CASTER, WHEEL, AND BEARINGS
PREVENTATIVE MAINTENANCE
Simple preventative maintenance for your casters will greatly extend caster and wheel life. The following steps will
help assure that your casters live up to your expectations and application requirements.
COMMON CAUSES FOR POOR PERFORMANCE OR QUICK WEAR DOWN
In many cases, caster and wheel products wear quickly by subjection to abusive or unreasonable demands. The most
important factor in making your caster and wheel products last is choosing the correct caster for your needs.
PERIODICALLY EXAMINE EQUIPMENT
x
Frame and Fasteners
x
Tighten loose bolts and nuts and look for broken welds or deck boards.
x
Look for frame distortion due to overloads or impact loads. A distorted frame can cause premature
wheel failure because of abnormal loads on one or two casters.
x
Lubrication
x
All caster bearings need to be lubricated with a high-quality multi-purpose grease that has good
extreme pressure and anti-wear characteristics, as well as withstands temperature range that fits the
application requirements. Wheel and swivel bearings last longer if lubricated regularly.
x
Normal conditions may warrant lubrication every six months, but once a month may be necessary in
extreme applications, such as corrosive or exceptionally dirty environments
x
Wheels
x
Check for visible points of tread wear. Flat spots may indicate foreign material, such as string, thread,
metal, etc., causing wheels to bind. Thread guards will delay build-up of such materials.
x
Loose casters or frozen wheels may also produce flat spotting.
x
Replace wheel and/or caster to avoid erratic rolling. After inspecting and making corrections, be sure
axle nut is properly tightened.
x
Proper Equipment Usage
x
Overloading or dropping loads (shock loading) on carts, trucks, or bins may cause sudden wheel or
equipment failure.
x
High speeds on rough floors can quickly create severe damage to tread and wheels.
