block’s vertical stability and load-bearing capacity. |
| Height with guide rail | 80 mm (3.15 in) | Total height when mounted, critical for clearance calculations. |
| Dynamic load capacity C100 | 174,000 N | Measures the block’s ability to handle dynamic loads over 100,000 m travel (per DIN ISO 14728-1). |
| Dynamic load capacity C50 | 214,000 N | Higher capacity for 50,000 m travel, reflecting enhanced durability. |
| Static load capacity C0 | 374,900 N | Indicates maximum stationary load the block can withstand. |
| Maximum acceleration amax | 150 m/s² | Supports high-speed operations with maintained preload under load. |
| Maximum linear speed vmax | 4 m/s | Defines the top speed for linear motion, ensuring system efficiency. |
| Friction coefficient μ | 0.0004 – 0.001 | Low friction enhances efficiency and reduces wear. |
| Weight | 6.8 kg (14.99 lb) | Moderate weight balances strength and ease of integration. |
| Permissible ambient temperature | -10 °C to +80 °C (14 °F to 176 °F), 100 °C (212 °F) briefly | Wide temperature range supports diverse operating conditions. |
