R18224222X Original Rexroth Linear Bearing Block Specifications
The R18224222X is designed to meet stringent performance standards. Below is a detailed comparison of its technical parameters:
| Parameter | Value | Engineering Explanation |
|---|---|---|
| Nominal Size | 45 mm (1.77 inches) | Defines the block’s size for compatibility with guide rails. |
| Format | SNS (slimline, normal, standard height) | Compact width, standard length, and height for versatile applications. |
| Material | Carbon Steel | Ensures durability and resistance to wear in heavy-duty environments. |
| Preload Class | C2 (Medium Preload) | Balances rigidity and smooth motion under moderate loads. |
| Accuracy Class | P (Precision) | Guarantees high accuracy for precise linear motion control. |
| Seal | DS (Double-lip Seal) | Protects against dust and contaminants, extending service life. |
| Width of Runner Block | 86 mm (3.39 inches) | Provides stable contact with the guide rail. |
| Length of Runner Block | 147 mm (5.79 inches) | Ensures sufficient roller contact for load distribution. |
| Height of Runner Block | 51 mm (2.01 inches) | Compact height for space-efficient installations. |
| Height with Guide Rail | 60 mm (2.36 inches) | Total height when mounted on a standard guide rail. |
| Dynamic Load Capacity C100 | 106,600 N | Supports high dynamic loads over 100,000 m travel (per DIN ISO 14728-1). |
| Dynamic Load Capacity C50 | 131,000 N | Higher capacity for 50,000 m travel, ideal for shorter strokes. |
| Static Load Capacity C0 | 209,400 N | Handles substantial static loads without deformation. |
| Maximum Acceleration (amax) | 150 m/s² | Supports high-speed operations with maintained preload. |
| Maximum Linear Speed (vmax) | 4 m/s | Ensures reliable performance in fast-moving systems. |
| Friction Coefficient (μ) | 0.0004 – 0.001 | Low friction enhances efficiency and reduces wear. |
| Weight | 2.76 kg (6.08 lbs) | Lightweight for its size, easing installation. |
| Permissible Ambient Temperature | -10 °C to +80 °C (14 °F to 176 °F), 100 °C (212 °F) short-term | Operates reliably in varied environmental conditions. |
