The Bosch Rexroth LINEAR-SET LSHDR1T-12-WV-900 (R072221285) is a high-quality linear motion set designed for precise and smooth linear movements in various applications. This product features a robust steel construction with two torque-resistant compact linear bushings and a ball guide groove suitable for diameter shafts, enhancing its stability against cocking loads. The set comes with a standard-length shaft included, ensuring compatibility and ease of installation. Designed for efficiency, the LINEAR-SET LSHDR1T-12-WV-900 operates without seals, which simplifies maintenance while still providing reliable performance. It is equipped with torquetransmitting hardened steel bearing plates that are set to zero clearance ex works, ensuring minimal play and high precision in operation. The product is also relubricatable, allowing for extended service life through proper maintenance. With a dynamic load capacity (C) that ensures the system can handle the required forces during operation and a static load rating (C0), this linear set is engineered to withstand both dynamic and static stresses. Additionally, it has been optimized to work within a permissible ambient temperature range of -20°C to +80°C, making it suitable for various working environments. The LINEAR-SET LSHDR1T-12-WV-900 boasts an impressive maximum permissible linear speed (vmax) and can accommodate maximum acceleration (amax) demands without compromising performance. Its design also includes keyways for effective torque transmission. Weighing at 2.7 kg/m, this linear guide type provides an ideal balance between strength and weight, contributing to its dynamic torsional moment load capacity (Mt). Overall, the Bosch Rexroth LINEAR-SET LSHDR1T-12-WV-900 offers reliability and precision for applications requiring linear motion control with its well-engineered features and durable construction.

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

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.
