The Bosch Rexroth LINEAR-SET LSATE-A-25-DD (R103262520) is a high-precision linear motion set designed for various applications requiring smooth and accurate guidance. This set features lightweight precision tandem housing made from aluminum, which includes two super linear bushings A with a self-alignment feature. The shaft diameter 'd' ensures compatibility with corresponding components, while the inclusion of two external seals offers protection against contaminants, enhancing the longevity of the system. This linear set is capable of handling dynamic load capacities and static load ratings efficiently, as specified in the detailed size charts provided by Bosch Rexroth. It allows for maximum acceleration and can operate within a permissible ambient temperature range, ensuring reliable performance in diverse working conditions. The outer diameter 'D' and size specifications cater to different requirements, providing flexibility for integration into multiple setups. The LINEAR-SET LSATE-A-25-DD comes with an adjustable feature for zero-clearance or preloaded guides through an adjusting screw that modifies radial clearance. This adjustability allows users to fine-tune the system for optimal performance based on specific application needs. Additionally, it is relubricatable, which contributes to reduced maintenance time and costs. With its ability to handle significant frictional drags without radial load and its compatibility with high speeds—up to a certain limit before wear on plastic parts becomes a factor—this linear set demonstrates versatility across various applications. The product also boasts impressive moment load capacities both in dynamic and static states. Overall, this Bosch Rexroth linear set is engineered for efficiency and precision in linear motion tasks, offering robust construction and customization options suitable for a wide range of industrial uses. Its weight specifications further emphasize its design for ease of integration without sacrificing performance or durability.

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 .
| 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.
