R162342320 Original Rexroth Linear Bearing Block Specifications
| Specification | Technical Details | Explanation |
|---|---|---|
| Precision Grades | C3/C5/C7, JIS B grade, DIN H tolerance | Determines the accuracy and quality of linear motion, ensuring the bearing block moves with minimal deviation. |
| Preload Types | Z0 (light), Z1 (medium), Z3 (heavy) | Preload type indicates the amount of pressure applied to the bearing, affecting performance in different load conditions. |
| Rigidity | Moment stiffness, Axial rigidity, Deflection resistance | These metrics assess the bearing block’s resistance to deformation under load, ensuring consistent performance even under stress. |
| Friction Characteristics | Dynamic friction coefficient, Stiction threshold | Friction levels affect the smoothness of motion. Lower friction ensures smoother, more efficient movement. |
| Load Capacity | Static load rating (C0), Dynamic load rating (C), Moment load limits | Load ratings determine how much weight the bearing block can handle before failure, ensuring reliability in heavy-duty applications. |
| Tolerance Parameters | Parallelism tolerance, Height variation, Width deviation | These parameters ensure the bearing block is precisely aligned during installation, reducing errors and enhancing performance. |
Test Environment: Room temperature, 60% humidity
