A bearing alignment tool and method of use is provided for aligning inner
and outer races of a roller bearing of the class wherein the inner and
outer races of the roller bearing are axially displaceable with respect
to each other in order to accommodate thermal growth of a rotating shaft.
A bearing replacement procedure includes: (a) affixing the roller bearing
to the shaft at its inner race; (b) disposing the shaft in a housing; (c)
aligning the inner and outer races of the roller bearing with respect to
each other and the housing in a predetermined spatial relationship by
affixing an alignment tool to the housing, wherein the alignment tool has
(i) an outer aligning surface which engages the outer race of the roller
bearing; and (ii) an inner aligning surface which engages the inner race
of the roller bearing; (d) removing the alignment tool from the housing;
and (e) securing the housing to a fixed position on a support while
maintaining the predetermined spatial relationship established in step
(c). The method and alignment tool are particularly useful for quickly
replacing bearings on an afterdryer of a papermachine where precision
alignment and downtime are significant considerations.
