YOUR WARRANTY LEAN?
Webster defines warranty as
“THE SELLER’S ASSURANCE TO THE PURCHASER THAT THE GOODS OR PROPERTY IS OR
SHALL BE AS REPRESENTED AND, IF NOT, WILL BE REPLACED OR REPAIRED.”
This assurance becomes questionable when warranties exclude a high
percentage of the major wear items on the conveyor.
Most customers are willing to incur a slightly higher initial cost for
a unit that would function for a greatly extended time period with minimal
maintenance over one that also requires part replacement during the same time
period. This is because
replacement down time costs can exceed many times the cost of the entire
Modern Low Profile Conveyors
have two rotating pulleys supported on anti-friction (rolling) bearings.
With the exception of the belt, these two pulley assemblies are the
ONLY conveyor components subject to major fatigue and wear.
These two pulleys rely on the BEARINGS which are the “Heart” of the
conveyor to provide reliable durability. Any
warranty regardless of its time limit, that excludes bearings, may be of
little value, since there are no other major wear items on the conveyor or
drive which are covered by many warranties.
Self-Aligning, sealed for life
ball bearing units of proper capacity are the number one choice for Low
Profile Conveyor bearings. These
bearings have been known to run on a 24/7 basis for over four years without
any maintenance. This type bearing
is comprised of (3) basic elements-outer race, rolling element, and inner
race, with an ample sealed lubricant. Some
conveyors utilizing “shell type needle bearings” also have these (3) basic
elements with one major difference. The
inner race although an integral part of the bearing system is not part of the
basic bearing element manufactured by the bearing company.
The journals of the drive pulley and tail shaft comprise the inner
race. Damage or fatigue of any
bearing element would likely require replacement of the drive pulley and tail
shaft, unlike the ball bearing which confines damage to just the bearing.
Should any manufacturer using this needle bearing construction exclude
bearings from their warranty, the drive pulley and tail shaft might also be
excluded since they are an integral part of the bearing.
It would be wise to confirm warranty coverage on this type drive pulley
and tail shaft when subjected to bearing failure.
Replacement cost of these items can be rather high
Some manufactures promote their
product as “maintenance free”, and then state in their warranty that the
warranty does not apply if the failure was caused by lack of maintenance or
improper maintenance. This may
cause the customer to incur the replacement cost because they were under a
false impression regarding “maintenance free”.
Applying an hour limit on a warranty can also be miss-leading since a 1
year or 2100 hr. limit would result in only a (2.88 month) warranty if the
unit was operating on a 24/7 basis. In
reality, the length of the warranty is meaningless if most of the items that
might be replaced during the warranty period have been excluded.
Another item which can have a
major effect on warranty cost is the pulley diameter.
Two conveyors with identical bearings and belting, running at the same
belt speed, with (1) having a 1.25” diameter pulley, and the other with a
2” diameter will produce a drastic difference in bearing, and belting
fatigue life. The 2” diameter
unit will provide approximately 60% greater bearing fatigue life due to the
fact it is running at a much lower r.p.m. to produce the same belt speed.
The 2” pulley will also have a longer belt fatigue life because the
belt surface stress on the 1.25” pulley is approximately 56% greater than
that of the 2” pulley.
For those considering the
purchase of a new conveyor, it would be prudent to request a copy of the
warranty with the quotation. Any
items not included in the warranty may indicate an abnormal rate of failure,
especially if some others do not exclude these items.

RE-OCCURRING COST DURING AND AFTER YOUR WARRANTY
Anyone that has incurred
(4) or more of the following common costs during their Conveyor’s warranty
period, may find it prudent to review their overall cost.
Conveyor Technologies Products can eliminate up to ninety-three percent (93%) of
these costs during our warranty period, while decreasing the occurrence of the
remaining percentage. An “AFTER WARRANTY BONUS” provides that up to 78% of
these potential costs would always be eliminated. Our ADVANCED TECHNOLOGY
frees our Customers from the vast majority of this re-occurring cost, and
