Abstract: A bearing arrangement supporting a sealing bellows around a shaft to permit axial and angular motion includes inner and outer bearing sleeves, and a rolling bearing having an inner race ring fitted around the inner sleeve with one end face engaging a shoulder in the inner sleeve. A sealing device is provided in a space between the inner and outer sleeves. A flexible elongated bellows for enclosing a portion of the shaft is sealingly connected at one end to the outer surface of the outer sleeve and is attachable at its opposite end to a fitting of a machine member from which the shaft projects. The outer sleeve is a sheet metal sleeve provided with an inwardly bent flange portion forming an engagement surface for the opposite side face of the rolling bearing. The bellows is fixedly attachable to the outer surface of the outer sleeve by bonding through vulcanization.

Abstract: A precision spindle unit for low friction performance includes a tubular housing surrounding a shaft, and first and second rolling bearings mounted on the shaft within the housing. The first bearing is axially arrested between the flange of a locking washer fixed to the shaft and a shoulder on the shaft. A second locking washer is fitted to the shaft, and a resilient member is provided between the second locking washer and a side of the inner race ring of the second bearing. The axially inwardly facing side of the outer race ring of the second bearing engages an inwardly projecting shoulder in the housing, with the second bearing being biased between the resilient member and the inwardly projecting shoulder. The locking washers define a slot seal at each axial end of the housing to provide a seal at the outwardly facing sides of the first and second bearings.

Abstract: A fishing reel includes a spool rotatably supported in a bearing arrangement on a spindle unit. The spindle unit is a held-together unit incorporating an elongated spindle and a bearing housing supported on the spindle by at least two spaced apart rolling bearings. Annular end washers on the spindle shield off the interior of the housing from the surrounding environment via a small slot acting as a seal. The housing has at least one exterior radially extending shoulder and the spool has at least one internal projection intended to engage the shoulder of the housing to define the axial position of the spool relative to the bearings while also taking up axial load in one direction. A resilient member between the bearing housing and the spool gives play-free contact between the housing and the spool and gives a pretension of the spindle unit against the shoulder of the housing.
