Case Study - Dodge Bearing
Dodge Bearing Upgrade Provides Power Saving.
Author - Neil Philp Area Business Development Manager CBC Bearings and Power Transmission
Bearings and Power Transmission have supplied bearing plummer block housing
units to Australian industry for over 50 years. Recent technological
developments from our supplier Dodge Baldor has lead to the development of
Dodge Bearing Plummer Blocks, ISN series. This new design features a patented
locking method that reduces fitting time, eliminates the need for special
tooling and excludes contaminates.
engaged to put forward potential upgrades for a problem kiln fan application
for a customer in the timber industry.
a major issue, as the ongoing need to adjust the Toroidal Roller Bearings off
set of the inner to outer ring to allow for thermal shaft expansion requires
time-consuming attention to detail. This problem is accentuated by the fact
that varying temperature and environment conditions in this area of the plant
affect the stability of the mounting and surrounding structure. Confined space
issues added further difficulty. With the current arrangement this ongoing
maintenance was necessary to prevent potential premature failure of the
bearing. The Dodge Bearing (ISN series) is specifically designed with a
patented locking method to reduce these maintenance issues.
The Proposed CBC Solution
Engineering team put forward a design that utilised 1 only Dodge Bearing, ISN
Plummer Block unit. For further

proposed by CBC involved replacing the two Plummer Blocks with one Dodge
Bearing ISN unit simplifying maintenance and reducing frictional drag resulting
in less power drawn from the motor. The Dodge bearing is also a one piece
design that does not require disassembly for installation, preventing
contamination ingress during installation.
design involved a Falk Lifelign® Gear Coupling and spacer assembly that
provided the required axial float, eliminating stress to any of the drive
customer’s maintenance team noted the simplicity of installation of the Dodge
bearing and the associated time and cost saving. A trial period of the
arrangement was independently monitored and the upgrade has exceeded all
previous performance levels.
comparisons analysed, compiled, and supplied by the customer showed higher
product costs were more than offset by lower labour costs for replacement. This
is shown in the table below.

improvements achieved will be of great ongoing benefit to the timber mill,
reducing power costs, improving production productivity, and increasing
maintenance staff time benefit. The environment will also benefit via reduced
product range offers our customer significant opportunities to reduce, not only
increasingly costly power bills, but also greenhouse gas emissions penalties.
