The Bosch Rexroth LINEAR-SET LSAT-A-25-DD (R108562520) is a high-quality linear motion set designed for precision applications requiring smooth and accurate linear movement. This set includes a lightweight precision tandem housing made of aluminum, which houses two super linear bushings A, known for their self-alignment feature, ensuring reliable operation and extended life span. The unit comes with external seals and is relubricatable, offering maintenance ease for various operational conditions. With a shaft diameter of "d," the LINEAR-SET LSAT-A-25-DD is equipped to handle dynamic load capacities with equal load distribution across the bushings. It features a maximum acceleration (amax), and it operates efficiently within a permissible ambient temperature range. The outer diameter "D" is suited for the specified size H of the unit. This linear set boasts an impressive breakaway force and can achieve maximum permissible linear speeds (vmax), with potential speeds reaching up to 5 meters per second under certain conditions. Service life estimates are robust, with tests indicating significant travel distances without failure. Users will appreciate the precise control offered by this system, thanks to its low frictional drag when not under radial load. The static and dynamic load capacities are optimized for the main direction of loading; however, if loading occurs in other directions, capacity factors must be adjusted accordingly as specified in the product details. Additionally, this model provides dynamic and static longitudinal moment load capacities that cater to various application requirements. Weighing in at just .kg, the LINEAR-SET LSAT-A-25-DD is an ideal choice for applications where weight is a consideration without compromising on strength or performance. It also offers flexibility in use as it's available as a Linear Motion Slide, further enhancing its adaptability to different operational setups. Designed for fixed working bore diameters, this linear set ensures easy installation for precision guides where accuracy and reliability are paramount.

Impact of load direction on load rating of closed Linear Bushings
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 shaft is less than that of the super Linear Bushing. The load ratings C specified in the tables must therefore be multiplied by the factor f.s .
| 1) | fs = factor |
| 2) | s = movement path |
Reduced load capacity with high load
If the load F on a Super Linear Bushing A is more than F > 0.5 x C, the dynamic load rating C decreases.
Definition of dynamic load ratings
Self-alignment feature
The self-alignment feature in the steel bearing plates and machined ball guide grooves ensure quieter travel. The flow chart shows a comparison with a conventional Linear Bushing. The example is based on a load of 800 N and misalignment of about 8 ft (caused by shaft deflection).
Due to the self-alignment feature, two super Linear Bushings must be used on at least one of the shafts in the guide.

Radial clearance
The radial clearance values shown in the table have been determined from statistics and correspond to values expected in practice. The adjustable Linear Sets come clamped to an h5 shaft (lower limit) and set to zero clearance.
Vertical dimension
The tolerance values for the vertical dimension "H" for the Linear Sets shown in the table have been determined from statistics and correspond to values expected in practice.
Bolts
We recommend bolts in accordance with ISO 4762-8.8 for fastening the Linear Sets.
Lubrication
On-shaft relubrication on relubricatable Linear Bushing only until lubricant seeps out.
