The Bosch Rexroth LINEAR-SET LSADR1-12-WV-400 (R109821280) is a comprehensive linear motion set designed to offer precision and high load-bearing capabilities in various applications. This set includes an aluminum, torque-resistant lightweight precision tandem housing, paired with a precision steel shaft featuring one ball guide groove. The shaft diameter 'd' is included as standard length according to the provided table. The LSADR1-12-WV-400 linear set is characterized by its absence of external seals, making it suitable for environments where contamination is not a significant concern. It comes in a standard version that emphasizes ease of use and maintenance with features such as relubrication capability for extended service life. Engineered for stability against cocking loads, the linear set integrates torquetransmitting, hardened steel bearing plates that are pre-set to zero clearance from the factory, ensuring optimal performance right out of the box. The dynamic load capacity 'C' and static load rating 'C0' are minimal values reflective of diverse loading directions that may be encountered during operation. The product boasts a dynamic torsional moment load capacity 'Mt', which underscores its ability to handle varying degrees of torque applied during use. The maximum permissible linear speed 'vmax' and mass 'm kg/m' are specified for precise engineering requirements. Operating within a permissible ambient temperature range from minimum to maximum degrees Celsius, this linear set can adapt to different working conditions. Bosch Rexroth's LINEAR-SET LSADR1-12-WV-400 also features an impressive max acceleration 'amax', ensuring rapid motion capabilities while maintaining accuracy and reliability. This particular model is part of the Series Torque Productgroup ID Size E, which indicates its standardized dimensions and compatibility with other components in the same category.

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-R109821280-Linear set (aluminum), DR1-12-WV-400, without seal
