Device for coupling a coolant supply to a roller

A device for coupling a coolant supply to a roller, the roller being mounted in a pillow block by means of roller bearings via a roller journal and being able to be supplied with a coolant via an axial roller borehole guided through the roller journal, having

• a sealing unit, which can be fixed to the roller journal to couple it to the roller borehole in a pressure-tight manner;
• and
• a pillow block cover, which can be fixed to the pillow block in order to cover the roller bore and which has at least one coolant duct connectable to the coolant supply;
• wherein an insert, which supports the sealing unit in the fitted state, is insertable into the pillow block cover;
• wherein said insert, in order to couple the coolant duct via the sealing unit in a pressure-tight manner to the roller bore, has at least one coolant duct which, in the fitted state, is coupled to the coolant duct in the pillow block cover and to the sealing unit;
• and
• wherein a connecting pipe for connection to a pillow-block footprint, which is coupled to at least one of a coolant removal means and a coolant supply means, is insertable into the at least one coolant duct of the pillow block cover in such a manner that the connecting pipe is completely contained by the pillow block cover.

• a sealing unit, which can be fixed to the roller journal to couple it to the roller borehole in a pressure-tight manner;
• and
• a pillow block cover, which is attached to the pillow block by means of a fastening collar in order to cover the roller bore and which has at least one coolant duct connectable to the coolant supply;
• wherein a plug-in receptacle for receiving a plug-in pipe wherein a plug-in receptacle for receiving a plug-in pipe for connection to at least one of a cooling water supply and a cooling water removal, which is coupled to at least one of a coolant removal means and a coolant supply means, is insertable into the at least one coolant duct of the pillow block cover (9);
• wherein an insert, which supports the sealing unit in the fitted state, is insertable into the pillow block cover;
• and
• wherein said insert, in order to couple the coolant duct via the sealing unit in a pressure-tight manner to the roller bore, has at least one coolant duct which, in the fitted state, is coupled to the coolant duct in the pillow block cover and to the sealing unit.
