The Bosch Rexroth LINEAR-SET LSAT-A-30-DD (R108563020) is a high-quality linear motion set designed for precision guiding and positioning tasks. This product features a lightweight precision tandem housing made of aluminum, which includes two super linear bushings A with external seals. The bushings are equipped with self-alignment features to ensure smooth operation and are relubricatable for easy maintenance. With a shaft diameter of 'd', the LINEAR-SET LSAT-A-30-DD is capable of handling dynamic load capacities, ensuring reliable performance under equal load conditions in the main direction of loading. Its design also accounts for situations where the loading direction varies, providing factors to adjust the load capacities accordingly. This linear set is characterized by its ability to sustain maximum acceleration and operate within a permissible ambient temperature range, ensuring durability and adaptability in various working environments. It has been tested for high-speed applications up to a certain limit while maintaining service life, highlighting its robustness against wear to plastic parts over significant travel distances. Moreover, the LINEAR-SET comes with integrated wiper seals on both sides that contribute to its friction force characteristics when not under radial load. The breakaway force and maximum permissible linear speed are specified to guide users on its operational limits. The Bosch Rexroth LINEAR-SET LSAT-A-30-DD is suitable for applications that require precise linear movement with easy installation. Its fixed working bore diameter ensures compatibility with specified components, offering versatility for different setups. Additionally, this model's availability as a Linear Motion Slide extends its application scope further, providing users with flexible options for their linear motion requirements. The unit's weight is noted at '.' kg, making it a manageable component within various systems where weight considerations are crucial.

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.
