***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 LSADR1T-20-WV-1200 (R109922087) is a high-quality linear motion set designed for precision applications requiring robustness and resistance to torque loads. This linear set includes a lightweight precision tandem housing made of aluminum, which houses two torque-resistant linear bushings. These bushings are paired with a precision steel shaft featuring one ball guide groove, ensuring smooth and accurate linear motion. The shaft diameter 'd' and the standard length conform to the specifications in the provided table, while the absence of an external seal contributes to the product's streamlined design. The bearing plates are hardened steel, set to zero clearance ex-factory, which allows for precise movements without play. This configuration provides stability against cocking loads and is capable of transmitting torque effectively. Furthermore, this linear set is relubricatable, extending its service life by allowing for maintenance and lubrication as needed. The dynamic load capacity 'C' indicates that it can handle significant loads when both bushings are under equal load, although these values are minimal since the direction of loading may vary. Designed for applications with specific environmental conditions, this product can operate within a permissible ambient temperature range from 'min temperature' to 'max temperature'. Its outer diameter 'D', maximum permissible linear speed 'vmax', and mass 'm kg/m' have been meticulously calculated to ensure optimal performance within its intended operational parameters. In summary, the Bosch Rexroth LINEAR-SET LSADR1T-20-WV-1200 is tailored for applications that demand high precision and resistance to torsional forces. Its construction quality and design features make it suitable for various uses where reliability and accuracy are paramount.

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-R109922087-Linear set (aluminum), DRT1-12-WV-1200, without seal

Note on lubrication:
