R165111220 Original Rexroth Linear Bearing Block Specifications
The table below details the technical parameters of the Rexroth R165111220 linear bearing block, providing critical data for engineers and procurement specialists. Each parameter is explained in plain engineering terms to clarify its significance in practical applications.
| Parameter | Value | Engineering Explanation |
|---|---|---|
| Nominal size | 15 mm | Indicates the standard size of the bearing block, ensuring compatibility with corresponding guide rails. |
| Format | FNS – flange, normal, standard height | Defines the block’s shape: flanged width, normal length, and standard height for versatile mounting. |
| Material | Carbon steel | High-strength material ensures durability and resistance to wear in demanding conditions. |
| Preload class | C1 – Low preload | Low preload reduces starting friction, ideal for smooth motion in precision applications. |
| Accuracy class | P – Precise | Precision accuracy ensures minimal deviation, critical for high-accuracy tasks. |
| Width of runner block | 47 mm (1.85 in) | Width dimension ensures stable mounting and load distribution. |
| Length of runner block | 58.2 mm (2.29 in) | Length impacts the block’s contact area with the rail, affecting stability. |
| Height of runner block | 19.9 mm (0.78 in) | Height determines vertical clearance and compatibility with system designs. |
| Dynamic load capacity C100 | 9860 N | Maximum dynamic load the block can handle over 100,000 m travel, per DIN ISO 14728-1. |
| Dynamic load capacity C50 | 12400 N | Dynamic load capacity for 50,000 m travel, offering higher ratings for shorter distances. |
| Static load capacity C0 | 12700 N | Maximum static load the block can withstand without deformation. |
| Maximum acceleration amax | 500 m/s² (1640 ft/s²) | Maximum acceleration the block can endure, reduced to 50 m/s² under specific load conditions. |
| Maximum permissible linear speed vmax | 5 m/s (16.4 ft/s) | Top speed for safe and reliable operation. |
| Permissible ambient temperature | -10 °C to +80 °C (14 °F to 176 °F), 100 °C (212 °F) briefly | Operating temperature range, with short-term tolerance for higher temperatures. |
| Friction coefficient μ | 0.002–0.003 | Low friction ensures energy efficiency and smooth motion without seal friction. |
| Weight | 0.2 kg (0.44 lb) | Lightweight design reduces system inertia, improving dynamic performance. |
