Drawn cup needle roller bearings generally do not have an inner ring
Drawn cup needle roller bearings generally do not have an inner ring, and the
inner ring can be used when the journal cannot be hardened and ground. Because
of the special structure, the drawn cup needle roller bearing and the bearing
box must be installed in a dry and cooperative way.
Drawn cup needle roller
bearings are needle roller bearings with thin stamped and formed outer rings.
Minimal and economical.. Based on this, it can be used for the bearing equipment
with compact structure, low price and the inner hole of the bearing box cannot
be used as the raceway of the needle roller cage assembly .
If the axial
positioning functions such as the shoulder and stop ring can be omitted, the
inner hole of the bearing box can be manufactured. Compared with general needle
roller bearings, in addition to the difference in appearance and structure, more
of them are still in terms of function.
Under normal circumstances, the hardened
steel outer ring of the drawn cup needle roller bearing cannot be separated from
the needle roller cage assembly, and the free space for storing the smoothing
agent can extend the smoothing distance; the outer ring of the bearing is also
designed with smooth oil holes, according to According to user requirements, all
single row drawn cup needle roller bearings with a shaft diameter greater than
or equal to 7mm can be equipped with outer rings with smooth oil holes.
What are
the characteristics of drawn cup needle roller bearings? Because of the low
cross-section height of the drawn cup needle roller bearing, it can accept a
higher load. It is observed that the drawn cup needle roller bearings installed
on the shaft end have two side open type and single side closed type, which are
satisfactory for different working conditions, during which the base end surface
of the closed drawn cup can Mechanical
roller bearing accept little axial guiding force
