The Bosch Rexroth LINEAR-SET LSADR2-20-WV-2000 (R109852088) is a high-quality linear motion system designed for applications requiring precise and smooth movement. This linear set is characterized by its lightweight aluminum tandem housing and precision steel shaft with two ball guide grooves, making it resistant to torque and providing excellent stability against cocking loads. The shaft diameter 'd' is included in the standard length as per the provided table, ensuring compatibility with various installation requirements. The LSADR2-20-WV-2000 set comes without an external seal, which simplifies maintenance while still being relubricatable to ensure long-term performance. The absence of a seal also contributes to the system's lightweight design, making it suitable for applications where weight is a critical factor. The hardened steel bearing plates are pre-set to zero clearance ex works, offering immediate high precision upon installation. With a dynamic load capacity 'C' that represents minimal values due to varying load directions, this linear set can handle significant dynamic loads. It also boasts a substantial static load rating 'C' and dynamic torsional moment load capacity 'Mt', ensuring durability under various operating conditions. The permissible ambient temperature range extends from minimum to maximum degrees Celsius, accommodating different working environments. This Bosch Rexroth linear guide type includes a linear bushing and shaft system that can reach a maximum permissible linear speed 'vmax', while the mass 'm kg/m' indicates the weight per meter of the system. Designed for ease of use, this product is part of the Torque Productgroup ID and comes in Size E with additional specifications provided regarding size H, outer diameter D, maximum acceleration 'amax', and more. In summary, the Bosch Rexroth LINEAR-SET LSADR2-20-WV-2000 offers robust construction, precise movement capabilities, and versatile application potential for users seeking reliable linear motion solutions.

1) 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 .

Life expectancy calculation

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-R109852088-Linear set (aluminum), DR2-20-WV-2000, without seal
