1 Supreme load capacity and accuracy
FYH Ball Bearing Units feature an internal structure identical to single row deep roove ball bearings and
bear significant radial load, as well as a great deal of
axial load in both directions. The hardened steel balls
exhibit a high degree of “roundness” and the races are
highly polished to accommodate a smoother ride at a
wide range of speeds.
2 Rational self-aligning mechanism and optimal fit
FYH Ball Bearing Units have the pecial ability to selfalign
inside the housing because of the spherical shape
of the outer diameter of the bearing insert and the concave
shape of the inner diameter of the ousing into
which it fits. This design allows the bearing unit to selfadjust
for shaft deviation and thereby eliminate abnormal
bearing load. Therefore, the original rated life of the
bearing can be guaranteed.
Since the spherical outside surface of the bearing is
precision ground and the spherical bore of the housing is
machined by a boring machine with great accuracy,
optimal fitting of the bearing and the housing can be
obtained, as well as superior aligning performance.
The allowable aligning angle of standard ball bearing
units is 3º, while units with covers is 1º.
3 Superior sealing performance
FYH Ball Bearing Units efficiently prevent grease from
leaking out of the interior of the bearing, and perform
extremely well at keeping contaminates, such as dust
and water, from entering. This is achieved by installing
the seal to the outer ring of the bearing and installing the
slinger to the inner ring of the bearing.
The seal is made of synthetic rubber with supreme oil
proof characteristics, and the lip of the seal contacts with
the inner ring of the bearing with optimal tension.
When operating in moist or dusty environments, the
triple lip seal unit (suffix code : L3) or a covered unit
(accessory code : C, CD, FC, FD) is recommended.
The triple lip seal unit or unit with cover helps prevent
ingress of water and dust from the outside, and extends
the rated life of the bearing.

4 Simple lubrication
FYH Ball Bearing Units are tapped to accept a grease
nipple which is also supplied with every mounted unit.
Bearings are pre-lubricated at the factory and do not
require additional grease upon installation. When operating
in excessively moist, dusty, or hot environments it is
recommended that grease be supplied at regular intervals.
If appropriately maintained, the rated life of the
bearing can be extended.
The grease nipples that are supplied with FYH
mounted units include 1/4-28 for smaller units and 1/8 PT
for larger units. Additional styles are available upon
request.
5 Highly rigid and rugged cast iron housings
FYH Ball Bearing Units housings are designed so that
they are optimized for reduction of deformation due to
centralization of stress and load. Only the best material is
selected to be cast by a highly advanced technique or
press working technique, depending on the housing.
Since any abnormal load on the bearing is eliminated
by the housing, the life of the bearing can be extended. A
special baked on coating helps resist corrosion and
protect the surface of the housing for an extended period
of time.
6 Simple installation and handling
FYH Ball Bearing Units interchange with many different
models and can be bolted to machinery without any
modification. The exact amount of clearance is allowed
between the bore and the shaft to allow a perfect fit.
Therefore, FYH Ball Bearing Units do not require any
additional lubrication or seal installation. As a result,
handling and downtime can be drastically reduced.
Three different locking mechanisms are available :
(1) set screw
(2) eccentric locking collar
(3) tapered adapter
Mounting the bearing to the shaft can be executed
easily and securely by adopting any of these methods.
