The Bosch Rexroth ELINE LINEAR SET (R102925444) is a high-precision linear motion set designed to facilitate smooth and accurate linear movements in various applications. This product features a lightweight precision tandem housing made from aluminum, which includes two eLINE linear bushings. The set is characterized by its compact design, with a closed format of linear bushings that ensures durability and reliable performance. The ELINE LINEAR SET is equipped with integrated wiper seals on both sides, which serve to protect the internal components from contaminants while maintaining the integrity of the system's lubrication. The reduced radial clearance and initial lubrication with Dynalub contribute to the set's low friction force and breakaway force, optimizing its efficiency for motion control tasks. Designed for ease of use, this linear set boasts a shaft diameter d that fits seamlessly with corresponding components. It comes greased as standard, reducing maintenance requirements and ensuring longevity. The dynamic load capacity C and static load rating C0 are indicative of the set's ability to handle significant loads in its main direction of loading. Adjustments can be made for loads applied in non-primary directions by applying specific factors. This system can withstand a maximum acceleration (amax) and operates within a permissible ambient temperature range, showcasing its adaptability to various working environments. Its outer diameter D is tailored to fit within compact spaces without sacrificing performance. With its robust construction and meticulous engineering, the Bosch Rexroth ELINE LINEAR SET (R102925444) is suitable for applications requiring precise linear guidance with minimal frictional resistance. Its compatibility with high-speed operations and ability to sustain heavy loads make it an ideal choice for industrial automation systems where accuracy and reliability are paramount.

| 1) | The load ratings apply for the main direction of loading. If the load direction is not the main direction of loading, the load ratings must be multiplied by the following factors: Ø d 12 and 16: f = 0,90, f0 = 0.86, Ø d 20 to 50: f = 0.79, f0 = 0.68 |
| The load ratings are based on a total travel of 100, 00 m. When based on 50 000 m, the values in the table need to be multiplied by 1.26. |

Effect of load direction on load rating
The listed load ratings should be chosen depending on installation in minimum or maximum position and should be based on the calculations. If the load direction is clearly defined and the Linear Bushings can be installed in maximum position, the load ratings Cmax. (dynamic load rating) and C0 max (static load rating) can be used. If aligned installation is not possible or the load direction is not defined, the minimum load ratings must be used.
Reduced load capacity with short stroke
In case of short stroke, the service life of the shafts is less than that of Linear Bushings. The load ratings C specified in the tables must therefore be multiplied by the factor f.s .

| 2) | s = stroke |
