The Bosch Rexroth LINEAR-SET LSADR1T-12-WV-900 (R109921285) is a state-of-the-art linear motion system designed for applications requiring high precision and rigidity. This linear set is composed of a lightweight precision tandem housing made from aluminum, ensuring an optimal strength-to-weight ratio. The system includes a precision steel shaft with one ball guide groove, which is accompanied by two torque-resistant linear bushings. These components are engineered for smooth and accurate linear motion. The LSADR1T-12-WV-900 features torquetransmitting, hardened steel bearing plates that are set to zero clearance ex works, offering exceptional stability against cocking loads. This particular model comes without external seals and is designed to be relubricatable, extending the maintenance intervals and service life of the system. The dynamic load capacity C indicates the minimal values under equal load conditions on both linear bushings, which speaks to the robustness of the design. This Bosch Rexroth Linear Set has been built to withstand maximum permissible linear speeds (vmax) and can operate within a wide range of ambient temperatures, making it versatile for various environmental conditions. The outer diameter D of the shaft ensures compatibility with corresponding equipment dimensions, while the mass m kg/m reflects its lightweight nature for ease of integration into existing systems. With its dynamic torsional moment load capacity Mt and static load rating C0, this product provides reliable performance under both dynamic and static conditions. The product group ID helps in identifying this particular series within the vast array of Bosch Rexroth linear motion products. Overall, the LINEAR-SET LSADR1T-12-WV-900 represents a high-quality solution for sophisticated linear motion requirements in various applications where precision and durability 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-R109921285-Linear set (aluminum), DRT1-12-WV-900, without seal

Note on lubrication:
