The Bosch Rexroth LINEAR-SET LSA-B-12-DD (R103581220) is a high-quality linear set comprised of an aluminum housing with a precision super linear bushing B, designed for applications requiring precise linear motion. This product features a closed format with external seals and is relubricatable, ensuring long-term performance and minimal maintenance. The shaft diameter d is fixed, providing a secure fit and straightforward installation. Equipped with two seals, the LINEAR-SET LSA-B-12-DD offers protection against contaminants, enhancing the durability of the system. The standard version of this linear set does not include a self-alignment feature, which means that it requires precise alignment during installation to ensure optimal performance. The lightweight aluminum housing contributes to the overall reduction in system weight without compromising strength or reliability. This linear set is capable of handling dynamic loads effectively, as indicated by its dynamic load capacity C. However, users should note that if the load direction differs from the main direction of loading, adjustments to the load capacities must be made using specified factors. This ensures that the product can sustain various loading conditions without compromising its structural integrity. The LINEAR-SET LSA-B-12-DD can operate within a wide range of ambient temperatures and is capable of achieving high speeds up to a maximum permissible linear speed vmax. Its design includes considerations for maximum acceleration amax and static load rating C for different sizes within the range. Overall, this linear guide system is suitable for applications where precise and reliable linear movement is critical. With its robust construction and thoughtful design features like friction force consideration and breakaway force requirements for size H, it offers an efficient solution for precision guides in various settings while maintaining ease of installation due to its fixed working bore diameter. The product's weight further enhances its appeal by contributing to more streamlined machine designs.

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 .

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.
