Bearings of the TQI configuration

Bearings of the TQI design have two paired rows of rollers arranged back-to-back (Their use is limited, being primarily where high stiffness is required and considerable tilting moments have to be accommodated. The bearings are generally mounted with an interference fit on the roll necks and therefore often have a tapered bore. The bearings are also used for the vertical rolls of universal mills; in this case the outer rings are mounted with an interference fit in the chocks and the inner rings have a loose fit on their seat.

Because of their limited application, only a few sizes and designs are produced by SUP BEARING. The designs described in the following and shown in the product tables belong to the SUP BEARING standard manufacturing programme.
