***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth LINEAR-SET LSADR2-20-WV-1200 (R109852087) is an advanced linear motion product designed for precision applications requiring high levels of torque resistance and stability. This linear set is comprised of a lightweight precision tandem housing made from aluminum, which contributes to the overall durability and reduced system weight. It features a precision steel shaft with two ball guide grooves that ensure smooth and accurate linear movement. The torqueresistant linear bushing included in this set is engineered to handle dynamic loads efficiently, with hardened steel bearing plates set to zero clearance by the manufacturer to guarantee optimal performance. These plates are specifically designed to transmit torque while maintaining stability against cocking loads that can occur during operation. The LSADR2-20-WV-1200 does not include external seals, but it is relubricatable, offering ease of maintenance and extended service life. With its robust construction, the LINEAR-SET LSADR2-20-WV-1200 can withstand a dynamic load capacity as specified by Bosch Rexroth's minimal values, taking into account that the direction of loading may not always be clearly defined. It also boasts a significant dynamic torsional moment load capacity (Mt), which indicates its ability to resist twisting forces under dynamic conditions. This product operates effectively within a specified range of ambient temperatures and can accommodate maximum acceleration (amax) without compromising functionality or lifespan. Its design ensures compatibility with high linear speeds while maintaining precise control over movement. The outer diameter (D), size (E), size (H), and size (L) dimensions are standardized according to Bosch Rexroth's specifications, ensuring compatibility with various applications. The weight of the unit is kept at an optimal level considering its robustness and load capacities. In summary, the Bosch Rexroth LINEAR-SET LSADR2-20-WV-1200 is tailored for applications requiring precise linear motion with high torque resistance, offering exceptional performance in terms of stability, load capacity, and maintenance convenience.

1) 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 .

Life expectancy calculation

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-R109852087-Linear set (aluminum), DR2-12-WV-1200, without seal
