The Bosch Rexroth LINEAR-SET LSGO-B-20-DD (R106782040) is a high-precision linear motion system designed to facilitate smooth and accurate linear movement in various applications. This linear set is constructed from steel and features an open design, which includes a spheroidal graphite cast iron precision housing and a steel super linear bushing B without a self-alignment feature. The shaft diameter 'd' ensures compatibility with corresponding components, while the integrated wiper seals on both sides maintain cleanliness and protect against contaminants. The system is secured with a locating screw, ensuring stability and precision during operation. It is characterized by standard precision, offering reliable performance for demanding tasks. The model boasts an impressive dynamic load capacity 'C', which signifies its ability to handle substantial loads effectively in the main direction of loading. Notably, the LINEAR-SET LSGO-B-20-DD can operate within a wide temperature range, ensuring its functionality across diverse working environments. Its outer diameter 'D' is tailored to fit seamlessly into existing assemblies or new designs. Additionally, the product has been tested for durability, demonstrating significant travel distances without failure, highlighting its robustness and longevity. This linear set's low friction force contributes to efficient motion with minimal resistance when not under radial load. However, it's important to note that the maximum permissible speed 'vmax' should be adhered to for optimal service life; higher speeds are possible but may lead to increased wear on plastic parts. With a weight of only 0.7 kg, this Bosch Rexroth linear set provides an excellent balance between strength and ease of handling. It is ideal for long guides that require shaft support and exhibit high levels of rigidity, making it suitable for applications where precise linear motion is paramount.

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 .

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.
