The Bosch Rexroth LINEAR-SET LSGF-B-20-DD (R108182040) is a high-quality linear set composed of steel with a flange design, featuring the Super LB B linear bushing without self-alignment capability. This precision-engineered component has a standard shaft diameter 'd' and is equipped with two integrated wiper seals to ensure protection against contaminants. The set includes two retaining rings and additional spacer rings made of steel, designed for use with corresponding shaft diameters. This linear set from Bosch Rexroth is characterized by its standard precision flanged housing made of lamellar graphite cast iron and super linear bushing B, which does not have a self-alignment feature. It offers a friction force categorized under Size V, with the frictional drags being dependent on speed and lubrication conditions. Notably, this product does not come with initial lubrication. The LINEAR-SET LSGF-B-20-DD operates within an ambient temperature range of -20°C to +80°C and can handle a maximum acceleration 'amax'. Its dynamic load capacity 'C' is indicative of the product's ability to withstand operational demands over time. Additionally, it has a static load rating 'C', suitable for applications requiring stability under stationary loads. With an outer diameter 'D', this linear set provides precise guidance for vertical shaft applications and boasts a maximum permissible linear speed 'vmax'. The service life expectancy varies based on usage intensity but tests have indicated significant travel distances without failure. Weighing in at 1.5 kg, this modular unit complements other products in the Linear Set series by Bosch Rexroth and is tailored for designs that necessitate robust vertical 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.
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 .

| 2) | s = movement path |

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.
Lubrication
On-shaft relubrication on relubricatable Linear Bushing only until lubricant seeps out.
