The Bosch Rexroth LINEAR-SET LSADR2T-25-WV-900 (R109952585) is a high-precision linear motion system designed to provide smooth and accurate linear movement in various applications. This linear set features a lightweight precision tandem housing made of aluminum, which houses two torque-resistant linear bushings. These bushings are paired with a precision steel shaft that includes two ball guide grooves, ensuring stable and precise motion. The system is characterized by its torquetransmitting, hardened steel bearing plates, which are set to zero clearance ex-factory to maximize accuracy and rigidity. The design offers excellent stability against cocking loads, making it suitable for applications requiring high precision under dynamic conditions. The LSADR2T-25-WV-900 is capable of withstanding dynamic load capacities as specified by the manufacturer and can operate at maximum permissible ambient temperatures within the range provided in the specifications. Notably, this model does not include external seals but remains relubricatable for ease of maintenance. Its dynamic torsional moment load capacity ensures that it can handle the demands of various applications while maintaining performance. The absence of seals also contributes to the system's lightweight design, reducing overall mass and making it easier to integrate into machinery. The outer diameter and size specifications are tailored to meet common industry standards, allowing for compatibility with a wide range of equipment. Additionally, the Bosch Rexroth LINEAR-SET is equipped with the capability to handle maximum acceleration and linear speeds as detailed in its technical specifications. Overall, this product is well-suited for applications where precise linear motion is critical and where components must resist torsional forces without compromising on weight or ease of maintenance. Its robust construction and thoughtful engineering make it an ideal choice for those seeking reliable linear motion solutions.

1) Load rating when both Linear Bushings are under equal load. The load ratings indicated are minimal values as the load direction cannot always be clearly defined.
The load ratings are based on a total travel of 100, 00 m. When based on 50 000 m, the  values in the table need to be multiplied by 1.26.

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 .

Installation

The Linear Sets come preassembled and set to zero clearance. When pulling out the shaft, the adjusting screws must be loosened and the torque-resistant Linear Bushing reset.

General mounting instructions

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. technical illustration-R109952585-Linear set (aluminum), DRT2-25-WV-900, without seal
