The Bosch Rexroth LINEAR-SET LSADR2T-25-WV-1200 (R109952587) is a high-precision linear motion set designed for applications requiring precise and smooth linear movement. This product features a lightweight precision tandem housing made from aluminum and includes a precision steel shaft with two ball guide grooves. The inclusion of two torque-resistant linear bushings provides stability against cocking loads, while the torquetransmitting, hardened steel bearing plates are set to zero clearance ex works for optimal performance. With its standard length as per the provided table, the shaft diameter 'd' ensures compatibility with various applications. The lack of an external seal indicates that this model is intended for environments where additional sealing is not necessary, which can be advantageous in terms of reducing friction and maintenance requirements. Nevertheless, the system remains relubricatable, which is essential for long-term operation and ease of maintenance. The LINEAR-SET LSADR2T-25-WV-1200 boasts impressive mechanical properties including a dynamic load capacity 'C' that ensures reliable performance under equal load conditions on both bushings. Its design accommodates maximum acceleration 'amax' and operates within a permissible ambient temperature range, ensuring versatility across different working environments. Additionally, the outer diameter 'D', size 'E', and weight specifications underscore its suitability for various installation spaces and applications. This linear set's capability to handle both dynamic loads as well as static load capacity 'C' makes it an ideal choice for applications where high precision and rigidity are paramount. Furthermore, the dynamic torsional moment load capacity 'Mt' highlights its ability to withstand torsional forces during operation. As part of Bosch Rexroth's Series Torque Productgroup ID, this linear set represents a combination of advanced engineering and robust construction suitable for demanding linear motion tasks.

Reduced load capacity with short stroke
In case of short stroke, the service life of the shaft is less than that of the torque-resistant Linear Bushing. The dynamic load ratings C in the tables must therefore be multiplied by the factor fs .

Initial lubrication
Torque-resistant Linear Bushings do not come with initial lubrication. Grease Linear Bushings before use, see "Initial lubrication" in the "Lubrication" section.
Service life data is based on initial lubrication and relubricated Linear Bushings.
Lubricating a Linear Set with a torque-resistant compact Linear Bushing: on-shaft via Ø = 3.9 lubricating hole until lubricant seeps out. Lubricating a tandem Linear Set: on-shaft via recirculating lubricating groove in middle of outer diameter until lubricant seeps out. Lubricating a flanged Linear Set: on-shaft via funnel-type lube nipple recessed on the end face until lubricant seeps out.
