According to Rose+Krieger this new generation of RK DuoLine
linear units, which are supplied with a spindle or timing belt will
bring greater flexibility to automation. Thinking about on which
side the motor drive should be positioned is no longer necessary.
Optional coupling and motor adapters can be attached to all four
hollow shaft outputs on the idler unit. Not only does this simplify
positioning, customers can also configure and adjust the axial
motor themselves.
The DuoLine with spindle drive is fitted with a newly developed
spindle support for increased rotational speeds. A vmax of 2 m/s with
stroke lengths of around 5 meter is possible. All DuoLine variants
are magnetically sealed with a steel band increasing the protection
rating to IP40. The enclosed ball rail system also provides an
efficiency rating above 85% on the spindle variant and brings the
no-load torque for the timing belt variant down to 2.5 Nm.
The variants also share common features in terms of the table
installation options. The BLOCAN® profile slots have T-rails with
tapped holes to simplify the attachment of loads and provide the
greatest possible flexibility. The central lubricator on the table,
which supplies grease to the guide system and spindles depending
on the type, reduces l maintenance to a minimum. The DuoLine
generation begins with the 160x110 size corresponding to the
length of the edge on the guide profile in mm. The manufacturer
offers a specific service for selecting the right motor specification.
