The Bosch Rexroth LINEAR-SET LSSDR1T-20-WV-900 (R109722085) is a highly precise and robust linear motion set designed for various applications requiring smooth and accurate linear movement. This product features a precision steel shaft with a diameter of 20 mm and a standard length of 900 mm, which includes one ball guide groove for enhanced guidance. The set comes with two torque-resistant linear bushings configured in tandem to provide exceptional stability against cocking loads. The linear bushings are housed in a standard steel precision tandem housing, ensuring high rigidity and alignment. The bearing plates are made from hardened steel and are pre-set to zero clearance by the manufacturer, which guarantees minimal play and maximum accuracy straight out of the box. Despite being without external seals, this product is engineered to offer reliable performance in various conditions within the permissible ambient temperature range specified by the manufacturer. This LINEAR-SET is part of the Series Torque Size E, denoting its capacity to handle dynamic torsional moment loads efficiently. It has been rated with both dynamic and static load capacities, indicating its ability to sustain forces during motion as well as at rest. The maximum permissible linear speed (vmax) and acceleration (amax) parameters define its operational capabilities under different scenarios. With its considerable mass, this product is designed for applications where weight and inertia are factors in the design consideration. Overall, the Bosch Rexroth LINEAR-SET LSSDR1T-20-WV-900 is an exemplary solution for those seeking high-quality linear motion components that provide durability, precision, and reliable performance under demanding conditions.

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-R109722085-Linear set (steel), DRT1-20-WV-900, without seal
