The Bosch Rexroth LINEAR-SET LSADR1-12-WV-1200 (R109821287) is a high-quality linear motion set designed for precision applications requiring smooth and accurate movement. This linear set is comprised of a lightweight precision tandem housing made from aluminum, which provides a sturdy yet nimble foundation for the system. The included precision steel shaft has a diameter of 12 mm and features one ball guide groove, offering torqueresistant properties that enhance the system's stability and resistance to cocking loads. The LSADR1-12-WV-1200 is equipped with torquetransmitting, hardened steel bearing plates that have been meticulously set to zero clearance by the manufacturer, ensuring optimal performance straight out of the box. This attention to detail in manufacturing translates into reliable operation and longevity of the component. Additionally, this linear set model does not include external seals but remains relubricatable, allowing for easy maintenance and extended service life. With its dynamic load capacity C and static load rating C specifically designed to handle minimal values due to varying loading directions, this linear motion set is capable of accommodating diverse application needs. It also boasts a dynamic torsional moment load capacity Mt, which further attests to its robustness in handling twisting forces during operation. The LINEAR-SET LSADR1-12-WV-1200 operates efficiently within a permissible ambient temperature range from -20°C to +80°C and can withstand maximum accelerations as specified by Bosch Rexroth standards. Its design facilitates maximum permissible linear speeds while maintaining a low mass-to-performance ratio, making it an ideal choice for applications where weight and speed are critical factors. Whether used in single or multi-axis configurations, this linear guide type with its torqueresistant linear bushing ensures precise guidance and reliable performance for various motion control tasks.

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-R109821287-Linear set (aluminum), DR1-12-WV-1200, without seal
