The Bosch Rexroth LINEAR-SET LSGE-B-12-DD (R106681240) is a high-quality linear motion set designed for precision applications. This linear set is composed of steel with an EB configuration and incorporates two seals for enhanced protection against contaminants. It features a standard precision housing made from lamellar graphite cast iron and a steel super linear bushing B, which does not have a self-alignment feature, ensuring stable and accurate guidance of the moving elements. With an adjustable design, this linear set includes integrated wiper seals on both sides to maintain cleanliness and reduce frictional drag when the system is not under radial load. The frictional drags are dependent on the speed of operation and the type of lubrication used. The shaft diameter 'd' falls within precise specifications, ensuring compatibility with corresponding components. The LINEAR-SET LSGE-B-12-DD has been designed to withstand dynamic loads with its dynamic load capacity C, which must be adjusted based on the direction of loading by applying specific factors for optimal performance. It can handle maximum accelerations (amax) efficiently while operating within a permissible ambient temperature range from -20°C to 80°C. Additionally, it has a notable outer diameter 'D', breakaway force specifications, and can achieve maximum permissible linear speeds (vmax), with the potential to reach up to 5 m/s under certain conditions. This product is characterized by its static load rating C, which like its dynamic counterpart, requires adjustment when loads are applied in non-primary directions. It comes clamped to the h shaft lower limit and is pre-set to zero-clearance for immediate use without additional adjustments. The weight of the unit is precisely measured at 0.7 kg. Designed for zero-clearance or preloaded guides, this model includes an adjusting screw that allows users to fine-tune radial clearance as needed. The Bosch Rexroth LINEAR-SET LSGE-B-12-DD represents a reliable solution for those in need of precise linear motion control in various applications without compromising performance or longevity.

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.
