Technical Advantages
Engineered for demanding industrial automation, the Rexroth linear bearing block R162281422 combines C1 low preload classification with N-grade accuracy (JIS B 1192 compliant), delivering exceptional moment stiffness (350Nm static torsional capacity) while maintaining ultra-low friction coefficient (μ=0.002-0.003). Its 4-way equal load design ensures 22,200N dynamic load capacity (C100) across all directions, making it ideal for precision linear motion systems requiring corrosion resistance and high torque load capacity.
