The Bosch Rexroth LINEAR-SET LSFDR2-25-WV-900 (R072352585) is a meticulously engineered linear motion component designed for precision and durability. This product is part of the LINEAR-SET series, which features a robust linear bushing and shaft system. The set includes a steel flanged sleeve with a standard steel construction, providing a compact and torque-resistant solution for linear motion applications. The linear set is equipped with ball guide grooves that are specifically designed to accommodate shaft diameters of varying sizes, ensuring smooth and accurate movement. With its torquetransmitting, hardened steel bearing plates pre-set to zero clearance by the manufacturer, this product offers outstanding stability and precision right out of the box. It is designed to withstand cocking loads effectively, making it suitable for applications where two Linear Sets may be installed in parallel as detailed in the installation section. The LSFDR2-25-WV-900 model does not come with external seals, which suggests it is intended for use in environments where additional sealing against contaminants is not required. It also features relubrication capabilities, allowing for maintenance and extended service life. This particular model has a dynamic load capacity C that represents minimal values due to variable loading directions. It can handle maximum accelerations (amax), operate within a permissible ambient temperature range of -20°C to 80°C, and achieve maximum permissible linear speeds (vmax). The static load rating C0 and dynamic torsional moment load capacity Mt are indicative of the product's strength against static and rotational forces. The unit's mass is 0.7 kg/m, making it relatively lightweight yet capable of supporting significant loads. Overall, the Bosch Rexroth LINEAR-SET LSFDR2-25-WV-900 is an efficient solution for various linear motion requirements that demand high precision and reliability without the need for additional sealing protection.

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. technical illustration-R072352585-Linear set (steel), DR2-25-WV-900, without seal
