R166571420 Original Rexroth Linear Bearing Block Specifications
The Rexroth R166571420 linear bearing block is designed with precise technical attributes to meet rigorous industrial demands. Below is a detailed comparison of its key parameters, including metric and imperial conversions for clarity.
| Parameter | Value | Engineering Explanation |
|---|---|---|
| Nominal Size | 30 mm (1.18 in) | Defines the standard size of the runner block, critical for compatibility with guide rails. |
| Width of Runner Block | 90 mm (3.54 in) | Ensures stability and load distribution across the flange width. |
| Length of Runner Block | 75.3 mm (2.96 in) | Short length optimizes use in space-constrained applications. |
| Height of Runner Block | 35.35 mm (1.39 in) | Standard height ensures proper alignment with guide rails. |
| Dynamic Load Capacity C100 | 25,600 N (5,755 lbf) | Maximum load the block can handle dynamically over 100,000 m travel. |
| Dynamic Load Capacity C50 | 32,300 N (7,256 lbf) | Higher load capacity for 50,000 m travel, per DIN ISO 14728-1. |
| Static Load Capacity C0 | 28,900 N (6,497 lbf) | Maximum static load the block can withstand without deformation. |
| Maximum Acceleration amax | 500 m/s² (1,640 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 reliable operation. |
| Friction Coefficient μ | 0.002–0.003 | Low friction ensures energy efficiency and smooth motion. |
| Weight | 0.8 kg (1.76 lb) | Lightweight design reduces system inertia. |
| Permissible Ambient Temperature | -10 °C to +80 °C (14 °F to 176 °F), 100 °C (212 °F) short-term | Ensures reliable operation across a wide temperature range. |
