Part Three: Lubrication
Bearing and linear bearings systems have advanced over the years but they must be maintained on a regu-
lar basis if you expect them to last and perform effi ciently. TuffStuff uses only the highest quality bearings
and linear motion components that are virtually trouble-free but requires the regular preventive maintenance
to insure long-lasting performance.
1. Bronze and nylon bushings, we recommend on a monthly basis to spray a tefl on-base lubricant
(silicone-free) directly onto the shaft as it passes through these bushings. Spray a small amount
onto the shaft and rotate it through its complete movement and wipe off any excess.
2. Weight stack guide rods and bushings, again use tefl on spray lubricant and this time spray onto
a rag and wipe the guide rods down with this rag on a weekly basis. Do not use WD-40 or other
lubricants as they attract dirt and will crate a mess between the weight plates and bushings.
3. Sealed bearings pivot points, as the name implies are protected from the outside environment
and require no lubrication. During the machine wipe down, wipe the external bearing surfaces
with the damp rag and dried to prevent the build up of dust and sweat.
4. Linear bearing systems are precision, high load components that require regular maintenance.
Dirt and corrosion are the major culprits in linear bearing failure. The hardened shafts must be
wiped down weekly and lubricated with a light layer of tefl on grease. We recommend a tefl on-
base (silicone-free) gel/grease for this purpose. Lack of care and maintenance will result in cor-
rosion of the linear shaft causing the bearings to clogged and jammed
.
If you religiously perform the maintenance procedures, you will increase the life of the machine and ulti-
mately lower your maintenance costs with fewer replaced components and downtime.
Any doubts, equipment with mechanical problems should be placed “Out-of-Service” until all problems are
corrected. If replacement parts are required or maintenance questions, please contact:
