R163211420 Original Rexroth Linear Bearing Block Parameters

Parameter Value Engineering Explanation
Nominal size 15 mm (0.59 in) Defines the size category for compatibility with guide rails, ensuring proper fit in compact systems.
Width of runner block 34 mm (1.34 in) Slimline width supports space-constrained applications while maintaining stability.
Length of runner block 58.2 mm (2.29 in) Standard length provides a balance between compactness and load-bearing capacity.
Height of runner block 19.9 mm (0.78 in) Standard height ensures compatibility with typical rail systems for consistent performance.
Dynamic load capacity C100 9860 N (2216 lbf) Maximum load the block can handle over 100,000 m travel, critical for heavy-duty applications.
Dynamic load capacity C50 12400 N (2788 lbf) Load capacity for 50,000 m travel, offering higher capacity for shorter travel distances.
Maximum dynamic load Fmax 3000 N (674 lbf) Peak dynamic load the block can withstand during operation, ensuring durability.
Maximum permissible linear speed vmax 5 m/s (16.4 ft/s) Defines the top speed for linear motion, suitable for high-speed automation.
Maximum acceleration rate amax 500 m/s² (1640 ft/s²) Maximum acceleration the block can handle, critical for rapid motion changes.
Maximum permissible torsional moment Mt max 29 Nm (21.39 ft-lb) Resistance to twisting forces, ensuring stability in dynamic applications.
Maximum permissible longitudinal load moment ML max 16 Nm (11.80 ft-lb) Resistance to longitudinal forces, supporting robust performance under load.
Friction coefficient μ 0.002 … 0.003 Low friction ensures smooth motion and energy efficiency in linear systems.
Permissible ambient temperature -10 °C to +80 °C (14 °F to 176 °F), 100 °C (212 °F) for short periods Wide temperature range supports diverse industrial environments.
Weight 0.1 kg (0.22 lbs) Lightweight design reduces system mass, ideal for dynamic applications.
