The Bosch Rexroth LINEAR-SET LSGF-M-25-DD (R108122500) is a high-quality linear set made of steel with a flange design, tailored for precise linear motion applications. This set includes a standard LB metal linear bushing equipped with wiper seals, ensuring clean operation by preventing the ingress of contaminants. The flanged housing is constructed from lamellar graphite cast iron, offering robust support and alignment for the system. Designed for ease of installation, this linear set comes with two retaining rings and additional spacer rings made of steel, suitable for shaft diameters, providing a secure fit and maintaining the integrity of the setup. The radial clearance is not adjustable, but the standard h shaft radial clearance ensures similar values to those specified in the hH column under Radial clearance for R standard linear bushings. This product operates efficiently within a permissible ambient temperature range of -20°C to +80°C. It boasts an impressive dynamic load capacity and static load rating that are minimal values due to potential variations in loading orientation and direction. The LINEAR-SET LSGF-M-25-DD ensures low frictional drag under no radial load conditions, which varies with speed and lubrication levels. The set's size V corresponds to its foot dimensions while size E denotes its outer diameter. It features a breakaway force that guarantees smooth initiation of movement and supports a maximum permissible linear speed vmax. Weighing in at just 1 kg, this linear guide system promises both lightweight design and robust performance. Overall, the Bosch Rexroth LINEAR-SET LSGF-M-25-DD is an optimal solution for vertical shaft designs requiring precise guidance and reliable operation in various industrial applications where contamination exclusion and durability 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.

Radial clearance
The radial clearance values shown in the table have been determined from statistics and correspond to values expected in practice. The R1066, R1068 and R1072 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.
General mounting instructions
Linear sets with standard Linear Bushings do not come with initial lubrication. Grease the Linear Bushings before use. Service life data is based on initial lubrication and relubricated Linear Bushings.
