The Bosch Rexroth LINEAR-SET LSADR1T-20-WV-900 (R109922085) is a high-precision, lightweight linear motion system designed to cater to demanding applications that require smooth and accurate linear movement. This product features a robust aluminum tandem housing, which is both lightweight and torqueresistant, ensuring stability against cocking loads. The precision steel shaft comes with one ball guide groove, enhancing the system's guidance capabilities. Equipped with two torqueresistant linear bushings, this LINEAR-SET is designed for transmitting torque while maintaining zero clearance due to the hardened steel bearing plates set ex works. The absence of external seals in this model indicates that it is intended for use in environments where additional sealing against contaminants is not necessary, making it suitable for clean or controlled settings. The product boasts an impressive dynamic load capacity and static load rating, ensuring reliable performance under both dynamic and static conditions. It has been engineered to handle maximum acceleration and permissible ambient temperatures ranging from -20°C to 80°C without compromising its efficiency or lifespan. The outer diameter D and maximum permissible linear speed vmax are specified to match the requirements of various applications. With a significant dynamic torsional moment load capacity Mt, the LINEAR-SET LSADR1T-20-WV-900 can resist twisting forces effectively. Additionally, it offers the convenience of being relubricatable, which simplifies maintenance procedures and extends the product's service life. This linear set belongs to Productgroup ID Tandem (T), indicating its format as part of a series designed for synchronized motion involving multiple components. Its size specifications such as E, H, L along with weight details are meticulously crafted to ensure optimal performance. Overall, this Bosch Rexroth product is a sophisticated solution for applications requiring precise linear motion control with high load capacities and resistance to torsional forces.

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-R109922085-Linear set (aluminum), DR1-20-WV-900, without seal
