The Bosch Rexroth LINEAR-SET LSACT-25-DD-NR-G (R102922534) is a high-quality linear motion system designed for precision applications. This linear set is composed of lightweight precision tandem housing made from aluminum and includes two compact linear bushings, designated as KBCNR, which are integrated with wiper seals. The system is characterized by its rust-resistant construction and comes pre-lubricated with Dynalub for reduced maintenance needs. The LSACT-25-DD-NR-G features a closed format for the linear bushings, ensuring protection against contaminants and extending the lifespan of the set. Its shaft diameter 'd' allows for smooth motion, while the dual seals provide additional protection against debris. The product has been engineered to accommodate a maximum acceleration (amax), and it operates effectively within a specified range of ambient temperatures. Notably, this linear set offers both dynamic load capacity (C) and static longitudinal moment load capacity (ML), making it suitable for various loading scenarios. The friction force generated by this model is dependent on speed and lubrication but remains minimal due to its design when not under radial load. Size specifications such as E, H, L, and N are provided to detail various aspects like breakaway force, maximum permissible linear speed (vmax), static load rating (C), and weight. Overall, the Bosch Rexroth LINEAR-SET LSACT-25-DD-NR-G is an optimal solution for users needing precise linear motion control in their applications. Its robust design ensures reliable performance under various conditions without sacrificing efficiency or accuracy.

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 .
