moisture and contamination working its way past the
protective seals. Bearings that are greased will 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 periodic
inspections of bearing condition and seal integrity should
be conducted to avoid downtime. These bearings should
be inspected seasonally and replaced if 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 warranty.
Note: Bearing life can be negatively affected by improper
wash down procedures. Do not wash down the unit when it
is still hot and avoid directing high-pressure or high volume
spray at the bearings.
