Why Coupling Grease?
Ample lubrication is crucial for satisfactory gear coupling operation. Gear Coupling Grease is exclusively designed for gear coupling applications to boost coupling life although drastically reducing servicing time. Its higher viscosity base oil and tackifier combine to keep the grease in spot and avert separation and it is in full compliance with NSI/AGMA 9001-B97 lubrication suggestions.
Coupling Grease is dark brown in color and produced with a lithium soap/polymer thickener, which has superior resistance to oil separation when subjected to high centrifugal forces generally uncovered in couplings. Bearing or standard purpose greases have a tendency to separate and shed effectiveness resulting from high centrifugal forces within the many ingredients at high rotational speeds. These substantial centrifugal forces encountered in couplings separate the base oil from your thickeners. Hefty thickeners, which have no lubrication attributes, accumulate while in the gear tooth mesh spot resulting in premature coupling failure. Gear Coupling Grease is developed to very resistant to centrifugal separation of the oil and thickener, which enables the lubricant to become utilised to get a somewhat extended period of time.
Among the secrets to your good results of Gear Coupling Grease would be the variable consistency through the entire functioning cycle on the application. The consistency of our gear coupling grease improvements with the operating ailments. Operating from the lubricant underneath actual service ailments leads to the grease to develop into semi-fluid, functionally solash lubricating the put on surfaces in the coupling. Since the grease cools, it returns for the unique consistency, therefore avoiding leakage.
Gear Coupling Grease is obtainable from stock in 14 oz. cartridges, 1 lb. and five lb. cans.

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.
Limited End Float Spacer Style
The addition of plates restricts axial travel towards the drive or driven shaft. The spacer tends to make it achievable to take away the hubs from both shaft without the need of disturbing the connected units.
Vertical Floating Shaft Sort
The reduced coupling includes a hardened crowned button inserted from the plate from the reduced hub. The complete floating assembly rest around the button. Optional development on the upper coupling could be a rigid hub over the floating shaft with a flex half on the top.
This coupling has the exact same horsepower, RPM and misalignment abilities since the common couplings of corresponding sizes. A plate that has a hardened crowned button rests to the lower shaft which supports the weight from the sleeve.
Utilization of a non-metallic materials amongst flanges and close to the bolts prevents any stray currents from one shaft to the other.
Made use of on Jordan machines and refiners, this design is comparable for the slide style coupling except the long hub is split and secured to your shaft that has a bolt clamp. This permits fast axial adjustment on the Jordan shafts i this hub.
Engineered Shear Pin Variety
Shear pin couplings are mainly applied to limit transmitted torque to a redetermined load. THis in flip disconnectes the driver and driven shafts if torque exceeds the specified limits. They are really specifically suited to safeguard equipment when jams occur. Elements are re-useable right after pins shear. The coupling will retain lubricant for any short time period to permit gear for being shut down.
Brakewheel and Brake Disc Type
Replaceable brakewheel and brake disc piloted around the outdoors diameter of a common sleeve and/or rigid hub. Offers a choice of applying braking energy on the load or driving motor.
Double Engagement Half Gear Kind
Each inner and external teeth in the single sleeve. Is often bolted to a rotating flywheel, shaft or drum to connect driver or driven machine having a shaft extension. This coupling has the identical functions, ratings and misalignment capability because the common group of couplings.
Rigid Alloy Steel FARR Style
Male/Female piloted rigid coupling coupling with keeper plates. This coupling is used when a rigid connection is needed between the low pace shaft of a gearbox along with the head shaft of a conveyor, bucket elevator, mixer or any overhung or suspended load.
