The Bosch Rexroth LINEAR-SET LSGF-M-20 (R108112000) is a high-quality linear set designed for precise linear motion applications. This set features a flanged housing made of lamellar graphite cast iron, providing robust support and alignment for the included standard linear bushing with wiper seals. The bushing ensures smooth, clean motion due to its ability to wipe away debris. With a shaft diameter of 20mm and no seal, this Linear-Set offers flexibility in various environments. The radial clearance is not adjustable but has been optimized for this size V unit to achieve similar radial clearance values as specified in the hH column under Radial clearance for the R standard linear bushing. The product is equipped with two retaining rings and two additional spacer rings made of steel, which ensure secure positioning on the shaft. It also features a breakaway force that allows for reliable operation even after periods of static positioning. Designed to withstand a dynamic load capacity C and static load rating C, this unit can handle significant loads while maintaining performance—ideal for applications where load orientation and direction may vary. The permissible ambient temperature range from -20°C to +80°C makes it suitable for diverse working environments. The LINEAR-SET LSGF-M-20 is capable of maximum acceleration and can reach a maximum permissible linear speed vmax, ensuring efficient operation in high-speed applications. Its design also minimizes frictional drags when not under radial load, which are influenced by factors such as speed and lubrication conditions. This product group ID falls within the category of Linear Sets with standard Linear Bushings, flanged type, particularly suited for vertical shaft configurations in modular systems. With its weight carefully considered during design, this Bosch Rexroth Linear Set combines durability with precision engineering to facilitate reliable linear motion solutions.

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.

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 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.
