R162452310 Original Rexroth Linear Bearing Block Specifications
The R162452310 linear bearing block is designed to meet stringent performance standards. Below is a detailed comparison of its technical parameters, presented in a structured format for clarity.
| Parameter | Value | Engineering Explanation |
|---|---|---|
| Nominal Size | 55 mm | Defines the size class, ensuring compatibility with corresponding guide rails. |
| Format | SLH – Slimline, Long, High | Indicates a compact width, extended length, and tall height for high rigidity in tight spaces. |
| Material | Carbon Steel | Provides strength and durability for heavy-duty applications. |
| Preload Class | C2 – Medium Preload | Ensures balanced stiffness and smooth motion under moderate loads. |
| Accuracy Class | H – Highly Accurate | Guarantees precise positioning for high-precision tasks. |
| Seal | SS – Standard Seal | Protects against contaminants, extending service life. |
| Width of Runner Block | 100 mm (3.94 in) | Determines the block’s transverse footprint, ideal for compact designs. |
| Length of Runner Block | 199 mm (7.83 in) | Extended length enhances stability and load distribution. |
| Height of Runner Block | 67 mm (2.64 in) | Contributes to the block’s high rigidity and load capacity. |
| Dynamic Load Capacity C100 | 139,000 N | Measures the block’s ability to handle dynamic loads over 100,000 m travel. |
| Static Load Capacity C0 | 245,000 N | Indicates the maximum static load the block can withstand without deformation. |
| Maximum Acceleration amax | 250 m/s² (820 ft/s²) | Defines the maximum acceleration for dynamic applications (50 m/s² under high combined loads). |
| Maximum Permissible Linear Speed vmax | 5 m/s (16.4 ft/s) | Ensures safe operation at high speeds. |
| Permissible Ambient Temperature | -10 °C to +80 °C (14 °F to 176 °F), 100 °C (212 °F) for short periods | Specifies the operational temperature range, with consultation advised for extreme conditions. |
| Friction Coefficient μ | 0.002 to 0.003 | Low friction ensures energy efficiency and smooth motion. |
| Weight | 6 kg (13.23 lb) | Reflects the block’s robust construction for heavy-duty use. |
