High Capacity Bearings
Roller bearings have been designed to exceed minimum AGMA specifications for the most severe loading conditions with minimum friction and easy starting. You can count on bearing life well in excess of industry standards for most applications. Precise selection methods are based on data obtained from actual test of the drives.
Heavy Duty Shafting
Large shaft diameters are designed to maintain accurate support and alignment of gearing under the most adverse loading conditions, and provide optimum external thrust and overhung load capacities. Double ended low speed shaft extensions can be supplied at no extra charge only when specified on the order.
No-Leak Seals
Keep Oil In - The Falk "Magnum™" seal keeps oil in the drive and keeps dirt out. The inner cage has close fitting clearances between the shaft and bearing race which prevent oil from leaving the drive. The oil drain back ensures an effective seal by returning any oil that gets beyond the bush seal, back into the drive. Since there are no moving parts, this throttling bush seal arrangement will last as long as the drive if properly maintained.
Keep Dirt Out
An outer cover assembly, when filled with grease, prevents the ingress of foreign particles by trapping them before they enter the drive. Periodically, introducing fresh grease through the fitting in the cover, will purge contaminants.
AirMax® Breather
Unique Moisture & Particulate Protection for Enclosed Gear Drives (Optional Accessory).
Positive Lubrication
Continuous splash system is positive and thorough, and provides higher thermal ratings through the use of a large oil reservoir. Oil is carried to the working faces of the gear teeth through the oil troughs in the reservoir, than passes through the bearings. The system is basically simple, maintenance free and highly effective. Oil levels are easily checked with standard dipstick.
GMAX 6000™
Horsepower, Heat, Moisture, and abrasive contamination are constantly working to break down your gear drive lubricant. GMax 6000 is designed to provide superior wear protection in the most demanding gear drive applications. GMax 6000 is a Polyalkylene Glycol based lubricant or PAG. PAG synthetics have exemplary lubricating properties over traditional Polyalphaolefin or PAO Synthetics and mineral oils. The viscosity index of PAG lubricants is double that of PAO lubricants. This means that a PAG will perform much better over the range of operating temperatures experienced by an industrial gear drive.
Rugged Housings
All steel housings provide maximum strength and rigidity. Accurate machining ensures precise alignment of all revolving elements necessary to maintain engineering and performance advantages. The split housing design with large inspection cover makes maintenance easy. Surfaces are smooth, flat and easy to clean. The exterior is coated with the highest quality zinc chromate primer. The finish coat is sprayed with acid and alkali resistant enamel.
Precision Gearing
From the special alloy steel poured in our own foundry through the final finishing operation, constant quality control is maintained at each manufacturing step. Deep tooth form with high pressure angle allows greater surface durability, greater resistance to abrasion and breaking, and more load carrying capacity. High helical gear efficiency of 98 ½% per gear mesh remains constant throughout the entire life of the gears.
