The Bosch Rexroth LINEAR-SET LSADR1T-20-WV-500 (R109922080) is a high-quality linear motion set designed for precision applications where resistance to torque and stability against cocking loads are essential. This set includes a lightweight precision tandem housing made from aluminum and a precision steel shaft with one ball guide groove, ensuring smooth and accurate linear movement. The shaft diameter 'd' is included in the standard length as per the table provided by Bosch Rexroth. This linear set is equipped with two torque-resistant linear bushings and torquetransmitting, hardened steel bearing plates that have been set to zero clearance ex works, which contribute to the system's high rigidity and load capacity. The dynamic load capacity 'C' specified for this model indicates the minimal values for load capacities when both linear bushings are under equal load. It also features an impressive dynamic torsional moment load capacity 'Mt', which speaks to its ability to handle varying loads and stresses during operation. The LSADR1T-20-WV-500 operates efficiently within a wide range of permissible ambient temperatures, making it versatile for various working environments. The maximum permissible linear speed 'vmax' and the maximum acceleration 'amax' ensure that this linear set can meet the demands of high-speed applications without compromising performance. Furthermore, this model has been designed without external seals but remains relubricatable, which simplifies maintenance while extending the service life of the components. With its specific format of linear bushings (Tandem T), it provides an optimal combination of precision and durability. Overall, the Bosch Rexroth LINEAR-SET LSADR1T-20-WV-500 is an advanced solution for those seeking reliable linear motion with high load capacities, torsional rigidity, and operational reliability in their mechanical systems or machinery setups.

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-R109922080-Linear set (aluminum), DRT1-20-WV-500, without seal
