For fitting, the Vesconite bearings were first cooled with liquid nitrogen to reduce the diameters, and were then slid easily into the housing. See procedure for using nitrogen
| Advantages
of Vesconite Superclad: Can be built up to any outside diameter to avoid the time lost in producing another bearing.
