The Bosch Rexroth LINEAR-SET LSA-B-25-DD (R103582520) is a high-quality linear set designed for precision guiding applications that require a fixed working bore diameter. This particular model features a lightweight precision aluminum housing and comes equipped with a super linear bushing B without a self-alignment feature, which is ideal for applications where alignment control is managed externally or not required. The set includes external seals and offers the capability to be relubricated, ensuring long-lasting performance and reduced maintenance needs. The shaft diameter 'd' of this linear set is meticulously manufactured to ensure smooth motion and high accuracy in linear movements. It has been built to withstand dynamic load capacities while maintaining efficiency, as indicated by the specific factors provided for different shaft diameters. The LINEAR-SET LSA-B-25-DD can handle maximum accelerations (amax) and operates reliably within an ambient temperature range of -20°C to 80°C. With an outer diameter 'D', this model exhibits an impressive breakaway force, reflecting its robustness in starting motion under load. It also boasts a significant maximum permissible linear speed (vmax), highlighting its ability to support high-speed applications while still providing precise guidance. The static load rating 'C' further assures the user of its capacity to sustain loads without compromising on performance. Bosch Rexroth has also considered the total service life of the product, with tests showing substantial travel distances without failure, ensuring durability and reliability in long-term use. Additionally, the friction force generated by the integrated wiper seals on both sides remains low even when not under radial load, contributing to smoother operation. This model's weight has been optimized for ease of installation without sacrificing strength or performance, making it suitable for various precision guide applications. The LINEAR-SET LSA-B-25-DD is part of Bosch Rexroth's product group ID that signifies its commitment to quality and innovation in linear motion technology.

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 .

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.
