The Bosch Rexroth LINEAR-SET LSHDR2-20-WV-2000 (R072152088) is a high-quality linear motion set designed for precise and efficient linear movement applications. This product features a precision steel tandem housing and a precision steel shaft with two ball guide grooves, which are suitable for shaft diameters of 20 mm and higher. The inclusion of a keyway enables effective torque transmission, making this linear set ideal for applications requiring precise motion control and high load capacities. The LINEAR-SET LSHDR2-20-WV-2000 is designed with torquetransmitting, hardened steel bearing plates that are set to zero clearance ex works, ensuring stability against cocking loads. It does not come with external seals but is relubricatable, which contributes to its longevity and maintenance ease. The product has been engineered for resistance to torsional loads, further enhancing its robustness in demanding operational conditions. With a static load rating (C0) and dynamic load capacity (C), this linear set can handle minimal values as the direction of loading may not always be clearly defined. It operates efficiently within a permissible ambient temperature range of -30°C to +80°C, making it versatile for various environmental conditions. Additionally, it can withstand maximum accelerations (amax) and achieve high linear speeds (vmax) without compromising performance. The Bosch Rexroth LINEAR-SET LSHDR2-20-WV-2000 weighs approximately 1.5 kg/m and offers a dynamic torsional moment load capacity (Mt), tailored for applications that demand high rigidity and accuracy. Its sleeve design format facilitates ease of installation in various configurations while providing reliable guidance for the supported shaft. Overall, the Bosch Rexroth LINEAR-SET LSHDR2-20-WV-2000 is an essential component for designers and engineers looking to implement sophisticated linear motion solutions in their machinery or automation systems.

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.

Installation Linear sets with torque-resistant compact linear bushings

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.
