R165111320 Original Rexroth Linear Bearing Block Parameters
The table below outlines the key technical specifications of the Rexroth R165111320 linear bearing block, with measurements in both metric and imperial units for global compatibility.
| Parameter | Value | Engineering Explanation |
|---|---|---|
| Nominal Size | 15 mm (0.59 in) | Defines the standard size of the block, critical for rail compatibility. |
| Width of Runner Block (A) | 47 mm (1.85 in) | Width of the block, impacting load distribution and mounting space. |
| Length of Runner Block (B) | 58.2 mm (2.29 in) | Length affects stability and load-bearing capacity. |
| Height of Runner Block (H1) | 19.9 mm (0.78 in) | Height of the block, determining vertical clearance. |
| Height with Guide Rail (H) | 24 mm (0.94 in) | Total height including rail, critical for system integration. |
| Dynamic Load Capacity (C100) | 9860 N (2216 lbf) | Maximum dynamic load for 100,000 m travel, per DIN ISO 14728-1. |
| Dynamic Load Capacity (C50) | 12400 N (2788 lbf) | Dynamic load for 50,000 m travel, offering higher capacity for shorter distances. |
| Static Load Capacity (C0) | 12700 N (2855 lbf) | Maximum static load the block can withstand without deformation. |
| Dynamic Torsional Moment (Mt100) | 95 Nm (70 ft-lb) | Resistance to twisting forces during dynamic operation. |
| Static Torsional Moment (Mt0) | 120 Nm (88.5 ft-lb) | Static resistance to torsional loads, ensuring stability. |
| Maximum Acceleration (amax) | 500 m/s² (1640 ft/s²) | Maximum acceleration for high-speed applications, reduced to 50 m/s² under specific load conditions. |
| Maximum Linear Speed (vmax) | 5 m/s (16.4 ft/s) | Top speed for linear motion, ensuring smooth operation. |
| Friction Coefficient (μ) | 0.002 – 0.003 | Low friction ensures minimal energy loss and heat generation. |
| Weight | 0.2 kg (0.44 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 | Operating temperature range, with consultation required for sub-zero conditions. |
