The term Superclad refers to a Vesconite bearing that is built up on the outside surface with a reinforcing system, to achieve the required external dimension.

For fitting, the Vesconite bearings were first cooled with liquid nitrogen to reduce the diameters, and were then slid easily into the housing.

Advantages of Vesconite Superclad:
Can be built up to any outside diameter to avoid the time lost in producing another bearing.

Advantages of freeze fitting:
Freeze fitting is the easiest way to install Vesconite bearings.
