Ball
Bearings
Ball
bearings are machinery components, which comprise an outer ring,
inner ring, balls, retainers, shields and snap rings. Miniature bearings
and small-sized ball bearings have up to
30mm in external diameter. Essential to high-precision rotary components,
ball bearings
determine rotational accuracy.
Bearing types include Radial Ball Bearings (Deep Groove and Angular
Contact) and Thrust Ball Bearings. Radial bearings are
designed to carry both radial and axial (thrust) loads, while thrust
bearings are designed for pure thrust loads only. Many different
configurations are available for ball bearings.

Miniature
Bearings
- Our
miniature bearings range in sizes from .1181 to 1.000 inch O.D.
(3mm to 26mm), and are available in inch and metric sizes.
Miniature
bearings and instrument bearings are single row bearings.
The construction of these miniature bearings enables them to carry
moderate radial and thrust loads at low operating torque while
providing high performance within a small envelope design. Miniature
bearings and instrument bearings are typically available in both
stainless steel for those applications requiring corrosion resistance
and chrome for maximum fatigue life.
Minebea
manufactures more than 8,500 different types of miniature and small-sized
bearings, most of which have external
diameters
of 22mm or less.

Precision
Bearings and Metric Precision Bearings
NMB's
precision bearings are composed of materials that are subjected
to severe stress reversals of approximately 1000 MPa. For applications
with high pressure compressive stress reversals, an extremely
pure and hard material is required for our precision bearings.
NMB mainly uses high performance carbon chromium steel; or when
good corrosion resistance is required, martensitic stainless
steel in its precision bearings.
Developed
by NMB's parent company, MKJ3 is a high carbon chromium bearing
steel combined with a special heat treating process. This steel
makes our precision bearings have a higher hardness and a more
stable structure than standard chrome bearing steel. This allows
the steel to retain its shape under adverse conditions.

Radial
Bearings
- Standard
inch and metric series radial bearings carry moderate radial and
thrust loads at low operating torque and provide high performance
within
small envelope designs.
Radial
ball bearings are probably the most widely used and most recognized
ball bearing. These radial bearings have one row of balls (referred
to as a single row), which revolves around the ball path. This feature
provides another name for the radial bearings; they are commonly
called deep groove bearings.
NMB radial
bearings are used in aircraft components, such as wing flaps, engine
and wing mounts and hatches, and rod-ends. These
radial bearings are
also used extensively in helicopters, trains and automobiles, functioning
as joints.

Mechanical
Assemblies
NMBs precision mechanical assemblies are bearing mechanical assemblies designed
for a wide range of applications, including high accuracy head positioning
pivot
assemblies, encoder assemblies for robotics, CAD/CAM systems and factory
automation. Many of these mechanical assemblies are found in office automation,
including integral bearings for use in rigid disk drive spindles, and
as part of printers, fax machines and copiers.
NMB produces precision mechanical assemblies for printers facsimile machines,
copiers and telex typewriters. Our engineers can help you design a
quality, cost efficient mechanical assemblies that can be produced
in small or volume production
quantities.
