The Bosch Rexroth LINEAR-SET LSACT-25-DD-G (R102922544) is a high-precision linear motion set designed to facilitate smooth and accurate linear movement in various applications. This linear set comprises lightweight precision aluminum housing, two compact linear bushings, integrated wiper seals for protection against contaminants, and is pre-greased for immediate use. The closed format of the bushings ensures enhanced rigidity and durability. With a shaft diameter of 25 mm, the LSACT-25-DD-G is engineered for optimal performance under normal radial clearance conditions. The initial lubrication with Dynalub minimizes friction and wear, extending the service life of the component. The integrated wiper seals contribute to a consistent friction force (FR), even when not under radial load, which is essential for maintaining precise control over movement. The dynamic load capacity (C) and static load rating are indicative of the product's ability to withstand forces during operation. These capacities are based on the main direction of loading; however, they can be adjusted by specific factors if the load direction varies. The product can handle maximum accelerations and operate within a wide range of permissible ambient temperatures, making it versatile for different working environments. Additionally, this linear set boasts an impressive breakaway force and can achieve high maximum permissible linear speeds (vmax). Its design ensures that it can endure significant static longitudinal moment load capacities (ML), further highlighting its robustness. The LINEAR-SET LSACT-25-DD-G is part of Bosch Rexroth's Compact Series and comes in various sizes denoted by E, H, L, and N, each with its own specific attributes tailored to meet diverse application needs. Its weight has been optimized to contribute to the overall efficiency of the system in which it is installed. This product is ideal for those seeking a reliable linear guidance system that promises precision and longevity without excessive maintenance requirements.

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 .
