The Bosch Rexroth PRECISION MODULE PSK-050-NN-1 (R030519868) is a high-performance, ready-to-install linear system that offers precision movement for a variety of applications. This module is designed with compact dimensions and features a ball screw with zero-backlash cylindrical single nut, ensuring smooth motion and high guiding accuracy of up to 0.005 mm. The system can achieve repeatability of up to 0.01 mm and positioning accuracy of up to 0.05 mm, making it suitable for tasks requiring exacting precision. The structural design of the PSK-050-NN-1 includes an option without a cover or with a sheet cover or sealing strip, providing flexibility in protecting the internal components based on the user's environmental needs. The frame incorporates an integrated guideway geometry and reference edge for quick installation and easy alignment of the axes. Motor attachments can be customized through various kits according to customer specifications, including maintenance-free servo motors with optional brakes and attached feedback systems. This module comes in different configurations with either one or two steel carriages available in standard or long lengths. The floating bearing end block, fixed bearing end block, aluminum mounting duct for sensors, and various connection accessories complement the system's robust design. Adjustable sensors can be placed over the entire travel range for precise control. Additional components that enhance the functionality of the PSK-050-NN-1 include switches for operational control, mounting ducts for organization, and switch tabs for easy integration into existing systems. Overall, this precision module by Bosch Rexroth is engineered to provide reliable performance in demanding applications where accuracy is paramount.

Rexroth precision modules are precise, ready-to-install linear systems with high performance features in compact dimensions. Rexroth offers an attractive price/performance ratio and short delivery times.

Mounting

 

Do not secure or support the precision module at the end blocks! The frame is the load-bearing part!

 

The Precision Modules are mounted with screws via through-holes in the frame.

When mounting the Precision Modules, please note the maximum tightening torques listed in the table.

The reference edge on the frame makes it easier to align the Precision Module.

Remove the cover plate, if present, before mounting. For connection dimensions, see the relevant dimension drawings.

Fastening with screws in the frame

The reference edge on the frame makes it easier to align the precision module.

Suitable for the cover variants:

without cover with sheet cover (remove the cover strip before attaching). The connection dimensions can be found on the respective dimension drawing.

Mounting with clamping fixtures PSK-050 to PSK-090

The reference edge cannot be used in the clamping fixture area.

Suitable for all cover variants.

Notes for mounting

The switch mounting is only permitted on one side of the precision module (left or right).

A fastening duct is required for the attaching of the switches. The switches are pushed into the slot on the fastening duct and secured with set screws.

Switch

 

The switches for the PSK precision modules are magnetic field sensors with fixed potted cable.
