FAQ

What is the purpose of the blue coating on the screw threads?

The blue coating is a pre-applied thread-locking adhesive. It prevents the screws from loosening due to vibration, ensuring a secure and long-lasting connection between the rail sections.

Is this kit compatible with other sizes of Rexroth ball rails, such as size 20 or 25?

No, this specific kit, R039120046, is designed exclusively for size 15 ball rails (indicated by ‘X15/Y15’ on the label). Using it with other sizes will result in misalignment and improper function.

Are there specific torque specifications for tightening the screws in this kit?

Yes, Bosch Rexroth provides specific torque values for all their fasteners to ensure proper clamping force without damaging the components. It is crucial to consult the official Rexroth assembly instructions for the size 15 ball rail system to find the correct torque specification for these connecting screws.
