The Bosch Rexroth LINEAR-SET LSG-B-50-DD (R106585040) is a high-quality linear set designed for precision motion applications. This robust assembly features a closed steel configuration with integrated wiper seals, ensuring reliable operation by preventing the ingress of contaminants. The linear set is constructed from lamellar graphite cast iron and includes the super LB B linear bushing, which is known for its high load capacities and precise movement. With a shaft diameter of 50mm, this model provides sturdy support for linear motion tasks without the need for self-alignment features. The standard precision housing contributes to the overall rigidity and performance of the system. This LINEAR-SET is especially suitable for applications requiring controlled friction force (FR), as it maintains consistent frictional drags even when not under radial load, with values dependent on speed and lubrication conditions. The dynamic load capacity (C) of this model accounts for the main direction of loading; however, if loads are applied in non-primary directions, the capacity must be adjusted using specified factors. It can handle maximum accelerations (amax) efficiently and operates within an ambient temperature range of -20°C to 80°C without compromising performance. This LINEAR-SET has a substantial outer diameter that facilitates a breakaway force tailored to meet demanding operational requirements. Additionally, it boasts an impressive static load rating (C), ensuring stability and longevity under constant loads. With its size V series designation and lack of self-alignment feature, this Bosch Rexroth product excels in applications where precision alignment is managed externally or inherently within the system design. The weight specifications indicate that it is robust yet manageable for various installations. Overall, the Bosch Rexroth LINEAR-SET LSG-B-50-DD is tailored for users seeking a reliable and precise linear motion solution that balances performance with durability in challenging industrial settings.

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 .

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 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.
