The Bosch Rexroth LINEAR-SET LSAE-B-12-DD (R103681220) is a high-quality linear motion system designed for precision applications where smooth and accurate linear movement is required. This linear set comprises a lightweight precision aluminum housing and a super linear bushing B, which is adjustable and does not feature self-alignment, ensuring stable and precise motion. The shaft diameter d allows for compatibility with various design requirements, while the external seals provide protection against contaminants, extending the lifespan of the unit. Equipped with two integrated wiper seals on each side, the LINEAR-SET LSAE-B-12-DD reduces frictional drags which depend on speed and lubrication conditions. The set is relubricatable, allowing for maintenance that can prolong service life. Notably, this model has a maximum acceleration (amax), a specific range of permissible ambient temperatures from -20°C to 80°C, and an outer diameter D tailored to size H specifications. The unit comes with detailed load capacity information to ensure optimal performance under various loading directions. For instance, its dynamic load capacity C and static load rating C are stipulated for sizes E, H, M, N, L, and S. The breakaway force for size H and maximum permissible linear speed (vmax) are also provided to guide users in their applications. The LINEAR-SET is pre-adjusted to zero clearance or can be preloaded using an adjusting screw to modify radial clearance as per application requirements. It boasts an impressive service life with potential total travel ranging from 100 km to 1000 km without failure under specified conditions. Furthermore, its weight of 0.45 kg makes it suitable for applications where system mass is a critical factor. Overall, the Bosch Rexroth LINEAR-SET LSAE-B-12-DD stands out as a robust solution for precise linear guidance in various industrial applications where reliability and accuracy 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 .

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.
