The Bosch Rexroth LINEAR-SET LSGF-M-20-DD (R108122000) is a meticulously engineered linear motion component designed for precise and smooth linear movement. This linear set is constructed from steel, featuring a flange configuration and standard LB metal for robustness and durability. It comes equipped with two seals to ensure protection against contaminants, enhancing the longevity of the system. With a shaft diameter of 20mm, this product includes two retaining rings and additional spacer rings made of steel, which are essential for maintaining the integrity of the shaft assembly. The radial clearance is non-adjustable, with size V specifications providing an optimal fit for various applications. The LINEAR-SET LSGF-M-20-DD has been crafted to deliver consistent performance with a normal flanged housing made from lamellar graphite cast iron and a standard linear bushing that incorporates wiper seals. This product is designed to accommodate a dynamic load capacity (C) that signifies minimal values due to varying orientations and loading directions. It can withstand maximum accelerations (amax), with permissible ambient temperatures ranging from -...°C to ...°C. The outer diameter (D) aligns with size E standards, ensuring compatibility with corresponding equipment. The breakaway force and maximum permissible linear speed (vmax) are indicative of the product's capability to handle high-demand applications without compromising on efficiency or reliability. The static load rating (Co) reflects the unit's ability to sustain loads without motion, while the friction force denotes resistance encountered during operation. Weighing in at ..., this Bosch Rexroth Linear Set serves as an integral part of systems requiring vertical shaft alignment. Its dynamic load capacity further underscores its suitability for various applications where precision linear guidance is paramount. Overall, this product stands out for its construction quality, performance specifications, and adaptability in diverse operating conditions.

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.
