There is so much to consider beyond the cost of a single
bearing. In this month's newsletter, we give you details of what
affects your true costs and how you can prolong the life of your
Many believe a low Unit Price
outweighs the benefit of considering the actual Cost of
Ownership. It is certainly easier to just buy low but when you
carefully consider all of the factors impacting the cost of a product,
a low unit price can turn out to be expensive.
Let's consider what factors are
& carrying costs - The cost incurred to carry product on
your shelf. Space, risk of loss, expiration of lubrication and cycle
counting are all costs to be carefully considered. Let National
eliminate all of these requirements by stocking the bearings for you.
Lead-times - Cost of waiting for
the product to be delivered when your current manufacturing lead
times vary from 20 weeks to 42 week. This is an ever changing target and
a consistent issue affecting actual cost. National has the ability to
eliminate lead-time by working closely with your production demands
and stocking the product in support of your actual needs.
Flexibility - The ability to pull-in
or push-out product as necessary to meet demand. In most cases
manufacturers cannot accommodate a schedule change. National offers the
ability to adjust your scheduled product as necessary to match your
Minimum order quantity -
Manufacturers require minimum order quantities. Some require 50 or 100
piece purchases. What is the cost of unnecessary extra product? In
many cases, National will forego minimum manufacturing requirements if
consistent future demand exists for the product.
Quality - Cost of poor quality. Make
the wrong vendor choice and the costs will be significant. National's
vast experience eliminates the selection of questionable vendors with
historically poor quality performance.
Delivery performance - Cost of late
delivery. This can be huge! National works closely with your production
schedule to ensure products are delivered when required. Our goal is
100% on time delivery!
Vendor Management - Cost of managing
multiple vendors. This is a time consuming process for most customers.
National eliminates the need to contact and manage numerous
suppliers. At National this is our role. We manage all vendors and
become your single point of contact for bearings.
Next time you are about to make a purchase based on a
low unit price, remember National Precision Bearing will deliver the
product with a far lower cost of ownership, all things considered. If

You wouldn't try
to replace a Corvette's wheel using a pair of vice grips. Why would
you use a mallet and chisel to remove and install a bearing in an
The use of makeshift bearing
installation tools and methods can result in several expensive
unintended consequences. At its worst, the misapplication of force can
result in significant damage to both the bearing and the housing. At
best, parts are subjected to unnecessary stresses that could
potentially shorten their serviceable life requiring more frequent
maintenance cycles and increased potential for unexpected failure.
Fortunately, these risks are easily avoidable with the use of
appropriate staking, swaging, cutting tools and proof load testers.
Designed for easily repeatable bearing installation and removal, these
tools are available in forms suitable for shop environments or more
portable on-site repair applications.
Most commonly used for installation of
bearings with V-grooves, swagers come in a variety of forms.
Tri-Roller tools evenly push the bearing material over the housing by
combining a rotating action and downward pressure to ensure an even
swage. An animation is available on our website to illustrate this
device in action. Click here to view the Swaging animation. Anvil swagers in
combination with an arbor press may be used to swage both sides of a
bearing at once. Other custom and common swagers are also available
for various applications, including segment stakers for housing over
bearing and sleeve bearings.
Equally important as proper
installation, is the correct removal of the bearing. Cutting tools are
designed to remove a specific bearing with minimum damage to the
housing assembly, saving the added expense of reworking the housing.
Just as a lug and torque wrench on a
wheel, having the right tool for installing and removing bearings,
results in better efficiency and quality with every use. With a
selection of in stock or custom built solutions, National Precision
Bearing can help select and tailor a product for you.
