BEARING INSTALLATION AND MAINTENANCE
NOTE: To prevent premature failure – please ensure greasing instructions below are applied. As well,
tighten bearing set screws, collars, and wheel lugs every four to six months.
ENGINEERING – BALL & ROLLER BEARINGS LUBRICATION
For bearings that are equipped with a hydraulic grease fitting threaded into the housing for ease of
lubrication, the proper amount of lubricant in the bearing is important. Both excessive and inadequate
lubrication may cause failure. The bearings should be re-lubricated while they are rotating (if it is safe to
do so); the grease should be pumped in slowly until a slight bead forms around the seals. The bead in
addition to acting as an indicator of adequate re-lubrication provides additional protection against the
entry of foreign matter and helps flush out contaminates in the bearing.
By the time the slight bead is formed, it will be noticed that the bearing temperature will rise. It is not
uncommon for the temperature to rise as much as 30 degrees Fahrenheit after re-lubrication. If
necessary to re-lubricate while the bearing is idle, refer to the recommended re-lubrication grease chart
tables on the following page for various sizes of the bearings.
LUBRICANT-STANDARD BEARINGS:
All bearing units are pre-lubricated at the factory with a lithium soap grease which is compatible with
multi-purpose grease readily available from local suppliers. The lubricant selected for factory lubrication
uses a highly refined mineral oil with a high viscosity index, thickened with lithium soap to conform to
NLGI grade 2 consistency. A suitable additive package is added to protect the highly polished rolling
contact surfaces from corrosion and oxidation of the lubricant. The lubricant is satisfactory for an
operating temperature range of –30 F to +250 F.
Select standard industrial grade greases that conform to the following specification for optimum bearing
performance:
General Duty Ball & Roller;
58-75 SUS @ 210 F
450-750 SUS @ 100 F
Premium Duty Ball & Roller;
68-75 SUS @ 210 F
600-750 SUS @ 100 F
Heavy Duty Roller Bearing;
82 SUS @ 210 F
886 SUS @ 100 F
NOTE: For heavy loaded roller bearing applications, grease with EP additives are often recommended
for optimum performance.
