Checking the Sealed
Bearings
Bearings rarely fail from defects in materials or
workmanship. The most common reason for failure is
moisture and contamination working its way past the
protective seals. Bearings that are greased rely upon
regular maintenance to purge harmful debris from the
bearing area. Sealed bearings rely on an initial fill
of special grease and a robust integral seal to keep
contaminants and moisture out of the rolling elements.
The sealed bearings require no lubrication or
short-term maintenance. This minimizes routine
service required and reduces the potential of turf
damage due to grease contamination. These sealed
bearing packages will provide good performance and
life under normal use, but you should periodically
inspect the bearing condition and seal integrity to
avoid downtime. Inspect the bearings seasonally
and replace the them if they are damaged or worn.
Bearings should operate smoothly with no detrimental
characteristics such as high heat, noise, looseness,
or indications of corrosion (rust).
Due to the operating conditions these bearing/seal
packages are subject to (i.e., sand, turf chemicals,
water, impacts, etc.) they are considered normal wear
items. Bearings that fail due to causes other than
defects in materials or workmanship are typically not
covered under the warranty.
Note:
Bearing life can be negatively affected by
improper wash-down procedures. Do not wash down
the machine when it is still hot and avoid directing
high-pressure or high-volume spray at the bearings.
