The Bosch Rexroth LINEAR-SET LSGE-B-20-DD (R106682040) is a high-precision linear motion set designed to provide smooth and accurate guidance in various applications. This linear set is crafted from steel and includes a precision housing made of lamellar graphite cast iron, ensuring durability and robustness for long-term use. The set features a super linear bushing B that does not have a self-alignment feature, which contributes to the system's stability and precision. Equipped with integrated wiper seals on both sides, the LINEAR-SET LSGE-B-20-DD ensures protection against contaminants, thereby prolonging the life of the system. The shaft diameter 'd' of this model allows for a secure fit with corresponding components. It's important to note that this model comes clamped to an h6 shaft lower limit and is pre-set to zero-clearance, which can be adjusted if necessary via an adjusting screw for radial clearance. With its standard size V series Super B no self-alignment feature, this linear set exhibits low friction force under no radial load conditions, as indicated by the footnote regarding friction force FR. The dynamic load capacity 'C' is specified for the main direction of loading but can be adjusted by certain factors if the loading direction varies. This model also boasts a high static load rating 'C', making it suitable for applications where heavy loads are involved. The permissible ambient temperature range for operation extends from -20°C to +80°C, allowing it to function effectively in various environmental conditions. Additionally, it has been tested for total travel ranging from 100 km² to 1000 km² without failure, indicating its reliability over extensive use. With its adjustable features and zero-clearance delivery state, this linear set is ideal for applications requiring precise linear motion control with minimal maintenance needs.

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 .

Life expectancy calculation

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.
