R205B42320 Original Rexroth Linear Bearing Block Specifications
| Parameter | Value | Explanation |
|---|---|---|
| Nominal Size | 25 | Refers to the standardized size of the clamping element, ensuring compatibility with corresponding rail systems. |
| Spring Energy Holding Force (Standard Air Port) | 650 N | Force exerted by the spring mechanism to hold the rail without external air pressure, tested with ISO-VG 68 lubrication. |
| Spring Energy Holding Force (Air-Plus Port) | 1050 N | Enhanced holding force when additional air is supplied at 6.0 bar, ideal for heavy-duty applications. |
| Release Pressure | 5.5–8 bar | Pressure range required to decompress the clamp, allowing free movement of the rail system. |
| Air Consumption (Standard Air Port) | 0.015 normal liters | Volume of air used per cycle, indicating efficiency in pneumatic operations. |
| Air Consumption (Air-Plus Port) | 0.082 normal liters | Higher air consumption for increased holding force, suitable for demanding tasks. |
| Height of Runner Block | 32.5 mm (1.28 inches) | Vertical dimension of the clamping unit, critical for fitting within system constraints. |
| Width of Runner Block | 61.4 mm (2.42 inches) | Horizontal dimension, ensuring stability and compatibility with rail systems. |
| Length of Runner Block | 41 mm (1.61 inches) | Length of the clamping unit, affecting the contact area with the guide rail. |
| Permissible Ambient Temperature | 0°C to +60°C (32°F to 140°F) | Operating temperature range, ensuring reliability in various industrial environments. |
| Max. Pneumatic Operating Pressure | 8 bar | Maximum pressure the unit can handle, ensuring safe and efficient operation. |
| Size A (Profiled Rail Systems) | 61.4 mm (2.42 inches) | Overall width of the rail system interface, critical for alignment and stability. |
| Size H (Profiled Rail Systems) | 36 mm (1.42 inches) | Height of the rail system, ensuring proper fit with the clamping element. |
