The Bosch Rexroth LINEAR-SET LSADR2T-30-WV-2000 (R109953088) is a high-precision linear motion component designed for applications requiring smooth, accurate, and torqueresistant linear movement. This linear set features a lightweight precision tandem housing made from aluminum and includes a precision steel shaft with two ball guide grooves. The shaft diameter 'd' is included in the standard length as per the provided table. It comes without seals, indicating that it's intended for use in environments where additional sealing against contaminants is not necessary. The LSADR2T-30-WV-2000 model boasts two torqueresistant linear bushings and torque-transmitting, hardened steel bearing plates that are set to zero clearance by the manufacturer to ensure minimal play and precise movement. These features provide stability against cocking loads, which is crucial for maintaining accuracy in dynamic applications. The unit can be externally sealed and is relubricatable, allowing for easy maintenance and extended service life. This linear set is part of the Series Torque Productgroup ID and comes in Size E. It has been engineered with a dynamic load capacity 'C', ensuring it can handle loads effectively when both linear bushings are under equal pressure. The static load rating 'C' indicates its capacity to withstand stationary or slowly moving loads. Additionally, the dynamic torsional moment load capacity 'Mt' specifies its ability to resist twisting forces during operation. With a permissible ambient temperature range from minimum to maximum degrees Celsius (°C), it can operate effectively within various environmental conditions. The LSADR2T-30-WV-2000 has a maximum permissible linear speed 'vmax', which defines its top operating speed limit, while its mass 'm' kg/m provides information on its weight per unit length. Designed as a Tandem format of linear bushings (Format T), this model ensures reliable performance in applications where dual-bushing systems are required or preferred for enhanced load distribution and stability. Its capabilities make it an ideal choice for sophisticated mechanical systems requiring precise guidance and support under torsional stress.

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 .

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.
