R165131320 Original Rexroth Linear Bearing Block Specifications
The Rexroth R165131320 linear bearing block is designed to meet stringent engineering requirements. Below is a detailed comparison of its technical 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 handling. |
| Width of runner block | 100 mm (3.94 in) | Provides a wide flange for stable mounting and load distribution. |
| Length of runner block | 110.5 mm (4.35 in) | Determines the block’s footprint, balancing compactness with structural integrity. |
| Height of runner block | 40.4 mm (1.59 in) | Ensures proper alignment with guide rails for smooth motion. |
| Height with guide rail | 48 mm (1.89 in) | Total height when mounted, critical for system design clearance. |
| Dynamic load capacity C100 | 51800 N (11645 lbf) | Maximum load the block can handle dynamically over 100,000 m travel, per DIN ISO 14728-1. |
| Static load capacity C0 | 80900 N (18188 lbf) | Maximum static load the block can withstand without deformation. |
| Dynamic torsional moment load capacity Mt100 | 1110 Nm (818 ft-lb) | Measures the block’s ability to resist twisting forces during dynamic operation. |
| Static torsional moment load capacity Mt0 | 1740 Nm (1283 ft-lb) | Indicates resistance to twisting forces when stationary. |
| Maximum acceleration amax | 500 m/s² (1640 ft/s²) | Maximum acceleration the block can endure, critical for high-speed applications. |
| Maximum permissible linear speed vmax | 5 m/s (16.4 ft/s) | Top speed for safe and efficient linear motion. |
| Friction coefficient μ | 0.002–0.003 | Low friction ensures energy-efficient motion and reduced wear. |
| Permissible ambient temperature | -10 °C to +80 °C (14 °F to 176 °F); 100 °C (212 °F) for short periods | Operating temperature range, ensuring reliability in varied conditions. |
| Weight | 1.7 kg (3.75 lb) | Lightweight yet robust, minimizing system inertia. |
