R18513232X Original Rexroth Linear Bearing Block Parameters
| Parameter | Value | Engineering Explanation |
|---|---|---|
| Nominal Size | 35 mm (1.38 in) | Defines the block’s compatibility with size 35 guide rails, ensuring proper fit and load distribution. |
| Width of Runner Block | 100 mm (3.94 in) | Flanged width provides a stable mounting surface for secure attachment. |
| Length of Runner Block | 118 mm (4.65 in) | Normal length balances compactness with sufficient roller contact for load support. |
| Height of Runner Block | 41 mm (1.61 in) | Standard height ensures compatibility with common linear rail systems. |
| Dynamic Load Capacity C100 | 61,000 N | Maximum load the block can handle during motion over 100,000 m travel, ensuring durability. |
| Static Load Capacity C0 | 119,400 N | Maximum stationary load capacity, critical for heavy-duty applications. |
| Dynamic Torsional Moment Load Capacity Mt100 | 1,210 Nm | Resists twisting forces during dynamic operation, enhancing stability. |
| Static Torsional Moment Load Capacity Mt0 | 2,370 Nm | Ensures rigidity against torsional loads when stationary. |
| Maximum Acceleration amax | 150 m/s² | Supports high-speed operations with preload maintained under load. |
| Maximum Permissible Linear Speed vmax | 4 m/s | Defines the top speed for reliable linear motion performance. |
| Friction Coefficient μ | 0.0004 – 0.001 | Low friction ensures energy efficiency and smooth motion without seal resistance. |
| Weight | 1.87 kg (4.12 lbs) | Lightweight yet robust, reducing system inertia while maintaining strength. |
| Permissible Ambient Temperature | -10°C to +80°C (14°F to 176°F) | Operates reliably in standard industrial environments, with short-term tolerance up to 100°C (212°F). |
