The Bosch Rexroth LINEAR-SET LSGE-B-50-DD (R106685040) is a high-precision linear motion component designed for various applications requiring accurate and smooth linear movement. This linear set is constructed from steel with a precision housing made of lamellar graphite cast iron, featuring a super linear bushing B that does not include a self-alignment feature. The set includes two integrated wiper seals for protection against contaminants, ensuring long-lasting performance and reliability. With a shaft diameter of 50 mm, this model offers standard precision and is adjustable to meet specific application requirements. It is equipped with an adjusting screw for radial clearance adjustments, allowing it to be clamped to the h shaft's lower limit and set to zero-clearance or preloaded as needed. The LINEAR-SET LSGE-B-50-DD boasts an impressive dynamic load capacity (C) and has been tested for total travel distances significantly exceeding industry standards without failure. The maximum acceleration (amax) it can handle, along with its permissible ambient temperature range, ensures versatility across different working environments. The outer diameter (D), breakaway force, and maximum permissible linear speed (vmax) are specified to cater to demanding applications. Notably, this linear set has a static load rating (C) that indicates its ability to withstand loads in the main direction of loading. For non-main direction loads, the capacities must be adjusted using specified factors. Additionally, the friction force generated by this model under various conditions is detailed in the specifications. Designed for ease of use and maintenance, the Bosch Rexroth LINEAR-SET LSGE-B-50-DD provides reliable performance in precision applications where zero-clearance or preloaded guides are required. Its weight ensures it can be integrated into systems without adding excessive bulk or compromising on functionality.

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.
