The Bosch Rexroth LINEAR-SET LSGOE-A-20-DD (R106862040) is a high-quality linear motion set designed for precision movement and guidance. This product features an open, adjustable linear set made of steel, incorporating a spheroidal graphite cast iron precision housing and a super linear bushing A with self-alignment capabilities. The shaft diameter is carefully crafted to ensure smooth operation, while the integrated wiper seals on both sides maintain cleanliness and reduce frictional drag. Equipped with two seals for enhanced protection against contaminants, this linear set ensures reliability and longevity in various applications. The standard version boasts a dynamic load capacity that supports the main direction of loading, making it suitable for tasks requiring precise motion control. Moreover, it can handle maximum accelerations and operate within a wide range of ambient temperatures without compromising performance. The outer diameter is engineered to facilitate easy installation, while the breakaway force is optimized to ensure immediate response upon initiation of movement. The LINEAR-SET LSGOE-A-20-DD can achieve maximum permissible linear speeds, with the caveat that higher speeds may limit service life due to increased wear on plastic components. Designed for zero-clearance or preloaded guides, this product comes clamped to the h6 shaft lower limit and set to zero-clearance out of the box. An adjusting screw allows users to fine-tune radial clearance according to specific requirements. With its robust build and versatile features, this Bosch Rexroth linear set is ideal for applications demanding precise linear guidance with easy adjustability and maintenance.

Impact of load direction on load rating of open Linear Bushings
The load ratings C and C0 apply for the main direction of loading ρ = 0°. For all other load directions, the load ratings must be multiplied by the factors fρ (dynamic load rating C) or fρ0 (static load rating C0).
Installing specific Linear Bushings can prevent reductions in load capacity (see Linear Set with side opening).
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 .
| 1) | fs = factor |
| 2) | s = movement path |
Reduced load capacity with high load
If the load F on a Super Linear Bushing A is more than F > 0.5 x C, the dynamic load rating C decreases.
Definition of dynamic load ratings
Self-alignment feature
The self-alignment feature in the steel bearing plates and machined ball guide grooves ensure quieter travel. The flow chart shows a comparison with a conventional Linear Bushing. The example is based on a load of 800 N and misalignment of about 8 ft (caused by shaft deflection).
Due to the self-alignment feature, two super Linear Bushings must be used on at least one of the shafts in the guide.

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.
