The Bosch Rexroth LINEAR-SET LSGE-B-25-DD (R106682540) is a high-quality linear set composed of steel with an EB configuration and includes two integrated wiper seals. This linear set is designed for precision applications, featuring a standard precision housing made from lamellar graphite cast iron and a steel super linear bushing B without a self-alignment feature. The shaft diameter 'd' ensures compatibility with corresponding components, while the outer diameter 'D' is tailored to meet specific design requirements. The LINEAR-SET LSGE-B-25-DD offers an adjustable setup, allowing for zero-clearance or preloaded guides through its adjusting screw, which is particularly useful for applications demanding high precision and rigidity. The integrated wiper seals contribute to the unit's maintenance by preventing contamination and ensuring longevity. This model boasts impressive mechanical properties, including a dynamic load capacity 'C', which is critical for understanding the forces it can withstand during operation. Designed to accommodate maximum accelerations 'amax' and operate within a permissible ambient temperature range, this linear set ensures reliable performance in various working conditions. It also has specified breakaway forces and maximum permissible linear speeds 'vmax', highlighting its capability to handle rapid movements without compromising stability or service life. This product's static load rating 'C' indicates its ability to sustain loads without movement, which is essential for static or slow-moving applications. The radial clearance comes clamped to the h shaft lower limit and set to zero-clearance as a default configuration, streamlining installation and setup processes. Overall, the Bosch Rexroth LINEAR-SET LSGE-B-25-DD (R106682540) serves as an integral component in linear motion systems where precision, durability, and adjustability are paramount. Its robust construction and meticulous design cater to demanding industrial applications that require reliable linear guidance with minimal maintenance.

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.
