The patented Marldon system has two unique features which overcome
the inherent weaknesses in alternative suppliers' designs
- A solid one-piece housing with fixed, load carrying bushings
fitting onto the shaft.
- A driving system independent of the housing.
The combination of these features acts to separate the two functions
of a traverse unit, the functions of load bearing and driving.
Consequently the performance of the Marldon traverse is not affected
by external masses carried upon it as any loads are transmitted
through the housing onto the load carrying bushes and hence onto
the shaft, putting no stress on the internal rolling bearing mechanism.
Consistent even performance is assured. (Competitors' designs
must use the internal bearing mechanism to carry the unit - and
externally imposed loads - leading to increased wear and variable,
Additionally, and very importantly, the Marldon design means that
the unit remains stable longitudinally. (Competing designs
must "float" around the shaft leading to a rocking action
which results in loss of precision and variation in side thrust.)
The Marldon traverse is the only unit with these features.
