The Bosch Rexroth LINEAR-SET LSADR2T-50-WV-2000 (R109955088) is a high-precision linear motion set designed for applications requiring smooth and accurate linear movements. This set features a lightweight precision tandem housing made from aluminum, ensuring a robust yet nimble solution for various motion tasks. It is equipped with a precision steel shaft with two ball guide grooves, sized at 50mm in diameter, which comes in a standard length as per the manufacturer's specifications. The LSADR2T-50-WV-2000 includes two torque-resistant linear bushings that have been meticulously engineered to handle torsional loads while maintaining zero clearance thanks to pre-set hardened steel bearing plates. This design provides exceptional stability against cocking loads, vital for maintaining precision in demanding applications. The set also offers the convenience of being relubricatable, extending the lifespan of the components through regular maintenance. With an ability to operate within a wide range of temperatures, from minimum to maximum permissible ambient temperatures as specified by Bosch Rexroth, this linear set ensures reliable performance in diverse working environments. The product is capable of handling dynamic load capacities and static load ratings that are indicative of minimal values due to variable loading directions. Moreover, the LSADR2T-50-WV-2000 can achieve impressive accelerations and speeds while maintaining its integrity under load, thanks to its dynamic torsional moment load capacity. Despite its robustness and capability, it maintains a modest mass that contributes to its efficiency and ease of integration into various systems. Overall, this linear set is an ideal choice for users seeking a reliable and precise linear motion solution without the need for external seals, providing efficient operation in a wide array of applications where torsional resistance and precision movement 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-R109955088-Linear set (aluminum), DRT2-50-WV-2000, without seal
