Why Coupling Grease?
Ample lubrication is vital for satisfactory gear coupling operation. Gear Coupling Grease is especially designed for gear coupling applications to improve coupling lifestyle though dramatically minimizing maintenance time. Its substantial viscosity base oil and tackifier mix to maintain the grease in place and reduce separation and it is actually in full compliance with NSI/AGMA 9001-B97 lubrication recommendations.
Coupling Grease is dark brown in shade and manufactured by using a lithium soap/polymer thickener, which has superior resistance to oil separation when subjected to substantial centrifugal forces typically observed in couplings. Bearing or basic goal greases tend to separate and reduce effectiveness resulting from large centrifugal forces on the many components at substantial rotational speeds. These higher centrifugal forces encountered in couplings separate the base oil in the thickeners. Heavy thickeners, which have no lubrication characteristics, accumulate while in the gear tooth mesh place resulting in premature coupling failure. Gear Coupling Grease is created to hugely resistant to centrifugal separation with the oil and thickener, which makes it possible for the lubricant to be utilised for any fairly extended time period of time.
Among the techniques to the success of Gear Coupling Grease is the variable consistency throughout the doing work cycle with the application. The consistency of our gear coupling grease improvements using the working ailments. Working of the lubricant under real services ailments triggers the grease to turn out to be semi-fluid, functionally solash lubricating the dress in surfaces of your coupling. Because the grease cools, it returns to your original consistency, thereby stopping leakage.
Gear Coupling Grease is obtainable from stock in 14 oz. cartridges, 1 lb. and five lb. cans.
Characteristics
Minimizing of coupling wear
Resistance to water washing
Corrosion and rust safety
Large load carrying capabilities
Extended relubrication frequency
Use at temperatures as much as 325° F
Staying in place underneath substantial speeds
Resistance to centrifugal separation
Reduction in down time & upkeep cost
Gear Coupling Grease has a consistency which overlaps the NLGI grades 0 and one. This grease is specially formulated with a lithium/polymer thickener and fortified with corrosion, oxidation, extreme pressure, and a effective rust inhibitor additive package.

Engineered Shear Pin Form
Shear pin couplings are generally applied to limit transmitted torque to a redetermined load. THis in turn disconnectes the driver and driven shafts if torque exceeds the specified limits. They’re primarily suited to guard tools when jams occur. Elements are re-useable immediately after pins shear. The coupling will retain lubricant for any short time period to permit tools to become shut down.

Replaceable brakewheel and brake disc piloted around the outside diameter of the normal sleeve and/or rigid hub. Provides a decision of applying braking energy to the load or driving motor.
Double Engagement Half Gear Variety
The two inner and external teeth in a single sleeve. Can be bolted to a rotating flywheel, shaft or drum to connect driver or driven machine using a shaft extension. This coupling has the exact same attributes, ratings and misalignment capability as the standard group of couplings.
Rigid Alloy Steel FARR Kind
Male/Female piloted rigid coupling coupling with keeper plates. This coupling is utilised whenever a rigid connection is required between the reduced velocity shaft of the gearbox and also the head shaft of a conveyor, bucket elevator, mixer or any overhung or suspended load.
