“Shaft size” is the measurement of shaft for your application. It can also be similar to the measurement of the “Bore” or “Inside Diameter” of your bearing. A slightly loose shaft fit is desirable for most applications.
For linkages and rod ends, shafts are not typically used but it refers to the measurement of the bore ID whether you are using a bolt or screw through the inside diameter of your rod end. See image below.
Bearings with grease fittings are NOT factory lubricated. Grease should be applied with a pressure gun at the time of installation, filling the ball unit and bearing until grease appears at the shaft surface.
Grease for a lubrication is recommended for applications with lower speeds and loads. Because the grease restricts contaminants from entering it is preferred for dusty and dirty applications.
PLASTIC E LUBE
Gulf Plastic Petroleum “E” feeds slowly through the bushing by capillary action, replacing dissipated lubricant. Factory-lubricated ball units may be closed balls or equipped with removable plugs for relubrication.
SAE 30 NON-DETERGENT OIL
FOR BEARING BALL WITH BUSHING
Triangle Steel Bearing Ball Units have large oil retaining felts for substantial lubricant capacity. Once the bearing is in use and the ball and felt saturated with oil, long bearing life may be expected under proper operating conditions. The standard oil supplied is a good grade of industrial mineral oil, NON-DETERGENT, SAE 30 viscosity. Bearing use at elevated or very low temperatures may require oil of different viscosity. Triangle recommends relubrication of bearings at the time of installation even though a full supply of oil is provided at the factory. Conditions encountered during shipping and storage may cause some oil loss.
FOR SINTERED BEARINGS
Triangle’s sintered bearings are oil impregnated with SAE30-Non-Detergent oil. These bearings are porous which allows for the bearing to be constantly re-lubricated while being used.
BEARINGS WITH SPECIAL LUBRICANT
Triangle is not limited to the lubrication methods described above. If you require a special lubricant, please contact us. We will be happy to discuss that requirement with you.
