RHRE25

chmotion RHRE25 Eccentric Stud Cam Roller
Size 25 Cam Roller with Eccentric Stud for Rexroth Guide Rail Systems R1921 & T-slot R1922

Key Advantages

• Eccentric stud design: Enables precise adjustment (±0.45mm eccentricity) for optimal alignment in guide rail applications.
• High dynamic load capacity: 1280N radial dynamic load (Cy) and 340N axial dynamic load (Cz) for robust performance in demanding environments.
• Rexroth compatibility: Direct interchange with R1900 125 00 for seamless integration into standard R1921 and T-slot R1922 guide rails.
• Compact dimensions: 17mm outside diameter (D2) and 21.4mm overall width (H5) for space-efficient installations.
• Precision options: Available in Normal, P6, or P5 tolerances with customizable internal clearance for single or double row configurations.
