2. Remote bar seals reduce the amount of dirt exposed to the bar packings and assures straight alignment into the seals.

3. Steel main carrier with replaceable thrust plates for less maintenance costs.

4. Heavy duty pivot base and main frame provide long machine life without breaking or bending.

5. More options and custom configurations available than the competition.
