The Bosch Rexroth LINEAR-SET LSFDR2-40-WV-900 (R072354085) is a high-quality linear motion set designed for precision applications. This product features a steel flanged sleeve and a compact, torque-resistant linear bushing that is equipped with ball guide grooves to facilitate smooth movement. It is specifically constructed to handle shaft diameters of 40mm, with the inclusion of a standard length shaft as per the table provided by Bosch Rexroth. The LINEAR-SET LSFDR2-40-WV-900 is notable for its ability to transmit torque effectively, thanks to its hardened steel bearing plates which are set to zero clearance ex works. This ensures precision alignment and minimizes play in the system. The set is designed without external seals, which simplifies its structure while still providing stability against cocking loads. For applications requiring additional stability, instructions for installing two Linear Sets are available in the installation section of the product documentation. This product can be used in environments with temperatures ranging from -10°C to +100°C and can handle a maximum acceleration (amax) and maximum permissible linear speed (vmax), details of which are specified by the manufacturer. The dynamic load capacity C and static load rating C0 indicate minimal values due to variable loading directions, ensuring robust performance under different conditions. Moreover, the LINEAR-SET LSFDR2-40-WV-900 has relubrication capabilities for maintenance ease and longevity of service life. The dynamic torsional moment load capacity (Mt) further underscores its suitability for demanding applications that require precise rotational force control. Weighing at .9 kg/m, this linear motion set strikes an optimal balance between strength and weight, making it suitable for various industrial uses where reliable linear guidance is necessary. The product belongs to a series designed for versatility across numerous applications without compromising on performance or quality.

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.
