Oil expansion unit
The oil expansion unit increases the expansion space for the
lubricant. For certain types of construction and at high operating
temperatures, this avoids that lubricant escapes.
The oil expansion unit is supplied as a mounting kit, and can
be mounted onto the geared motor vertically or at an angle.
