The Bosch Rexroth LINEAR-SET LSGF-M-50-DD (R108125000) is a high-quality linear motion system designed for precision and durability. This model features a flanged housing made from lamellar graphite cast iron, which provides robust support and alignment for the included standard linear bushing with wiper seals. The bushing assembly ensures smooth, clean linear motion thanks to the two seals that protect against contaminants. With a shaft diameter of 50mm, the R108125000 is engineered for use with corresponding shafts, allowing for precise radial clearance as denoted by the h shaft radial clearance specification. The system includes two retaining rings and two additional spacer rings made of steel, ensuring stable and secure mounting. This linear set is part of Bosch Rexroth's Standard metal series and is characterized by its normal version flange design. It offers a dynamic load capacity (C) that guarantees minimal value under various orientations and loading directions. Additionally, the breakaway force and maximum permissible linear speed (vmax) are specified to ensure optimal performance within its capabilities. The LINEAR-SET LSGF-M-50-DD is capable of withstanding a range of ambient temperatures from minimum to maximum as indicated in its specifications without compromising functionality or performance. Its design also accounts for frictional drags which may occur due to integrated wiper seals when not under radial load, providing insights into maintenance and operational expectations. This product has been carefully crafted to meet the needs of applications requiring vertical shaft designs and offers reliable performance in various environments. The weight specification indicates its suitability for designs where mass considerations are critical. Overall, this linear set represents Bosch Rexroth's commitment to delivering high-quality components for sophisticated linear motion applications.

1) Frictional drags generated by Linear Bushings with integrated wiper seals on two sides when not under radial load. The frictional drags depend on speed and lubrication.
2) Determined from working bore diameter and shaft tolerance statistics. When factoring in the outer diameter of the Linear Bushings and the housing bore, an h6 shaft produces similar radial clearance values as specified in the "H6H7" column under "Radial clearance" for the R0610 standard Linear Bushing.

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.
